Willoughby Britton, PhD is a clinical psychologist, an associate professor of psychiatry and human behavior at Brown University Medical School, and the director of Brown’s Clinical and Affective Neuroscience Laboratory. Her clinical neuroscience research investigates the effects of contemplative practices (meditation) on the brain and body in the treatment of mood disorders, trauma, and other conditions. She is especially interested in which practices are best- or worst-suited for which types of people or conditions and why. She is probably best known for her research on adverse effects—why they happen and how to mitigate them. Dr. Britton is the founder of Cheetah House http://www.cheetahhouse.org/, a nonprofit organization that provides evidence-based information and support for meditators in distress as well as meditation safety trainings to providers and organizations.

  This episode is brought to you by Eight Sleep. Temperature is one of the main causes of poor sleep and heat is my personal nemesis. I've suffered for decades tossing and turning, throwing blankets off, pulling the back on, putting one leg on top and repeating all of that ad nauseam. But now I am falling asleep in record time. Why? Because I'm using a device that was recommended to me by friends called the Pod Cover by Eight Sleep. The Pod Cover fits on any mattress and allows you to adjust the temperature of your sleeping environment, providing the optimal temperature that gets you the best night's sleep. With the Pod Cover's dual-zone temperature control, you and your partner can set your sides of the bed to as cool as 55 degrees or as hot as 110 degrees.

• 0:41Tim Ferriss?

  I think generally in my experience, my partners prefer the high side and I like to sleep very, very cool. So stop fighting, this helps. Based on your biometrics, environment and sleep stages, the Pod Cover makes temperature adjustments throughout the night that limit wake-ups and increase your percentage of deep sleep. In addition to its best-in-class temperature regulation, the Pod Cover sensors also track your health and sleep metrics without the need to use a wearable. Until November 30th, my listeners can save $350 on the Pod Cover. Go to eightsleep.com/tim, all spelled out. That's eightsleep.com/tim for these exclusive holiday savings.

  This episode is brought to you by Nordic Naturals, the number one selling fish oil brand in the US. More than 80% of Americans, that's probably a lot of you listening, including me, because I do measure my omega-3s, do not get enough omega-3 fats from their diet. That is a problem because the body cannot produce omega-3s, an important nutrient for cell structure and function. Nordic Naturals solves that problem with their doctor recommended, and in fact, this brand was recommended to me by one of my doctors, Ultimate Omega Fish Oil Formula. So the Ultimate Omega Fish Oil Formula for heart health, brain function. Immune support and more. It's incredibly pure and fresh with no fishy aftertaste.

• 2:16Tim Ferriss?

  So I have been taking Ultimate Omega for the last two months or so. And this fishy aftertaste issue has been a problem for me. And it's actually with other brands induced some nausea after a few days. And Ultimate Omega has been as clean as a whistle. I've had no issues whatsoever. And if you are vegetarian or prefer to alternate, I ended up alternating two products. And that is number one, the Ultimate Omega Fish Oil Formula. And also the Algae Omega, which is plant-based EPA and DHA. That's also from a Nordic Naturals. So I ended up getting both of those products and it has improved my recovery from workouts. It's improved my sleep. It has improved my mood.

• 2:59Tim Ferriss?

  And I know that because I pulled out a lot of other variables. In any case, back to the read.

• 4:33Tim Ferriss?

  Hello, boys and girls, ladies and germs. This is Tim Ferriss. Welcome to another episode of The Tim Ferriss Show. And it is my pleasure today to have Will B. Britton, Ph.D., on the podcast. She is a clinical psychologist and Associate Professor of Psychiatry and Human Behavior at Brown University Medical School and the Director of Brown's Clinical and Effective Neuroscience Laboratory. And that is A- effective with an A. Her clinical neuroscience research investigates the effects of contemplative practices, i.e. meditation, or certainly one example being meditation, on the brain and body in the treatment of mood disorders, trauma, and other conditions. She is especially interested in which practices are best or worst suited for which types of people or conditions and why.

• 5:16Tim Ferriss?

  She is probably best known for her research on adverse effects, why they happen, and how to mitigate them. And we'll be doing a very deep dive on this, certainly. Dr. Britton is the founder of Cheetah House, as in the large and very fast cat, Cheetah House, a nonprofit organization that provides evidence-based information and support for meditators in distress, as well as meditation safety trainings to providers and organizations. You can find Cheetah House on Twitter, @CheetahHouseOrg. Facebook, you can find at cheetahhouse.org, and on Instagram, @Cheetah.house. Dr. Britton, thank you for making the time today. Nice to see you.

• 5:54Speaker 04

  Thank you so much for having me.

• 5:55Tim Ferriss?

  There are many reasons that I wanted to have a conversation with you. And one certainly was due to my own experience at a silent retreat and having a flooding of traumatic memories and everything that that led to. It was overwhelming to an extent that I could not have imagined and certainly had not been prepared for. Secondly, is a mutual acquaintance, I won't mention his name because he is one of the more private people in the world, so I would always want to double-check, had suggested that we talk because there might be some mapping, or some similarities at least, between meditation-related adverse events and how symptoms present, some of the dissociation,

• 6:37Tim Ferriss?

  etc., that you can observe in some people, and some of the adverse effects that you can see, some persistent effects after psychedelic use. So eventually, we'll get to that. But let's start at the beginning, or at least with the genesis story of sorts. How did you first become interested in meditation?

• 6:58Speaker 04

  So I think, like many people, I had a life crisis that precipitated the need for something really different in my life. One of my childhood friends committed suicide when I was in college, the summer between my junior and senior year. And it was devastating and completely dysregulating to see a person just disappear from the world. Like, it wasn't in my repertoire of possibilities that somebody could just not be there anymore. So I had, you know, probably diagnosable PTSD at that point. And I really didn't want to take medication.

• 7:37Speaker 04

  I was only 20. My dad sent me A Path With Heart by Jack Hornfield. And that became my Bible for the next probably decade. And so for those of you who don't know, Jack Hornfield's a very famous meditation teacher, and he's written many books. And this particular one, like many of them, started off with just what the mind can do and how to work with it. And it just, you know, it was a very practical way to manage all of the emotions that were happening. And it was great because it was allowing them to be there, too. It wasn't suppressing them. Ironically, that particular book that he wrote, I only got about halfway through it because the whole second half, I just like could not relate

• 8:21Speaker 04

  to because it was like the spiritual roller coaster and like Kundalini awakenings. And I was like, I don't know what that is. So I'll just put that down. Just take what you need, whatever. And then that came back, fast forward 15 years, I was like, oh, right. That second half of that book, let me go back and read that. But I'm getting ahead of myself. So going into graduate school, I was also very, very interested in consciousness always, and always interested in just, what are we doing here? What's going on? What's looking out of my eyes? And like, just very curious. And so that was already happening. And then I had this, this experience, and it kind of culminated in my graduate career, looking

• 9:06Speaker 04

  at alter states of consciousness in a clinical psychology program at the University of Arizona, which happens to be, at the time, the only place in the world that had a consciousness studies center. So I was doing that. And actually, my sort of professional life

• 9:25Speaker 04

  I actually studied near-death experiences for my master's thesis and my own personal trauma and meditation practice was something I was doing on my personal time. It was not part of my scholarship. But I think at some point during graduate school, like those two lives were so divided that I needed to combine them just to be like an integrated human being. And so for my dissertation, I did a study on the effects of mindfulness training on sleep. I was working in a sleep lab and sleep is illegal altered state of consciousness and it's linked with every type of possible health issue. And so if you want to study altered states of consciousness, it's a good one to study because it's not

• 10:09Speaker 04

  like psychedelics that get banned. You know, it's everyone does it, happens every day.

• 10:13Tim Ferriss?

  Hard to ban sleep.

• 10:15Speaker 04

  Yeah. So it was a good one. It was a good one to choose. And, you know, at the time, this is two, around 2000, there really wasn't great research. A lot of the meditation research was on self-reports. There wasn't a lot of brain data available. And so I was going to be one of the first people to record overnight sleep polysomnography. So this is brain-based sleep and prove that meditation was improving sleep because of course it was. I mean, it's relaxing, you know, it's et cetera. So that was my dissertation and I spent like 200 nights watching people sleep. And at the end of the day, the hypothesis

• 11:00Speaker 04

  was not at all what I expected. So we actually found that no matter how you measured arousal, cortical arousal, brain arousal, meditation was associated with increasing it, not decreasing it. So it was causing insomnia in people. And we looked at percentage of slow wave sleep that went down. We went and looked at how fast the brainwaves were, those went up. And the correlation was with the amount of practice was point eight. So like, no matter where you went, there it was. And this is my first confession is that I didn't publish the data. You know, I was like an evangelist for meditation because I, this is something that had really helped me.

• 11:42Speaker 04

  And I really wanted to like, use my science and my position as a scientist to promote this thing. And so I didn't publish the data. At some point when I was coming, I came to Brown to do my residency. Couple of years later, I was on a meditation retreat and I mentioned the data that I had found, which is basically that it was causing cortical arousal and insomnia. And the meditation teacher sort of chastised me and said, I don't know why all you clinical psychologists are always trying to make meditation into a relaxation technique. Everyone knows that if you meditate enough, you stop sleeping. And I was like, what?

• 12:19Tim Ferriss?

  Bulletin.

• 12:20Speaker 04

  You know, yeah. And so that was kind of like a wake up call, literally. And I thought, okay, well, what other assumptions are we making? I was definitely pretty emblematic of a lot of people who go into meditation research or the average meditator, which is like, I didn't really know my Buddhism. I didn't really know my history. I just kind of signed up for whatever was around and believed everything that people said. And the way that it was marketed as a sort of health promotion tonic. I believed all that and I didn't do my homework, which is pretty terrible as a meditation researcher. And so I was like, okay, it looks like I need to do some history homework

• 13:03Speaker 04

  and really look at the background of what kinds of assumptions we're making as health providers. And like, really look at the translation process of how these practices, like where they came from, what kinds of changes they made, what was the journey like to get here into the West? And really unpack that process. And then the second question was, what other little nuggets of knowledge do these meditation teachers have that they're not telling us? And there's a follow on part of the story, which is when I came to Brown to do my clinical residency, you have to do a year of internship to see clients, basically to get your license.

• 13:48Speaker 04

  I worked at an inpatient psychiatric hospital and during that. One year, there were two yogis who came off retreat, completely psychotic. And I thought like, wow, two in one year is, it's kind of a lot. It seemed like a lot to me. So I went back to the same teacher and I said, well, have you ever seen this before? And I remember like distinctly that there was no actual verbal reaction, but there was this look of like, oh shit.

• 14:20Speaker 04

  And I was like, oh, wow. Like there is a story here. There is a knowledge that this can happen. And meditation teachers are sitting on this, just a ton of information that needs to be mined. And as a meditation researcher, I was like, okay, we need to start asking these questions. So that whole story is the beginning of the varieties of contemplative experience study, which was the simplest study that I've ever done, the hardest but simplest. And that it was basically just going to meditation centers and teachers and saying, what types of challenges have you observed in your students? How do you make sense of them? Like, what are they? How do you interpret them?

• 15:04Speaker 04

  And then very practically, what do you do about them? Very straightforward set of questions and that took 10 years. It's 3,000 pages of qualitative data. And I don't even know how many papers we've written, we're still writing papers based on that data. I think we're like over 10 now. It's really just a wormhole, which we're going to go down together.

• 15:30Tim Ferriss?

  Oh, we are going to go arm in arm down the wormhole. So let me pause for a second. I want to make a promise to folks and I'll give you a heads up also, we will come back to the near death experiences. I'm going to leave that as a Scooby snack at the end for people. So I do want to talk about that. However, I want to dig into the sleep for one second. If people stop sleeping, period, full stop, eventually they die. So the restorative functions of sleep, as it is, still poorly understood, but are critical to human functioning and survival. So how would you explain, if it is indeed true that if people meditate enough, they kind of stop sleeping, or they start sleeping very minimally? How would you explain that?

• 16:12Tim Ferriss?

  Is it that the meditation practice itself provokes a state that is restorative? And therefore, the sleep is less necessary? Or is there something else that you would put as the frontrunner for explaining that?

• 16:28Speaker 04

  We can point readers to various papers. There is a paper that was called Awakening Is Not A Metaphor. I had to fight hard to keep that title.

• 16:37Tim Ferriss?

  That's pretty good. That's pretty good.

• 16:39Speaker 04

  But it's a review of different studies across different types of methodologies, looking at how meditation affects the awake sleep system. It's not as straightforward as you stop sleeping, or you sleep less. It's going to be dependent on many factors. And I will say that in the study that I was just talking about, my dissertation study, we found a non-monotonic, nonlinear relationship. So people who are meditating less than half an hour and less than every day, they actually had an increase in sleep quality. But people who are meditating more than that, that's when it sort of switched

• 17:24Speaker 04

  and turned into they were prone to being more awake, more insomnia, more cortical arousal. So it's a sort of biphasic, nonlinear relationship. So just to recap, it's not going to give you insomnia, probably.

• 17:39Tim Ferriss?

  Automatically, yeah. Yeah, because when we talk about meditation, it's like, oh, you do meditation. It's kind of like, oh, you do sports, or you do exercise. It's like, well, there are a million different parameters and types and so on.

• 17:49Speaker 04

  Right, and I think, you know, one of the other papers that I wrote, which is called Can Mindfulness Be Too Much of a Good Thing? introduces this idea of

• 17:57Speaker 04

  At a small amount or an optimal amount can do exactly what the hype and the promotions and the advertising says. Like, there is a lot of truth in the advertising and the positive reports. But there's also, there's another side of the story, which often comes with, you know, sort of higher doses. So, one of the ways to understand this particular finding, and actually, a lot of the other ones that are on the hyperarousal spectrum, would be if you think about meditation as a attention-enhancing product. It gets often

• 18:34Speaker 04

  compared with, or sort of marketed alongside Ritalin and modafinil and coffee and caffeine and, you know, all these stimulants that help attention. And so if you think about meditation as one of those, I mean, think about what happens when you-

• 18:52Tim Ferriss?

  Spiritual modafinil, which is an anti-narcolepsy drug, for people who don't recognize it.

• 18:56Speaker 04

  Yeah, if you think about any of the consequences, and many of us have personal experience with a lot of these substances, taking too many of them. Just drink too much coffee, what happens? You have a panic attack and you can't sleep. You take amphetamines or cocaine, or, you know, whatever, whatever the stimulant is, you take enough of it, and it's going to be on the fear spectrum. And some of them, if you take enough of it, it's going to be on the psychosis spectrum, especially if you have sort of tendencies in that direction. So, it doesn't seem like a huge leap to think that, like, here's another attention-enhancing product that with certain people and certain types of

• 19:37Speaker 04

  doses, it's going to lead to a hyperarousal syndrome. And that's pretty much exactly what we're seeing. So that is one of the potential mechanisms.

• 19:45Tim Ferriss?

  So, what I might do for folks who just don't have the personal context on me that I alluded to earlier, is I'll tell- If it's okay with you, a bit of my story, which in some ways led to this conversation. And certainly it sounds like, based on what we were discussing before recording, that people have mentioned this to you. It's been a match made for many reasons. So I want to give folks sort of a contrast by giving present day and then the story of what happened to me at my silent retreat, which was a Vipassana retreat. So if we look at, for instance, the last two weeks, I have meditated twice a day, 20 minutes a day, very straightforward transcendental meditation. And there's lots of wacky weird stuff if you go deep enough and weird enough

• 20:30Tim Ferriss?

  with TM. But if you're taking it for the off the shelf offering and following the basic guidelines, I find it incredibly therapeutic. And I find also difficult to disambiguate. I haven't had any caffeine whatsoever in two weeks. So the combination of those two, for I suppose a lot of sensible reasons, seems to really help. I've been getting some of the best sleep in the last 10 years, probably in the last one or two weeks. I'm sure the abstinence from coffee and caffeine, no small part of that. And I've seen no adverse events whatsoever. And I've done a lot of TM over the years and other types of meditation.

• 21:09Tim Ferriss?

  But TM I find to be the easiest life raft of sorts. However, if we flashback and this sort of alludes to the paracelsus, the dose makes the poison. I approached my meditation retreat, and this was at Spirit Rock, which is a beautiful, beautiful facility, beautiful campus, really, run by excellent people. And ended up being very fortunate that the author of the book you mentioned, A Path with Heart, that Jack Kornfield was at Spirit Rock. He ended up being the person who effectively triaged and helped address the situation I found myself in ultimately. But I approached the silent retreat with The wrong mindset and the wrong set of expectations. I thought to myself, I've done

• 21:54Tim Ferriss?

  lots of meditation. If you add up all the time that I've meditated, it's quite a bit. I've spent time by myself and I've also done A, B, C, D, and E, really not recognizing that they are two different, for me at least, and for many people, two different species of experience. And since I had heard that it was the last time Jack would be leading a retreat, I'm not sure if that ended up being the case or not, I decided that I wanted to get absolutely as much out of it as possible. I'd seen benefits from fasting before. I'd seen benefits from lower doses of psychedelics before. So I thought to myself, this is probably aggressive, but why don't I combine all three? And that ended up being incredibly problematic,

• 22:39Tim Ferriss?

  but not immediately. I'd done the fasting. So I fasted going into this week-long retreat. And then after a few days of establishing my baseline, let's call it three days, I started adding, increasing doses daily of blended, like homogenized dried solace by mushrooms. So people might know these better as magic mushrooms, starting at about 100 milligrams and then slowly working up to about, I want to say it was 600 or so milligrams, which is reasonably high. It's far above what one would consider a microdose. Microdose, let's just call it 50 to 100 milligrams. And simultaneously, I'm having this first

• 23:21Tim Ferriss?

  experience of being silent for effectively the entire day, maybe outside of asking a question or two at a Dharma talk at night. This is brand new. And what ended up happening, just to jump to the punchline, is I was having difficulty with the meditation to begin with. I was very physically uncomfortable. My mind began to accelerate in terms of just rumination, the velocity of thought. And velocity sort of implies a direction. It was more like a ping pong ball bouncing around or a pinball bouncing around in a machine at increasing speed, sort of. Nonlinear exponentially growing speed and it was very uncomfortable.

• 24:04Tim Ferriss?

  And then I want to say around day four or five, I had this flooding of memories of childhood abuse. And it wasn't just snapshots. It was like being stuck in a fully immersive VR experience that was as convincing as this reality whenever I closed my eyes. So whenever I closed my eyes, that's what I saw. It was a re-experiencing of this traumatic, these traumatic experiences from age two to four. And if people go to tim.blog/trauma, they can listen to a podcast about this and certain modalities that have helped me. But nonetheless, I did not expect this and I was utterly incapable of stopping it.

• 24:46Tim Ferriss?

  I could not stop it and this went, talk about not sleeping anytime I closed my eyes. So I couldn't sleep. So now what do you have? You have compounding lack of sleep and I had never heard of this before. I didn't think this was a possibility. I certainly thought it was a unique experience, unique to me. I should be able to figure this out, but eventually got so desperate. I was like, I'm not going to be able to function. I mean, I am able to navigate my day to day here, right now with extreme pain, but I've no confidence I'll be able to go back to normal life and make decisions, manage my business, interact in all the ways that are necessary.

• 25:26Tim Ferriss?

  And that's when I set up meeting with Jack and thankfully he had the experience. He has a lot of experience also as a clinical psychologist with cutters, with people who have been abused, with veterans who have lost limbs and have moral injuries and PTSD. He has a lot of mileage with many different patients and clients and meditators. So he was able to, thank God.

• 25:53Tim Ferriss?

  Provide a safety net and provide me with recommendations to clinicians and so on, therapists I could meet to try to address this. But if he had not been there, I shudder to think what would have happened. So that's the story and ultimately was able to sort of pull out of it and manage life. But not everyone has access to Jack. And the contrast, and I'll shut up in a second, between my day to day over the last two weeks, all upside, and that experience are just black and white. I mean, there's, there's really no comparison. Interestingly, and I'll add one more thing. I recently spent a week in isolation in the

• 26:38Tim Ferriss?

  wilderness fasting for that entire week. And it was not nearly as challenging, but I did see some similar symptoms, let's say, in terms of that increased speed of the pinball bouncing around in my head, as did another person I was with. So two for two, without any attempt to meditate, which raises all sorts of questions, right? So it's hard for me to parse what caused what I experienced. But I know that it was terrible. And without Jack, I would have been fucked, for lack of a better technical term. How common is that kind of experience, I guess? And certainly feel free to start wherever you'd like, or pick that apart in any way that makes sense. But it was a disaster, unmitigated disaster.

• 27:22Tim Ferriss?

  And I'm very fortunate I had someone like Jack, because I'd actually spoken with one other junior teacher at the time, and she was unequipped. She was not equipped to handle what was happening. But Jack was.

• 27:37Speaker 04

  Yeah, so many different thoughts.

• 27:42Tim Ferriss?

  Thank you for coming to my TED Talk.

• 27:44Speaker 04

  I mean, one is just, wow. Wow, in so many ways, like, wow, that that happened to you. And two, that you're talking about it publicly.

• 27:59Speaker 04

  That's amazing. So, thank you, because I think it's gonna be really helpful to a lot of people. Maybe a second thought is, you're definitely not alone. You're definitely not the only one. There were probably other people on your retreat this was happening to, and that in my work at Cheetah House, I see someone like that every day. I try to see at least one person every day. I'm seeing someone later today, actually. So, this, to me, is like my bread and butter. I see it all the time. Like, it's so common, but what are the actual percentages is, that's where we get into

• 28:41Speaker 04

  the rabbit hole of research and frequency research, which is actually quite complicated, because it's about like, what do you mean by this?

• 28:51Tim Ferriss?

  Right.

• 28:51Speaker 04

  You know, and like, frequent among who? And so, it becomes more complicated. And I guess one other question is, given what I do, that I'm an expert on meditation-related challenges and neurobiology, is there anything that we can talk about that would be useful to you? Do you have any lingering questions that haven't been answered yet? Or, I'll just put that out there. And then another thing is, let's create a public service announcement for people like you, because, let me tell you, males 18 to 30, who think that combining every possible powerful tool, all at once, to, you know, break on through to the other side, is a story that I see again,

• 29:36Speaker 04

  over and over and over again.

• 29:37Tim Ferriss?

  Doesn't always turn out, all you're saying?

• 29:39Speaker 04

  Uh, no, it's more like a risk factor. And so,

• 29:43Tim Ferriss?

  Yeah, for sure.

• 29:43Speaker 04

  At Cheetah House, we have a program called Letters to My Former Self, where people come on who did stuff like that, and then they're like, "Honey, let me tell you like, what I wish I'd known when I was your age. You tell your former self advice. I would love you to do that."

• 29:58Tim Ferriss?

  It should also be a letter to your future self, so you don't do the same thing. Again, I do have a couple of questions, and, well, a few observations and a couple of questions. So, looking back at that experience, separately, prior to that experience and afterwards, I had a lot of experience with fasting, including extended fasts, and a lot of experience with psychedelics. And that was pre-meditation retreat and certainly post.

• 30:22Tim Ferriss?

  Based on my last experience over the last three weeks where I was in isolation in the wilderness, fasting and so on, I tend to weight, in this particular case, the fasting as an exacerbating factor more than the microdosing of psychedelics, which is not to recommend to anyone that they combine things on their first meditation retreat. Look, there are lots of meditation retreats. Do it the plain vanilla way first would be my strong recommendation. It's gonna be hard enough. Don't worry, would be recommendation number one. There are some people, and this is gonna lead to my question, like you've all know Harari, who wrote Sapiens, who I've had on the podcast, who does a silent meditation

• 31:04Tim Ferriss?

  retreat for a month every year, as far as I can tell, and handles it like a champion. It is like a warm bath for his mind. I found it much harder. I'm sure there are people who find it harder. My question is this. What are the, not necessarily exclusionary criteria, but what are some of the characteristics or profiles that make someone more vulnerable or likely to have this type of experience? Because for instance, if you look at classical psychedelics, and we could spend a lot of time defining what that means, but broadly speaking, let's just say with the usual suspects that a lot of people would recognize, let's say LSD, psilocybin, et cetera. There are certainly others. Ayahuasca could be

• 31:43Tim Ferriss?

  thrown into this for NNDMT. That if you have a family history of schizophrenia, it is likely a bad idea for you to engage with using these things, simply because, not to say that it will make you schizophrenic in a lifetime where you would otherwise not become schizophrenic, but it could expedite the onset of symptoms. And there are many documented cases of this. So in a case that you have a family history of schizophrenia, maybe you should not consume these things. And I'm wondering how you would paint the, what the intake form, right, should look like? What does the intake look like for a meditation retreat so that a facilitator could say, you know what, I think maybe you

• 32:25Tim Ferriss?

  should do 20 minutes a day or 30 minutes a day, but not do seven days silent, because that would be like taking ayahuasca for a schizophrenic? How would you think about the things that make it more likely?

• 32:37Speaker 04

  This is a very natural place to start, which is sort of, you know, screening out people who shouldn't meditate.

• 32:45Speaker 04

  And now I'm going to unpack why that's a very difficult thing to do. I conducted a epidemiological study with Vichy Davidson and Simon Goldberg, looking at meditation-related adverse effects, how often they happen, and risk factors. And so statistically speaking, there is an increased risk factor for a large range of variables that would be considered stressors, adversity. So, trauma history, psych history, being a, some kind of minority group, you know, whether it's racial minority or sexual orientation minority, something like that is going to be a chronic stressor, and that's going to be, you know, heighten the risk for adverse effects.

• 33:30Speaker 04

  And so it's very easy to just sort of, well, those people shouldn't meditate. You know, it's very easy to kind of do that. Well, first of all, more than 90% of people have exposure to a criterion, a stressor. So that would be like, almost everyone gets ruled out, except for the extremely sheltered and privileged, which would be not what we're trying to do with, you know, meditation is just limited to those people. And then in our, the varieties of contemplative experience study, we found that a lot of the risk factors that were the most obvious ones to consider, like psych and trauma history, they didn't know what they were doing, incorrect practice, that kind of thing, that none of those actually panned out to be true.

• 34:15Speaker 04

  And so in our study, 60% of the people who had meditation-related challenges were themselves meditation teachers. So they were getting correct practice instructions, they were meditating correctly, they had good supervision, they had good knowledge about what to do. And there were a number of people that did not have psychiatric or trauma histories. And so while those are risk factors, it doesn't mean that if you don't have them, that you're safe. So the sort of take-home message from me is...

• 34:53Speaker 04

  I'm not a big fan of screening people out. The other side of this is that there are a lot of people, and this might be not as true for psychedelics as it is for meditation, but meditation is being marketed for schizophrenia, for psychosis, for bipolar disorder, for all the things that you might as a retreat manager want to red flag. It would be just a strange thing to start saying, oh, you can't, those people can't have access to this technology. And I've gotten letters from people that say like, please don't just rule us out. People with what would be considered serious mental illness. So please don't just rule us out because we seem like it would be a bad idea for us.

• 35:38Tim Ferriss?

  Well, let me pause for one second and just say, it seems to depend on the type of meditation we're talking about, right? For meditating 20 minutes in the morning, there might be one intake. But for doing a seven day silent retreat, there might be a different intake. So I don't know if you're able to speak to that. Because those two things had about as much in common for me as like playing with a Hot Wheels car on the top of your kitchen table and like driving an F1 car around a hairpin. Like they were about, they're like, yeah, they both involve cars. Okay.

• 36:16Speaker 04

  Right. I guess my point is, is that I think that the action item here is not screening people out as much as being much more informed about how to monitor them closely and how to have more off ramps as part of their retreat.

• 37:51Tim Ferriss?

  I want to give people, just so not everyone is like, "Oh, my God, the next time I meditate, am I going to have a psychic implosion and end up in a stray jagged?" Just to put some numbers to things, I want to read something here and just have you fact-check this, so people have some numbers on prevalence, and also just a comparative sort of parallel of sorts that we'll spend a little bit of time on. Then I want to talk about safety training, monitoring, and off-ramps and things like that. So, this is from mindfulnessexercises.com, which is pulling from an interview with you. "With a more clear definition of adverse effects in hand, Will B. and her team set out to research the true prevalence of life-impacting adverse

• 38:33Tim Ferriss?

  effects following meditation. The first surprising result was that their epidemiological sample indicated nearly half of the US population has meditated at least once. I'm sure that's higher now. Of these people, 6 to 14% had lasting negative effects." So, that's what I wanted to bring up. "A number that closely emers the adverse effects of psychotherapy, 5 to 13%. Is that roughly accurate, would you say?"

• 38:55Speaker 04

  Frequency research is very challenging, and so I do think that the epidemiological study is probably the most valid research, but somehow that, the data that they're citing, is actually from combining two different studies. So the epidemiological study, the denominator was anyone who's ever meditated even once. So that's like kind of the lowest common denominator. So like the lowest possible chance. And within that study, we found that people who had tried meditation even once, half of them would have at least one negative effect. And it could be extremely

• 39:32Speaker 04

  brief, no big deal. More concerning is that 10% to 1 in 10 people who had tried meditation even once would have a meditation related adverse effect that was associated with impairment and functioning. And so we can go down the rabbit hole of definitions if you want, but I think that for me, like, having a negative experience during meditation, which I call negative valence, I don't consider that an adverse effect. I think that if you don't have some kind of negative experience in your meditation at some point, you're probably sleeping, because it's not a warm bath for the mind, it can be challenging. So I'm not worried about that part, but I'm more worried about if it has a negative impact on your

• 40:17Speaker 04

  life and functioning off the cushion, then I'm like, okay, that's when we need to start talking about whether there's maybe alternatives. And so 1 in 10 is really the number that is jumping out of that paper. The other paper, which was a clinical trial that I did, much smaller trial, very selected sample of people who have kind of clinical to subclinical anxiety and depression, that came up with a 5 to 15%, which is still, you know, they correlate with each other.

• 40:48Tim Ferriss?

  What are some things that we can do to risk mitigate in terms of, and you can pick whichever makes sense to start with, but training for instructors or monitoring, I'm actually pretty interested in the monitoring, I'm interested in all of it. And then off ramps, what to do if somebody does have a break, I suppose, like I did. I wouldn't necessarily describe it as a psychotic break, but I felt out of control, right? I felt like I was not able to, I would not be able to function normally had I returned to normal life without some intervention. What can we do to make things safer, I suppose?

• 41:26Speaker 04

  I think it helps to start with, we created a taxonomy of 59 categories of meditation-related challenges, and it wasn't until many years later that I went through the somatic experiencing trauma training, that I started to actually see a lot of those 59 categories in terms of trauma symptoms, and in terms of symptoms of the way that the body tends to react to extreme stress. And these are not necessarily so altered states, but things that might be somewhat recognizable to people. So, one of the ways that I think is the most efficient

• 42:08Speaker 04

  way, because we can train meditation teachers, and we're like, I have, you know, online courses where you're like, they have quizzes on the 59 categories, and you, you know, there's all this content that they need to learn. But I actually think that the best way to do it is to train each individual person, is to be like, "Tim, how do you know when you're getting outside of your window of tolerance? How do you know when you're feeling quote unquote, 'out of control'? Like, what is your indicator for that?"

• 42:37Tim Ferriss?

  It's when I seem incapable, or maybe when I am incapable, of stopping very high-speed negative rumination, I suppose. It would be like perseverating on either a real event, like a memory, or a perceived threat, like a hypothetical worst-case scenario, and I just loop and loop and loop and loop. And I'm furthermore aware of the looping. There's part of me, as the observer, that's like, "Holy shit, I can't believe I seem incapable of stopping this. I know it's not productive. I know it's not helping me." And yet, it

• 43:15Tim Ferriss?

  just goes and goes and goes. That would be my canary in the coal mine, or maybe a flock of canaries in the coal mine.

• 43:24Speaker 04

  So, is there anything that is an earlier indicator than that, before you get there?

• 43:30Tim Ferriss?

  You know, I would say it's more I've realized which factors can contribute to that. It's something for me that comes on. So this may be a dissatisfying answer, but it's something that can come on really suddenly. But I would say that over-caffeination, lack of sleep, fasting, there are a handful of things that seem more likely to precipitate this type of experience than other things. It doesn't happen all the time, but I would say probably if I were to try to back into what I described, I'm sure that it starts with, and I'm sure it started, I have to imagine at my Vipassana retreat with having bouts of this come up

• 44:14Tim Ferriss?

  and then trying to suppress it. I'm sure that it took some form like that. I would have to imagine it was something like that.

• 44:22Speaker 04

  So, you know, just to quid pro quo, I mean, I have lots of them, but I think my mouth gets dry. It's like an indication of sympathetic activation.

• 44:32Tim Ferriss?

  Interesting. Yeah.

• 44:33Speaker 04

  I get really hot. A strong stressor for me is when my visual field starts to get wonky and that's when the sort of dissociation sets in, things get a little spacey and like you're, you know, that. So if this was a meditation class, I would have everyone go around and talk about their own personal indicators. Because no matter how much research we do, those indicators are, there's going to be a lot of overlap, but there are also going to be some individual differences. And really what matters is that the person knows what their indicators are. They're like, my system is stressed. Don't keep doing what you're doing that's making this happen. Let's dial it back. And unfortunately, the

• 45:16Speaker 04

  response is often like, well, just keep going, just keep meditating, keep doing whatever you're doing. At some point, there's going to be a breakthrough, but instead, it's just gets worse. That is more of the angle that I'm taking is like teaching everybody what their indicator lights are. You don't get in a car and drive until you know like the gas meter is here, like this is the tire pressure, like you know, you have these indicator lights and we have them. We have indicator lights and we all need to be sort of trained on what they are individually. And that will keep you a lot safer when you know what your indicator lights are. I think one of the things that undermines that is this sort of fascination and romanticization

• 46:00Speaker 04

  of altered states. And you can think of altered states as a deviation from baseline, a deviation from homeostasis, which is, in trauma speak, that is dysregulation. An altered state is not necessarily a good idea for someone who's trying to stay stable. And so just having people be able to track that and, okay, like that thing, my indicator light is on, what typically helps that? And go do that. I need to go lift some weights. I need to go dial back and skip the coffee this afternoon or like maybe eat something. By the way, the fasting thing is really interesting.

• 46:42Speaker 04

  We had a lot of information in the varieties project about diet, but we really hadn't done anything with it. And actually, one of my students this year has just started to delve into the diet data and is finding that it's really making a difference, that a lot of people have reported that when you go on meditation retreats, because they tend to be vegetarian and they tend to feed you very light food, sometimes not even, there's, sometimes there's no dinner. And so, you know, it's not fasting so much, but it's definitely like you're going off of your, like my personal high fat, high protein diet, like I get very unregulated and floaty and sort of ungrounded when I go on retreats and I really want to have like heavy food.

• 47:27Speaker 04

  And so, a lot of people found that to be a factor and found that actually eating really high fat, protein, meat is a remedy.

• 47:37Speaker 04

  For problems. And this is also, you know, recommended within Tibetan medicine and like an old Buddhist texts, textual reports will also report eating meat and heavy foods. Oils can also be something that can help sort of bring people down and more grounded. And when we interviewed the teachers as teachers, which was the second part of the study, there was really not a lot of consensus about like what was a problem, what wasn't a problem, what was a risk factor, what wasn't. But there were two things and one was when the person stops sleeping and when the person stops eating, that's when you intervene. So those were the two things that people, all teachers, mentioned as being something that they worry about.

• 48:22Tim Ferriss?

  Let me hop in for a second, just to mention something that I found in the process of doing homework for this. This was actually in a Harper's piece about you and your team. And it discussed something that I've also seen, which does not really get discussed. So I'm bringing it up very deliberately, post certain potent psychedelic experiences. So this is something that I've seen in both, well, actually, I should say now, I've seen described here as a adverse effect of meditation, possibly for some folks. And also I've seen this post psychedelic. And this is, I'll just read, quote, "Practicing letting go

• 49:05Tim Ferriss?

  of concepts, one meditator told Britain, was sabotaging my mind's ability to lay down new memories and reinforce old memories of simple things like what words mean and colors mean." What I'm going to underline is what's coming next. "Meditators also reported diminished emotions, both negative and positive." Quote, "I had two young children," another meditator said, "I couldn't feel anything about them. I went through all the routines, you know, the bedtime routine, getting them ready and kissing them and all that stuff, but there was no emotional connection. It was like I was dead." End quote. So this anhedonia, let's call it, which interestingly can also be, for some people, addressed with psychedelics. But what's less talked about is that it can be initiated in some people by psychedelics, where they come out and they're sort of numb to the world. And

• 49:50Tim Ferriss?

  People think of the amygdala as this fear center, but it's not exactly a fear center. So maybe you could just speak to this particular manifestation of issue, because I've seen it in both camps.

• 50:01Speaker 04

  There's kind of two different ways that this can happen with meditation and psychedelics. With meditation, if you look at the neuroscience of meditation, and there's lots of different kinds, but like, we'll just say like, concentration practice, you tend to see, you know, a down regulation of the limbic system, the amygdala, and, you know, activation of the prefrontal cortex. So attention system goes up, down regulates the limbic system. And again, this can be great, good things. You regulate all your anxiety and depression. But if you keep going, then you're going to see a down regulation of not just negative emotions, but also positive ones.

• 50:44Speaker 04

  People forget that like, the amygdala is, you know, a salience detector for all sorts of things, positive and negative. And you're going to see, if you continue to down regulate your limbic system with meditation, and you take it far enough, then you will see a decrease in the intensity of all emotions, otherwise known as anhedonia. According to, you know, Obisakari, that could also be something that could be equanimity. So depends on what you want.

• 51:13Tim Ferriss?

  Tomato, tomato.

• 51:15Speaker 04

  Obviously, the person who didn't feel anything for her children, that was not her goal. But I actually, that particular quote that you're reading, I read that quote in a conference and a Buddhist scholar like jumped up at the end and said, "Cutting attachments with, you know, affection with your families is exactly what you're supposed to be doing." And so I was like, okay, well, we need to talk about what your goals are. So.

• 51:39Tim Ferriss?

  Yeah, thou doth protest too much.

• 51:42Speaker 04

  With meditation, like, there is overlap. So what's interesting about that model, prefrontal cortex control over the limbic system, is that that's also the neuroscience of dissociation. So there are certain forms of meditation that mimic. The exact neurobiology of dissociation. So that's one way to end up in this place. The other way, so I call that the low road because you're just basically just taking everything down, getting calmer and calmer and calmer. The high road is the one we were talking about earlier where you're training your attention and everything's upregulating and you're getting more and more and more, like your thoughts are racing and you're having flooding of traumatic experiences and you're, you know, everything's getting heightened.

• 52:26Speaker 04

  And at some point, your system's like, whoa, this is too much. And you have this beautiful adaptive, natural breaker switch called dissociation. It'll basically shut down the limbic system again. And you'll basically end up in that state, the first state that I just talked about, where you have like a strong activation of the prefrontal cortex and a downregulation of the limbic system. It's two different roads to the same place. And so what's interesting and sort of the overlap with psychedelics is that that too much kind of response that can lead to dissociation, it doesn't always have to be negative.

• 53:07Speaker 04

  People can have like a euphoric, unitive experience where they merge with the universe or they have just something, just ecstatic kind of experience. But their organism is like, that was too intense. That was too much for me. I'm turning on the breaker. And they wake up in the morning and they're like, they feel dead. And they spend years trying to recreate that awesome experience. But, you know, they're not really listening to their organism's messages, which is saying like, that was too intense. Are you listening? There is a very interesting overlap at Cheetah House when people come for help. We see the combination of psychedelics and meditation very often.

• 53:47Speaker 04

  A lot of times in this scenario where they go on a meditation retreat, have an ecstatic experience or just a very intense experience, wake up feeling dead and anadotic. And they think, I gotta sort of shock the system back into action. And they go take a psychedelic. And that just makes things worse because the system's like, I've been trying to tell you that this is too much and now you're just really pushing the envelope. And we also see the opposite. People who have the initial experience on psychedelics and then they decide, well, I'm very dysregulated. And they get told by various

• 54:27Speaker 04

  Authorities, you should go on a meditation retreat or you should meditate. Either way, at least the people who show up at Cheetah House, the combination was not the answer for them.

• 54:36Tim Ferriss?

  Let me hop in for a second just to ask a few follow up questions on retreats specifically. Are there any intensive retreats that you recommend or extended retreats? And I suppose the broader question is, how can one know where to practice and vet properly, right? If someone wants to do a meditation retreat? And the reason I ask is, for instance, with psychedelics, which are still largely underground at this point, even though at some point, hopefully, there will be an entire framework for administering them reasonably safely to people who fit certain criteria.

• 55:19Tim Ferriss?

  If someone finds a facilitator who says, no one under my care has ever had a bad trip, that is a huge red flag because it means they're either deluding themselves, they're lying, or they're really inexperienced. Those are kind of the only options on the table because you're effectively using nuclear power to change the plasticity of the mind. Of course, there are going to be adverse events. Of course, there are going to be outliers. And so you want someone who has actually handled those cases to push my F1 analogy. If you go to a racetrack, let's just say, and you're going to a track day, and the track runner says, we've never had any accident of any type on our track.

• 56:02Tim Ferriss?

  That's a bad thing because someone's going to have an accident. You want to make sure they have protocols in place, they have experience, they have the presence of mind to handle it calmly, et cetera, et cetera. So I could see that applying also to vetting meditation retreats. But putting myself in the position of someone listening to this, I might say, holy shit, of the people who've tried meditation once, X percentage have these persistent problems like this seems really, really dangerous. Maybe I just shouldn't meditate. So to maybe offset that a little bit, are there retreats that you? Ever recommend and how can someone vet if they're considering doing a retreat?

• 56:41Speaker 04

  A lot of it has to do with matching the goals to the person. So I don't want to necessarily rule out or recommend any particular retreat across the board. I think that there are certain retreats that are pretty repeat offenders and those are ones that have like high dose, you know, 15 hours of meditation a day, no movement practice. Often you see an alternation between walking and sitting and sometimes there's even yoga added. So more intense practices with

• 57:21Speaker 04

  no movement and also not necessarily tailored feedback from teachers. So I would be very careful before going on one of those. And I think just in general, there are so many different options for retreats these days. You can do like an afternoon retreat where it's only a couple hours. Start there. Titrate up and you can do this at home. You don't even have to necessarily spend the money. You can just download an app and do that for a day and see how you do, you know, like titrate up and add a day at a time rather than signing up for a 10 day retreat.

• 57:58Tim Ferriss?

  Something I have not mentioned before is that I've done shorter meditation retreats, like two or three days with no issues whatsoever. So I just want to point that out. The other fine detail that I want to mention, because I think Spirit Rock runs a very good ship and I think they're very well formatted and they do have safeguards in place that they explicitly advise against fasting and I violated that rule. I overrode that.

• 58:27Speaker 04

  Right.

• 58:28Tim Ferriss?

  And also added the psychedelics, which certainly I had not mentioned to anyone until I had already sort of capsized.

• 58:36Speaker 04

  Yeah, this never used to be an issue, but I know that people are doing that, that people are bringing psychedelics on retreats. And I think a lot of the retreats, they have to manage a lot of people. People are already having like challenging experiences, the regular kind of challenging experiences with meditation. And so to have to manage people who are also taking psychedelics is, that's a lot. It's not really fair to a meditation retreat.

• 59:07Tim Ferriss?

  No, it's going to be invisible to them for the most part.

• 59:09Speaker 04

  Yeah.

• 59:09Tim Ferriss?

  I'm sure, right? It's not going to be reported.

• 59:12Speaker 04

  Well, right.

• 59:12Tim Ferriss?

  Just like people lie on their medical intakes about the psychiatric medications they're taking if they are wedded to taking psychedelics with facilitator. This happens all the time. People sort of misrepresent their health status because they're so vested in this last hail mary, Obi-Wan Kenobi, you are our final hope solution panacea that they see in psychedelics. And I have to imagine that also happens with meditation retreats. I should also say, I'd love for you to say a bit more about repeat offenders. Are there any other characteristics or format issues that you see producing more problems than others outside of what you already mentioned?

• 59:54Speaker 04

  So in terms of the retreat or meditation type or in terms of personal risk factors?

• 59:59Tim Ferriss?

  The retreat or meditation type that seem to produce a higher volume of people with these issues.

• 1:00:07Speaker 04

  I would say retreats that recruit or are attracting a certain type of meditator, which by the way, like you fit the bill like pretty exactly. When I heard the story, I was like, wow, that's pretty emblematic of.

• 1:00:22Tim Ferriss?

  Textbook.

• 1:00:22Speaker 04

  Yeah. Young male, pretty educated, combining all sorts of tools, you know, fairly aggressive. We used to joke that one of the risk factors was zealotry, a kind of zealotry, a zeal. So something like that. And so there's a certain kind of almost like military. This is going to be a really, really hard retreat. Those types of retreats are a little bit more high risk. And I think there's also the combination of the person and the teacher slash format. One of the things that we found that was really shocking in the varieties of contemplative experience study is that on one hand, we expected to see people who ran into problems as people

• 1:01:08Speaker 04

  who had lots of problems in their lives. But when we actually like looked at the data, 75% had graduate degrees, MD, PhDs, JDs. These were like CEOs of major companies. These are like super high achieving people. And we're like, this is so interesting. How do we make sense of that? And we're like, oh, right. Being a high achiever is a risk factor.

• 1:01:29Tim Ferriss?

  I was just about to say, like, the drug addiction in the medical profession is off the charts, like suicides off the charts. So.

• 1:01:37Speaker 04

  It's because these are the kinds of people that you're like, okay, you're gonna sit and follow your breath. And they're like, okay, like, they're the ones that show up early for the meditation and they're the last ones to leave. They follow instructions exactly. They would never modify the instructions for their own benefit. That would not even occur to them.

• 1:01:57Tim Ferriss?

  Unless they make it more intense.

• 1:01:58Speaker 04

  You know, the kinds of people that, and this is kind of where trauma comes in. If you've been trained to scan, what are the expectations here? What are the sort of unspoken social rules that I need to ace in order to not be punished? If that's like kind of your MO running in the background, then we have all these people like following instructions exactly, not modifying them, basically listening to an external authority rather than their own internal compass. That's the recipe for disaster. And so if you can interface with really any type of meditation spiritual system with maintaining your inner compass, that's

• 1:02:42Speaker 04

  going to be a recipe for a much better outcome. Not everybody can do that and not all systems are tolerant of that. And so I would also encourage, and we've had lots of trainings with meditation centers, trying to be able to be able to be more flexible. And so if somebody knows, like, I need to be able to leave the meditation in the middle so that I'm not continuing to meditate. And the meditation retreat manager is like, no, that won't be allowed. You have to stay. If you come, you have to stay for the whole thing. That's not really allowing flexibility. So are there ways that people can titrate the amount of practice that they're getting within a retreat? Is there a way to like, hey, on Wednesday,

• 1:03:23Speaker 04

  we'll have burger night for people who need to like, increase the like, fat intake, you know, that is actually happening now.

• 1:03:30Tim Ferriss?

  The vegetarian diet piece is super interesting. I mean, I don't know if the acuity is sufficient as a factor, but it makes me think also with, for instance, some of these conditions that are, let's just say, contraindicated for most psychedelic use, schizophrenia, borderline personality disorder, understanding these are all kind of like word salad things taken from the DSM, which is kind of a big question mark for a lot of reasons. But some of these more, for lack of a better term, sort of chaotic conditions are contraindicated, respond really well to something called metabolic psychiatry with, and Chris Palmer has spoken about this out of Harvard, using high fat, effectively ketogenic diet, but like high fat, moderate protein. Some of these people respond incredibly well. So if you look, though, at the food

• 1:04:15Tim Ferriss?

  served at these meditation retreats, uniformly, effectively, the exact polar opposite, right? Which is kind of interesting. Do you meditate? Do you meditate now? Or is that not a practice for you?

• 1:04:25Speaker 04

  Ooh, that's a long, long story.

• 1:04:28Tim Ferriss?

  All right. Let's do it.

• 1:04:30Speaker 04

  Depends on what you mean by meditate.

• 1:04:32Tim Ferriss?

  Okay.

• 1:04:33Speaker 04

  So meditation, when I first undertook it, you know, with Jack's sort of meditation, came from a specific tradition. And it had a whole bunch of implicit goals and values that weren't really clear to me because I was just like suffering. And so I thought, I'm just going to do this so I won't feel so much panic and anxiety and et cetera. And so, you know, I've done tens of thousands of hours of meditation. I've been, you know, the expert meditator in many brain imaging studies. Like, I've done my time as a Buddhist meditator. But I've started to understand that there's a whole set of implicit values that like, I didn't necessarily choose.

• 1:05:19Tim Ferriss?

  What would be an example, if you don't mind?

• 1:05:21Speaker 04

  An example is that the ideal affect or the goal emotion state is more on the calm end of things. And as a direct descendant of General George S. Patton, it's not really in my blood to be calm. So.

• 1:05:39Tim Ferriss?

  More of a border collie and less of a great Dan, yeah.

• 1:05:41Speaker 04

  Yeah. Anyway, there's lots of people who their ideal state is not calm. And so there's lots of implicit values and I think that this is just something as meditation is moving into the West and kind of mixing with a lot of different cultures and subcultures and goals and values, like can these contemplative practices be used for many different types of goals rather than ones that were preset as part of a religious practice? And I think that is happening, but for myself in particular, I have, you know, specific

• 1:06:22Speaker 04

  practices that I do that I have permission now from myself to modify a practice to not just follow the rules the way that I did before and end up somewhere that I didn't want to go, but rather to modify things and make sure that I'm going where I want to go. But that also requires me to like actually sit down with myself and be like, where do you want to go? Which is another thing that I recommend for people. Amy Mann has a song, "Write Down What You Need Before You Sign Away the Deed." Make sure you know like what you want because you're going to get on a highway and it's going to be kind of fast tracking you to somewhere, making sure that you are actually going where you want to go.

• 1:07:04Tim Ferriss?

  I want to know what practices that you follow, not to imply that anyone should just copy paste, right? You've got to know your own needs, but I am curious like where you've landed personally. You tell me, where would you like to start?

• 1:07:15Speaker 04

  I want to go to the varieties of contemplative experience. This was a study that took us 10 years and we came up with 59 categories of meditation related challenges and adverse effects. And we categorized them into seven different domains, cognitive, perceptual, affective, which is emotional, somatic, cognitive, which is motivational, sense of self and social. So I'm not going to go through all 59, people can look them up, they're on this Cheetah House website under symptoms, but just to give you a sort of basic overview of what is in each category. So cognitive types of experiences are increase in thought frequency, which you talked about.

• 1:07:58Speaker 04

  You know, trouble with executive functioning, so making decisions, paying attention, the loss of conceptual meaning structures, which you also mentioned. Probably the most famous example is the woman who, on the way back from retreat, stopped at a red light, saw the red color, but didn't register what it meant, that it meant stop.

• 1:08:19Tim Ferriss?

  Oh, boy.

• 1:08:20Speaker 04

  You can see how that would be.

• 1:08:21Tim Ferriss?

  Problematic.

• 1:08:22Speaker 04

  Sometimes you need your concepts.

• 1:08:24Tim Ferriss?

  Executive function, you need your concepts.

• 1:08:26Speaker 04

  So that's the cognitive domain. Perceptual, you see perceptual hypersensitivity, you can also see hallucinations, visions, changes in perception, also changes in derealization, so feeling like you're in a dream, or things feel flat or cartoon-like. Emotions can go in either direction, which you've already kind of touched on, so increases in fear and panic and re-experiencing of trauma, but also affective blunting, so loss of emotions altogether. You can also see, in the somatic domain, we can see else's, energy-like somatic experiences, we have an entire paper on that.

• 1:09:03Tim Ferriss?

  Wait, say that again, what does that stand for?

• 1:09:05Speaker 04

  Else's, energy-like somatic experiences, so experiences of

• 1:09:09Tim Ferriss?

  What does that?

• 1:09:10Speaker 04

  sort of electricity or voltage or going through the body. We talked about insomnia already, and lots of different kinds of pain syndromes, headaches, different kinds of pains. In terms of cognitive or motivational, again, insane, just enlightenment or bust kind of changes in motivation. Sorry, honey, like, I'm gone, I'm gonna go shave my head and become a monk, like, we see that all the time. And then the opposite, complete loss of motivation, why would I do anything, no goals whatsoever. The sense of self domain is my personal favorite. I teach an entire class on it called Me, Myself and I. But there's lots of changes in senses of self.

• 1:09:55Speaker 04

  And that can range from the narrative self, the story of me, your identity self, all the way down to your sense of ownership over your own body, over body sensations, emotions, thoughts, and then also down to your sense of self, other self, world boundaries can dissolve. We have a whole paper on that as well. And obviously, there's a lot of overlap with psychedelics, with that particular category. So we can unpack that if you want. And then, within the social domain, not surprisingly, if you're having these experiences, it can be related to some social consequences. People don't like hearing about this. They have all sorts of reactions.

• 1:10:39Speaker 04

  Wait till you get your responses to this episode.

• 1:10:42Tim Ferriss?

  Yeah, I want to talk about the Dalai Lama too.

• 1:10:45Speaker 04

  Yeah. People don't like to hear about this. So you get, so a lot of people get shunned by their communities. Sometimes, you know, their teachers get irritated with them. And then there's also trying to go to work and trying to explain why you can't function. So there's all sorts of social dynamics that go with that. That was kind of the quick and dirty overview of the 59 categories. And I will say that within that particular study, the varieties of contemplative experience study, we looked at duration of symptoms and duration of impairment. And duration of impairment, the average was one to three years. So it was quite a bit of time. And it ranged from a few days to more than a decade.

• 1:11:28Speaker 04

  So this can be, and I think, you know, your experience, you can kind of understand why. It could be quite a long time before you recover. If you don't happen upon Jack Hornfield for a while.

• 1:11:41Tim Ferriss?

  Yeah, I was, I won the lottery on that latter part of things. And you know, the duration you're describing, I just want to draw a couple of parallels. You already alluded to this, but you could take almost everything you just mentioned, if not everything, and map it to adverse events related to psychedelic experiences. Pretty much everything, I think everything that you mentioned. And in terms of duration, there's something that doesn't get talked about very much, also because it is viewed as perhaps risking the cause and the momentum of the psychedelic renaissance, but there's something, it's a bit of a mouthful. I wish it had a better name, but HPPD, hallucinogen persisting perception disorder.

• 1:12:26Speaker 04

  Yep.

• 1:12:26Tim Ferriss?

  And I know people who've experienced this where they are effectively hallucinating on some level for years.

• 1:12:33Speaker 04

  Yep.

• 1:12:33Tim Ferriss?

  I have a family member who experienced this by marriage. I have a very close friend who experienced this for the second half of his undergrad and for several years afterwards. And people can find more on this online. But I suppose we could move into scaffolding, but I'd like to ask you, are there any particular distinctions, clear differences between meditation-related adverse events and psychedelic-related adverse events?

• 1:13:03Speaker 04

  Well, we don't really know. That's actually a study that we're in the middle of collecting data on. So I'm glad that you mentioned that there's a lot of overlaps because I'm also seeing them. And a lot of people that have had both experiences are mentioning that there is a lot of overlap. So the study that we're conducting is basically looking at, basically seeing how much they overlap and whether there are systematic differences. If I had to guess, I would say that the perceptual changes, the HPPD-like changes, would be more common in the psychedelic world. I do think there's something neurological going on there that might be not happening

• 1:13:47Speaker 04

  in all forms of meditation, but we definitely see like visual snow and there can be some perceptual changes that are enduring, visual changes that are enduring. But if you look at the HPPD literature, it's actually a lot more than just visual changes. There's a whole lot of different things going on. So yeah, I think that's a really interesting question. How they compare, but also with whether somebody is a dual user and whether it's changing that way.

• 1:14:17Tim Ferriss?

  A lot of people are dual users. Yeah, it's very hard to disambiguate. The resource I want to recommend, and I can't vouch for it personally, because fortunately I do not have HPPD, but the more people use these compounds, meaning psychedelics of various types, the more this is going to become prevalent and really need proper addressing. There is a website. It's perception.foundation, and that's the Perception Restoration Foundation. They have resources, they have frequently asked questions about HPPD, they have a documentary trailer, they also have a specialist directory. I cannot vouch for the capabilities of any of the specialists, but a lot of people who

• 1:14:58Tim Ferriss?

  experience this feel the way I did in the midst of my silent retreat, which is, I am broken, I don't know how to fix this, everyone else seems fine, I don't even know what to call this, and there's a real sense of futility or hopelessness that can come with that. So suffice to say, the Perception Restoration Foundation may be a place to start. I can't vouch for it, but perception.foundation for folks who may want to look that up. What is scaffolding?

• 1:15:30Speaker 04

  For people who come to Cheetah House, and let me just back up a little bit about the Cheetah House sort of origin story. I mean, the actual Cheetah House started as a halfway house for Brown students who wanted to become monastics because of our Contemplative Studies program. So kids will get meditation training in school as part of college. They get so inspired by it that they want to go to India and ordain as monks, and going there and coming back and living in dorms as celibate, non-intoxicant-taking college students doesn't really work. So they lived at Cheetah House.

• 1:16:10Speaker 04

  That was the sort of, the original function of Cheetah House was to support sort of semi-monastic Brown students.

• 1:16:17Tim Ferriss?

  And is it true, Cheetah is a play on words?

• 1:16:20Speaker 04

  Cheetah is a play on words. It's a play on the Sanskrit term chitta, which means... loosely mined. When we started doing the varieties of a contemplative experience study, we were interviewing a number of people who were having meditation-related challenges. And some of them had just gotten out of the hospital. And, you know, they're like, I'm 27 and I'm living with my parents. Like, can I live with you? And so I live at Cheetah House. So this is like, you know, my house. It's a big Victorian house with lots of floors. And so there was an entire floor where meditators could live and kind of recover from whatever was happening. So that was the beginning of Cheetah House. It is now entirely online and is helping people recover from meditation-related challenges.

• 1:17:05Speaker 04

  And a number of them, they are not able to meditate at all. They're not able to engage in anything that looks like meditation. All the trauma cues and associations are around everything meditation. So, sitting with your eyes closed, sitting on a floor with your legs crossed, using a soft voice and guidance, like, all of that triggers the response.

• 1:17:32Tim Ferriss?

  Trigger City.

• 1:17:33Speaker 04

  Basically, half of the like, mental health world just becomes inaccessible to these people. Because, you know, they go to a therapist and the therapist is like, "Oh, you need to do mindfulness." And they're like, "No, not mindfulness, please, anything but mindfulness." So, we have to figure out a way to like, help people, you know, build their own practice. And I think the other piece that I wanted to unpack with you is, you know, after I heard your podcast, was the term ideological power. And so ideological power is the power to control meaning, language, and which concepts are available and how they're used. The power to interpret your own or others' experiences, behavior, or feelings, and the power to silence or undermine.

• 1:18:18Speaker 04

  The important thing here is that trauma is associated with powerlessness and a lack of options and a lack of agency. And so, for people who have been traumatized by meditation or meditation systems, any kind of system is also...

• 1:18:40Speaker 04

  A form of ideological power over them. Even like CBT is a system. Any kind of therapy or model is a system. And so that also becomes something that they're not able to work with because it feels controlling. It feels like it's some kind of value system or model that's being imposed on them. So how do you work with that? And so we have to start with, so this is called person centered approach. So if you were my pretend client, I would ask you like, before you started meditating, or just outside of your meditation life, what is something that is a resource for you?

• 1:19:19Tim Ferriss?

  Just for a general wellbeing? Are we talking about psychological wellbeing as a resource?

• 1:19:24Speaker 04

  I mean, what I typically do is actually ask you to look around where you are right now and pick something like a tangible object that's in your immediate vicinity. That's something that's meaningful to you, but unrelated to meditation.

• 1:19:37Tim Ferriss?

  Okay. Right, I was gonna say intense exercise. I mean, like I've, I've told every girlfriend I've ever had, if you see me trying to sit down and think my way through a problem for more than like a half hour, just tell me to go lift some heavy stuff for an hour. It's just like, tell me to get out of the house and go exercise and chances are it'll resolve itself. But if I'm looking for something meaningful that is near me right now, there's quite a bit here around me at the moment. I could say there's a artist's sketchbook for working with mostly graphite and ink, where I do some drawing. There's a copy of The Prophet by Khalil Gibran, which I read when I hop in the sauna.

• 1:20:21Tim Ferriss?

  I'll just read a couple of pages frequently and then put it down. I could keep going, but those are two.

• 1:20:26Speaker 04

  So as you're scanning the environment, when I ask you like, notice something that's meaningful. There's a salience glomming on to different objects, skipping over certain areas, but glomming on to certain objects. But it's not that the salience has a different flavor for each one. So if you were gonna think about, I'm gonna take my nervous system in that direction. I'm gonna take it in that direction. You could actually start to chart where you could go, different options, just by looking at these different objects. They're kind of telling you, oh, this will be activating, this will be energizing, this will be calming, this will be strength inducing. So. Pick a direction. Where would you want your nervous system to go? And then pick an object that goes with that.

• 1:21:08Tim Ferriss?

  I'll choose the sketchbook.

• 1:21:10Speaker 04

  Yeah.

• 1:21:11Tim Ferriss?

  Because that's where I am totally immersed in something present tense. I can get lost in artwork. I don't think about whatever mistake I made in the conversation yesterday. I don't think about whatever bullshit I have to handle tomorrow. I find that very nourishing in a calming way. So I'll choose that.

• 1:21:34Speaker 04

  And so as I'm watching you, I can see your eyes are kind of going somewhere. That's not anywhere in particular, which means you have like some images that are in your, in your mind.

• 1:21:43Tim Ferriss?

  Oh, maybe. I'm also looking at the sketchbook that's directly past the laptop.

• 1:21:47Speaker 04

  Okay. So maybe more generally.

• 1:21:49Tim Ferriss?

  But we can work with that.

• 1:21:50Speaker 04

  So maybe more generally, when you look at the sketchbook and you're talking about it and you're thinking about what it can do for you, like, what are you noticing that goes with that?

• 1:21:59Tim Ferriss?

  I would say my sympathetic nervous system seems to down-regulate. Breathing seems to slow a little bit. From being totally honest, I have like a small amount of anxiety because I was really consistent with my art for a while and I've lapsed for the last two months and I feel badly about it. Some level of guilt, but that's not what I'm going for.

• 1:22:19Speaker 04

  Yeah. So let me just pause there. So some kind of drop in your sympathetic nervous system. So how is that manifesting? You said your breathing's starting to calm down. What else is going with that? What are other ways that you're noticing?

• 1:22:33Tim Ferriss?

  Some muscular relaxation.

• 1:22:35Speaker 04

  Any particular area?

• 1:22:37Tim Ferriss?

  Yeah, back. Back, neck. Those would be most obvious, I would say. Less fidgety, less bouncing of the foot.

• 1:22:47Speaker 04

  And so as you're looking at this object, this sketchbook.

• 1:22:52Speaker 04

  And talking about it, you're noticing that you're having sympathetic activation is decreasing. It's changing your breathing. There's something happening in your back that's easing. And as I'm feeding this back to you, what are you noticing that goes with that?

• 1:23:06Tim Ferriss?

  I think it reinforces it. It's like, uh, it's not exactly positive reinforcement. It sounds like positive reinforcement for the relaxation. So I'm able to settle into it. I suppose.

• 1:23:17Speaker 04

  This is kind of like the beginning of scaffolding. This is what it's like.

• 1:23:21Tim Ferriss?

  Okay.

• 1:23:22Speaker 04

  Because if I try to say like, okay, you're going to focus on your breathing, or I'm going to give you an object to focus on. Fifty percent of people who are given the breath as an object of meditation find that it's not a safe object and it can actually induce anxiety. So if I have you pick the object, I couldn't have picked that in a million years. If I got to wander around your house and be like, which thing should I pick? I wouldn't have been able to pick something. You know, immediately you have so much going on. And as a meditator, you're able to like feel into your environment. And there's like, oh, wow, these different flavors of how they're, they're actually impacting me. And so I would spend an hour with you unpacking one particular object.

• 1:24:07Speaker 04

  And I would be watching how your hands are moving and you might be like, oh, and there is a story that goes with the sketchbook. And like, you might end up on who gave you the sketchbook and like, it's really about that. We kind of like go down this rabbit hole together and I'm tracking your physiology with mine. And if you're very, very dysregulated and dissociated and you're one of those people who can't feel anything anymore, I can notice very small changes in your physiology and be like, hey, you remember that? One thing that you just said, because I saw your eyes brighten up a little. I'll be able to like amplify, specifically amplify certain things. But I'm following your lead.

• 1:24:46Speaker 04

  And so as somebody who's been very traumatized about power dynamics and following any kind of instructions feels like oppression.

• 1:24:55Speaker 04

  And feeling trapped in sort of some system. If I'm following you and just reflecting back to you what I'm seeing, that can be a little bit more palatable. That's kind of what scaffolding is. And that's what we offer to meditators who have basically developed a trauma response to meditation itself, which can really rule out a lot of things.

• 1:25:21Tim Ferriss?

  A lot. Yeah, that's an elegant workaround slash approach. And I would say that I'm very fortunate that I don't personally, despite the childhood experience with the abuse, have that aversion to systems or coaches or teachers. I think in part because I'm such a problem student, in the sense that I just will constantly stop things and question things. And I don't feel like I need to take anything that is just off the rack, so to speak. So I feel very fortunate about that. Let me return, since I made a promise to my listeners and to myself that I would, to your personal practices. What does your self-care look like in that department? What are those practices?

• 1:26:06Tim Ferriss?

  Where have you landed?

• 1:26:07Speaker 04

  So I've been doing this resourcing for a long time, this scaffolding. And where it landed me, so I started to realize that I, this is in some ways not super surprising, but I have a very strong reaction to like living things, like animals and plants. And so I started to realize like how powerfully impacted my gardening. I started getting really obsessed with like rare plants and growing them in a grow light.

• 1:26:37Tim Ferriss?

  What kind of rare plants? Just can you name one? I'm so curious.

• 1:26:40Speaker 04

  Oh, just like, I don't know, weird tomatoes, things that you can't buy in the grocery store, just things that you can't find otherwise. But basically where I ended up was my husband and I bought 90 acres in an undisclosed mountain area in Vermont. And we built an off-grid cabin there. And it is so awesome that I think I'm going to move to Vermont.

• 1:27:06Speaker 04

  Oh, whoops. I just did it on like the Tim Ferriss podcast. But yeah, like this exercise that we just did, if that becomes the practice, replacing the hours a day that I did with Vipassana, with a practice like that, actually amplifying my positive engagement with the world and what's in it, that that grew into something so beautiful and magnificent as this place in the mountains. And so it's not just a technique that you do at your house to in order to perform better. It's just completely taken over my life. So that's where I ended up.

• 1:27:52Tim Ferriss?

  So it sounds almost epicurean in a way, right? Like tending the garden, engaging with nature.

• 1:27:59Speaker 04

  Sure.

• 1:27:59Tim Ferriss?

  And certainly, not to add the label to it, I'm just saying that, do you find that you derive the benefits you hope to derive from meditation through these new, this new engagement that you're referring to? Or have your goals just changed?

• 1:28:16Speaker 04

  If you wanted to paint a picture of like what my daily practice looks like, imagine, I'm wearing actually my plaid shirt, like sort of in commemoration of my Vermont self, but imagine me putting on like some Carhartt overalls and like getting a weed whacker chainsaw and going out and like doing trail work. And even for like the basic idea of coming back and having to do, you know, writing a paper or, you know, running statistics or something. Meditation never really improved my cognition. I always found that I was sort of one of those sleepy meditators. I would just get really, really, really calm and kind of like,

• 1:28:58Speaker 04

  my brain just kind of got dull. But if I go out there and just like use power tools outside in the cold, then I'm like, my blood's moving, my brain's working. That's doing more of what I was hoping meditation would do. And I'm also just like ecstatically happy, which meditation never did that for me.

• 1:29:18Tim Ferriss?

  Humans are built for movement. You gotta move. The meditation's great, but it's for me very valuable. So I will say that small dose, high frequency, high meaning twice a day, is very strengthening to my life and my experiences. And I spend four to five times minimum as much time moving every day. The movement, the movement is a critical piece of things. Where can people find more information with respect to a class or training related to the meditation-related adverse effects, preventing them, mitigating them, recovering

• 1:30:00Tim Ferriss?

  from them, whether it's as an individual or a facilitator/trainer?

• 1:30:05Speaker 04

  The public-facing service branch, info branch of my lab is at cheetahhouse. So that's cheetah, like the animal, house, like a house.org. And there's tons of information on the website, lots of videos and links to different kinds of symptom-specific resources. But if you're interested in training specifically on the cheetahhouse website, there's a tab called "Online Courses." If you're a meditation teacher or a clinician, you can actually take the courses. And there's a quiz, and it will give you, you know, you can make sure that you know the content. So there's more information there. You can also sign

• 1:30:48Speaker 04

  up for the cheetahhouse newsletter, and that will alert you to any of the kind of public lectures that we have. We have one a month, and actually, we have one today that's on CERT, which is Spiritual, Existential, Religious, and Theological Issues in Psychedelic-Assisted Therapies by Roman Politsky. So that's a good one to see today. He just published an article in JAMA about that topic, and he'll be unpacking it for people. So we do meditation-related challenges, meditation-related issues, but also psychedelics are becoming much more of a topic. It's unavoidable that those, meditation and psychedelics are combining.

• 1:31:31Tim Ferriss?

  Yeah, absolutely. And, you know, I want to zoom out for just a quick second and say that, well, actually, let me volunteer something I don't think I've said publicly, which is, we've been talking about, among other things, these adverse events, adverse effects that can be associated with meditation, different types, different volumes, and psychedelics. However, I don't want to lose what I mentioned earlier. I may have gotten the the boundaries, the upper and lower bounds, wrong on the numbers, but adverse events in psychotherapy. After my experience at Spirit Rock, I went to one of the most famous psychotherapists who works with trauma in the world. And if I mentioned his book, everyone would recognize

• 1:32:16Tim Ferriss?

  it, who's in the trade, per se. And this guy was one of the most narcissistic, unbelievably unempathetic people I'd ever met in my life. And he did a tremendous amount of damage. I met with him twice for two individual sessions. And his ego is so out of control, and his sort of recommendations so intense and so flippant, that it did a tremendous amount of damage. And that took, this was related to the childhood sexual abuse, and it took a long time to undo the damage inflicted by a famous psychotherapist. And I guess I wanted to bring this up to say that when you engage with these mind-altering modalities,

• 1:33:01Tim Ferriss?

  whether or consciousness-altering modalities, assume that you're dealing with power tools and you need people who will admit that, yes, you can cut fingers off if you use power tools incorrectly, and furthermore, who have lots of time, not just working with clients, but handling adverse events. And handling them is not just an issue of capability, it's also an issue of empathy and will. So Danny Meyer, who's famous for Shake Shack and Hospitality, and many different restaurants, Gramercy Tavern and others, has this sort of matrix on the wall for employees, and it's the Will Can Matrix, right? So just because someone is a skilled psychotherapist... Does not mean they're going to be willing to provide aftercare or a safety net.

• 1:33:46Tim Ferriss?

  If you have an unraveling, it's to me really important that you sort of assess practitioners in advance to ensure that they have in fact handled these cases and feel very capable and have demonstrated competency in handling these things calmly. So I just want to say that because there's so many fly by night rent a shamans running around and people who have done like one yoga retreat and had one or two psychedelic experiences who are suddenly acting as on the road messias trying to proselytize everyone. And this also goes for meditation, right? Like I know people who have basically had what I would call psychotic breaks pursuing Kundalini awakening and then they're suddenly traveling salespeople for endorsing this and they haven't yet even

• 1:34:30Tim Ferriss?

  achieved stability for themselves. This is really common. So just make sure you're dealing with people who have handled red line casins and have a clear demonstrated track record regardless of the modality. Is there anything you'd like to add, not necessarily along those lines, but any comments you'd like to make? I have more questions. I do want to ask about NDEs.

• 1:34:52Speaker 04

  Oh, I forgot about that part of my life.

• 1:34:55Tim Ferriss?

  Oh, I know. I take notes so I don't forget.

• 1:34:58Speaker 04

  I mean, one of the things that we've learned at Cheetah House is that exactly that scenario that you're describing is that the helper professions can also be the source of harm and trauma. This is called institutional betrayal when the people who are supposed to be helping you are actually the cause of harm. What happens when you when you have not only trauma to meditation, but trauma to all helping professions and helping professionals, it like really restricts your your options. And so, you know, we and there's other groups that do this too. You know, we run a peer support model because a lot of people get to the point where they don't trust anyone

• 1:35:39Speaker 04

  until they can sort of prove that I was completely undone by this. I understand what it's like to be leveled by this scenario. And then you're like, okay, you get it. Now I can talk to you because that empathy, when you've been leveled that much, this is like one of the silver linings, is that you have so much compassion and empathy.

• 1:36:06Speaker 04

  When you've been leveled, you really understand what that's like to be in that place, to be a puddle on the ground. So that's one of the models that we have at Cheetah House, and I think it really works. It works in two ways. One is that people feel heard and validated and not alone, because they're being able to talk to someone that this happened to as well, who's also recovered. So they're like, oh, my God, I can actually recover from this. And then for the people who are offering care, you know, they're like, wow, I had this five-year hole in my life that was just this thing that is not good for anything. And now I can actually, it's something that's actually a gift I can give to somebody

• 1:36:47Speaker 04

  else. And so every moment that they spend with someone else is actually sort of being fueled by that trauma. So it's nice to be able to have that trauma mean something and be useful in some way and not just be a drain on your life. So that's another piece that I think is a nice model that's out there. But yeah, I hear you with the trouble finding a good therapist. Boy, yeah.

• 1:37:10Tim Ferriss?

  Yeah, a lot of clowns running around all over the place. And just to underscore the peer support, because you reminded me of something. I'll put out a plea to the psychedelic communities, which is, if you have not, this is also related to your getting leveled comment, if you have not had at least 30 to 50 high-dose psychedelic experiences, you should not be serving psychedelics to anyone. That'll be statement number one. That would be a minimum. And I'm not recommending people do anything illegal, but I'm simply saying people are going to do what people are going to do. If you have not been tumbled and humbled in a way that has left you questioning whether you should ever touch these compounds again,

• 1:37:53Tim Ferriss?

  you are not in a position to administer to other people. And the equivalent would be if you go skiing once on the bunny slope and you happen not to fall, and all of a sudden, you're taking people on hell skiing trips without any type of guides or airbags, because skiing is fun and helpful. That is what I see all over the place. So step number one is 30 to 50 minimum, personally.

• 1:38:17Tim Ferriss?

  Because that'll give you a chance to go skiing 50 times. And not only will you fall, you will have some bad falls and you'll have different types of falls and then you'll be more informed on a subjective level about the risks involved. And then I would say, secondly, you should, and this connects to your peer support comment, volunteer with an organization like Zendo at festivals where the age range skews younger, like Lightning in a Bottle and other places. Zendo is peer-driven harm reduction related to psychedelic, but really drug consumption. And you get a decent amount of training. It's pretty nominal.

• 1:38:57Tim Ferriss?

  It's non-directive support. So you're not trying to therapize people. But here's what I would suggest is you volunteer for the roughest shift, which is generally going to be after midnight. And if you're capable, and you should determine if you're capable, volunteer what they sometimes call the crisis tent, which is when they have red line cases, when people are really freaking the fuck out and losing their minds, often for hours at a time, and see how well you handle those. If you don't handle those really well, you should not be serving psychedelics to anyone. So that's my public service announcement. Anyway, NDEs, how did you become interested in near-death experiences?

• 1:39:39Speaker 04

  Wow. This was not a question that I-

• 1:39:42Tim Ferriss?

  I'm deeply interested in this.

• 1:39:43Speaker 04

  I was like, I wonder what part of my website he's gonna find, discover. I totally forgot about this. I mean, I think, wow, this is a really long time ago, but I was really interested in temporal lobe epilepsy and how people have religious experiences as a result. They call it the sacred disease. And there's been speculation that there've been a number of saints that had temporal lobe epilepsy. And so- I was really interested to know whether near death experiences, well, I was just really interested in the question of whether religious experiences and temporal lobe epilepsy, if there was an overlap. But near death experiences are actually one of the few types of spiritual

• 1:40:28Speaker 04

  experiences that are actually kind of similar. There's a typography, like there's a tunnel, there's a light, there's a life review. They're kind of similar. And so that's kind of an ideal thing to study. And so that's what I did. And I happened to work in a sleep lab and sleep is a natural activator of hypersynchrony. So basically epileptiform brain activity, because as you go to sleep, your brain synchronizes. And so if you tend to have epilepsy, it will show up in your sleep. You can also use stroblights.

• 1:41:01Tim Ferriss?

  To induce epilepsy?

• 1:41:03Speaker 04

  Yeah.

• 1:41:03Tim Ferriss?

  Do you mean? Hence the warnings on all the video games.

• 1:41:06Speaker 04

  Right. But from, you know, an institutional review board, human subjects, you know, feel like I'm going to induce seizures in people. So, but like, hey, I'm not doing any induction. I'm just, they're just sleeping. I don't have to tell them that. So anyway, they slept in the lab and we looked at their brains to see whether they had any kind of hypersynchrony. And they did. That was the shocker.

• 1:41:29Tim Ferriss?

  Wait, when you say they, these are people with diagnosed epilepsy, you're talking about people who had NDEs?

• 1:41:34Speaker 04

  I taught a class on death and loss in graduate school. And as part of that class, one of the people, I kind of inherited a lot of the guest speakers from like other people that taught the class. And one of them was a woman who had had a near death experience and ran a near death experience support group. And I was like, amazing. So I went, started going to the support group and I was like, there's so many of them. And then I was like, hey, you guys, you want to come sleep in the lab and we'll scan your brains and see what's going on there. And so I kind of made friends with the near death support group. And that's how that study happened. So the group was, I forget how many there were, but I don't know, like 20 or something like people who had had near death experiences. And then we

• 1:42:16Speaker 04

  had people who had some type of non near death experience control group. I forget if they were trauma survivors. I can't even remember.

• 1:42:25Tim Ferriss?

  Far death experience?

• 1:42:26Speaker 04

  Yeah. Anyway, we had a control group and they did not have any kind of epileptic form activity in their brains.

• 1:42:33Tim Ferriss?

  How do you explain that? That's so fascinating.

• 1:42:36Speaker 04

  I'm pretty agnostic as to what that means.

• 1:42:39Tim Ferriss?

  Yeah, but just if you're like two drinks in and speculating.

• 1:42:42Speaker 04

  There's two possibilities. One is that they did not have epileptic form activity and it's a scar. It's like a residue of the experience. Chances are when you have a near death experience, and these are people that all had their heart stop, so they definitely had some anoxia oxygen deprivation, which can cause hypersynchrony and epileptic form activity. So that's one possibility. The other possibility is that they had a sort of tendency towards hypersynchrony and that was what caused the experience. But you know, I was very agnostic about not choosing a position or having an interpretation. I just said, this group has a sort of distinct brain activity compared to non experiencers. And I just left it at that. But what was

• 1:43:27Speaker 04

  so interesting was the response that I got from both complete skeptics and from the near death experience community. So I got the total opposite from no interpretation on my part. And this has been actually like a kind of thing that's followed me for my whole life.

• 1:43:45Tim Ferriss?

  The universe Rorschach test. Let's see how people take it.

• 1:43:49Speaker 04

  Thank you so much for verifying and proving scientifically with neuroscience, because neuroscience can prove anything, right? That heaven exists. You know, and I'm like, well, I don't think I really did that, but thanks.

• 1:44:02Tim Ferriss?

  I'm not sure that was in my summary.

• 1:44:04Speaker 04

  And then the skeptics would write me and be like, thank you for finally proving that these people are all nuts. You know, and I was like, okay, I didn't either of those things, but that's interesting. And so, wow, I mean, that's a whole other like conversation is be a researcher or just talk about charged topics and see what kind of responses you get.

• 1:44:25Tim Ferriss?

  Fascinating. I could keep going on the ideas. I have a lot of questions about that. A lot of the descriptions seem to be incredibly similar to the mystical experiences reported by.

• 1:44:40Tim Ferriss?

  Users of higher dose psychedelics. The descriptions are very, very similar, which is interesting because you have this sort of fear extinguishing related to death in both camps frequently, it seems to be the case. And I'll ask you a question, we can cut it out of the audio if you want, but I'm curious. So there seem to be, and I don't think there's anything in any peer reviewed studies or anything, but many case studies of supposedly reports of people who observe things while their hearts are stopped, or they are technically brain dead. So conversations that are happening, things that are moving around, the tools that are

• 1:45:23Tim Ferriss?

  used, they take the dentures out of someone and put them on a specific tray, these types of things. Is that just complete nonsense? Or do you think that's something that's worth investigating? Piques my curiosity.

• 1:45:37Speaker 04

  It's funny because I have the reputation for being the grumpiest skeptic ever. And now I'm going to tell you some mind blowing stories from my near death experience research. What are you trying to do to my reputation here, Tim?

• 1:45:48Tim Ferriss?

  We don't have to keep it, but I think, I know people will be interested in, I'm interested, I have to follow my own.

• 1:45:53Speaker 04

  I'll tell you a crazy story that happened. This is true, and it happened, like the, the sort of end of the story happened recently. I'll tell you the end of the story first. So we want to move to Vermont and we're building another off grid cabin. So we're like interviewing builders. And so we went walking around, we met this builder and we were walking around this other house that he built. And he's just showing, you know, he's showing us all the features of this house. And one of the features was a double pane glass that you can just like flip the switch and there's an opaque gas. Maybe you have one of those.

• 1:46:26Tim Ferriss?

  No, I don't have one, but I know the windows you're talking about.

• 1:46:28Speaker 04

  And I was like, that's so awesome. Suddenly this window goes, you know, opaque and it's like kind of foggy. And that reminded me of this experience that this woman had in my study. She was actually a survivor of a World War II bombing in London. So it was a very long time ago. First of all, she came back speaking another language from her near death experience. So that was the first weird thing. So I was like, you know, all of these stories, and I was like a graduate student and all of these stories were very far fetched to me.

• 1:47:04Tim Ferriss?

  And this was a language she had not been exposed to?

• 1:47:06Speaker 04

  I don't know.

• 1:47:07Tim Ferriss?

  Okay, she came back speaking another language.

• 1:47:09Speaker 04

  Yeah, I wasn't paying that much attention. Their stories were kind of, we didn't, we never published their stories, but I have them.

• 1:47:16Tim Ferriss?

  Okay, Kathy.

• 1:47:16Speaker 04

  Yeah, I was like, okay, let's see what you're going on in your brain. But she told me this story about some near-death experiencers have, a lot of them have life reviews, where they go through their lives and they kind of experience the consequences of their actions from the perspective of who they impacted, which can be very hellish, depending on what kind of person you've been. But then, if people are sort of dead long enough, they also have flash forwards, where they actually not only see their past, but also the future. So this was one of the ones that was a flash forward. And so she told me that she basically saw this city, and all the buildings were basically

• 1:47:58Speaker 04

  made of this glass that had, and this is a woman, she's probably like 80 at this time, she's not super like technologically sophisticated, and she's describing this glass that when you flip a switch, you can turn it, it has some kind of gas in between it, that you can flip the switch and it turns into opaque, and that the future will be this glass. And I was like, whatever, okay, that's so crazy sounding. And then, maybe like four years later, she called me and she was like, the glass exists. And she sent me to like a Scientific American or like Discover magazine, and it was like Smart Glass, I think it's called. She's like, this isn't the exact company, so don't like invest in it or anything, but

• 1:48:40Speaker 04

  like this is, this is the precursor to what it's going to be. She's like, this is the future of what things are going to be made out of. So again, completely sealed off that part of my life for like, I don't know, 25 years, 23 years, and now I just saw the glass myself.

• 1:49:01Tim Ferriss?

  In Vermont.

  So, I don't know, people think I'm super grumpy and skeptical, but like, I'm just agnostic, I don't know. I think just letting the mystery be there is, is fine. It just doesn't need to be solved. I have heard crazy stories like that, I don't know what to make of it. Will I be investing in Smart Glass? Maybe, I mean, can't hurt, right?

• 1:49:27Tim Ferriss?

  I mean, it could hurt depending on how much you invest.

• 1:49:29Speaker 04

  Right.

• 1:49:29Tim Ferriss?

  But a little bit, a little bit, a little bit might go a long way if they're going to build cities out of it. It's amazing. You know, there's part of me that with no defensible foundation, well, I'll leave that alone for a second, but feels like some of these NDEs, the high dose, or they don't even need to be high dose, but let's just say higher dose psychedelic experiences and many other things, some of these meditative states are kind of touching parts of the same thing. It's like the five blind men holding on to different parts of the elephant, that whole parable. But anyway, working pet theory with, without a whole hell of a lot to back it up that would stand up to the capital S kind of skeptic societies and so on.

• 1:50:14Tim Ferriss?

  But still, something that sticks in my mind. Well, Dr. Britton, this has been great. I've really enjoyed this conversation. I think it will be helpful to people and to many who are listening, probably who have had some of these adverse events or effects who have felt very much alone. And certainly I could have used that feeling when I was going through what I went through at my meditation retreat. Is there anything else that you would like to add? People can find Cheetah House on Twitter, at Cheetah House org, on Facebook, Cheetah House dot org, and Instagram, Cheetah dot house. Anything that you'd like to add before we wind to a close?

• 1:50:56Speaker 04

  I mean, I think that I'd like to end just by thanking you for being as open and forthcoming as you have been. I don't know if you've gotten any pushback, but a number of people who share their negative experiences, any kind of negative experience, but particularly ones with meditation, get a lot of kickback and it's not an easy thing to do. So I'm very appreciative that you've done that and you didn't have to. So I think it's going to be really helpful for people and, you know, especially this kind of group of people that emulate you and these sort of young male 18 to 30 demographic. So, you know, you're really, in my world, you're, you know, really a hero and doing

• 1:51:41Speaker 04

  something that's hard. And just so, I just want to say thank you.

• 1:51:46Tim Ferriss?

  Thank you. I really appreciate you saying that. And it's my pleasure to do it because by offering my story, I'm not saying meditation bad. I actually find meditation in small doses to be incredibly, incredibly helpful in my life. And that is not mutually exclusive with also saying, hey, in different formats and different doses, things can go off the rails and you need to, being a good boy or girl scout, be prepared for that. And institutions and groups and facilitators and centers need to be prepared for that. And hope is not a strategy. It's like you get in your car and drive with the seatbelt off. It's like, that's just stupid. It's like, maybe you haven't had a head-on collision, but they happen every day.

• 1:52:31Tim Ferriss?

  So where a seatbelt? I mean, they're basic precautions and I hope that will help people to think about this in a sort of risk-informed way. Not so that they can say, "I'm never going to meditate," but simply to know this is a possibility and to ensure that they have support structures around to help them in case they run into turbulence or something even more extreme as I did. And that's true for so many things in life. And I really appreciate you doing the research you do. I'm sure you get a hell of a lot of flack for it. And it's important to have this be part of the conversation. And it's going to increasingly be part of the conversation.

• 1:53:13Tim Ferriss?

  I mean, you have startups and companies that are worth billions of dollars promoting mindfulness and meditation. You have the same thing happening in psychedelics, lots of profit motives, which is not automatically something that begets evil, but it does beget incentives. And that means we will most certainly have tens of thousands, potentially hundreds of thousands and millions of people engaging with things that historically were pretty limited to a fine slice of the population. And we are going to see adverse events. You know what? I promised one other thing that I have to ask about. So how did the Dalai Lama receive your description of your research?

• 1:53:59Speaker 04

  Oh, boy. Did you see, did you watch the video?

• 1:54:03Tim Ferriss?

  No, I didn't see the video. I saw some text about it.

• 1:54:05Speaker 04

  Okay, so there is a video of me presenting to the Dalai Lama as part of the Mind and Life Dialogues. I will let viewers make their own decisions about what they think. I will tell you some feedback that I got. I mean, you'll see me there if you want to watch Willoughby in sympathetic overload. It was a pretty terrifying experience in general. So I don't really remember the feedback as it was happening because I was a little bit like out of my body, probably. But there were a lot of people there. The entire Mind and Life Board was there. And so they gave me some feedback. A lot of people found his response fairly dismissive and also a bit,

• 1:54:48Speaker 04

  not particularly compassionate. Like, he was laughing half the time. And I was like, well, did I tell you that the duration of impairment was three years? And also, the people that it happened to were some of our best and brightest meditation teachers. Name any meditation teacher that you can name who's written Dharma books. He was probably in our study and he probably had a meditation-related challenge. And the Dalai Lama was basically saying that this happened to people because they didn't have enough Buddhist training. So, I don't know, you're not really supposed to talk shit about the Dalai Lama, so you might want to cut this one out, but...

• 1:55:27Tim Ferriss?

  People need to grow up.

• 1:55:28Speaker 04

  I wasn't particularly impressed, if you're allowed to say that. Yeah.

• 1:55:33Tim Ferriss?

  No, it's fine. Like, I just think people need to grow up. It's like, if you have externalized your agency into someone you view as a god, you're setting yourself up for trouble. And I think, like, I'm not a Dalai Lama expert. I'm sure that he has and demonstrably has offered a lot to the world, but it doesn't mean he's infallible.

• 1:55:51Speaker 04

  This is also, my husband was like, he's the Dalai Lama. He was brought up from like age zero until however old he is now, like to defend Buddhism. What do you expect? So I think that's a pretty good answer. And also, it's very emblematic of, it's possible that certain teachers have never heard of any problems, because why would you tell them that? You never want to be the one that's like failing the practice that they're giving you, or telling them that the practice that they gave you is harming you. Like, that would, that's just not even like a possibility. So, yeah, it is what it is. I left it up there as sort of a historical marker, but I didn't refer you to it, because

• 1:56:35Speaker 04

  it's kind of a mixed bag.

• 1:56:37Tim Ferriss?

  All right. So, boys and girls out there, be safe, measure twice, cut once. And thank you, Willoughby, so much for the time. I really have enjoyed this. I think it will be valuable for people. And at the very least, it's going to spark conversation. So I'm going to get a ton of shit. I'm fine with it, because I think this is important. And for people listening, you'll find links to everything, the resources we've mentioned, any books, et cetera, people, and so on, in the show notes, as per usual, at tim.blog/podcast. And until next time, be a little kinder than is necessary, not just to others, but to yourself. I'll quote Jack Kornfield, actually, which, and I'm going to paraphrase here, but if

• 1:57:22Tim Ferriss?

  your compassion does not include yourself, then it is incomplete. And part of being compassionate, now this is my voice, is making sure you account for risks, and not live in fear, but certainly live informed. So until next time, everyone, thank you for tuning in.

• 1:57:40Tim Ferriss?

More than 80% of Americans, that's probably a lot of you listening, including me, because I do measure my omega threes, do not get enough omega three fats from their diet.

• 1:59:04Tim Ferriss?

  That is a problem because the body cannot produce omega threes, an important nutrient for cell structure and function. Nordic Naturals solves that problem with their doctor recommended, and in fact, this brand was recommended to me by one of my doctors, Ultimate Omega Fish Oil Formula. So the ultimate omega fish oil formula for heart health, brain function, immune support and more. It's incredibly pure and fresh with no fishy aftertaste. So I have been taking Ultimate Omega for the last two months or so. And this fishy aftertaste issue has been a problem for me and it's actually with other brands induced some nausea after a few days. And Ultimate Omega has been as clean as a whistle. I've had no issues whatsoever.

• 1:59:47Tim Ferriss?

  And if you are vegetarian or prefer to alternate, I ended up alternating two products. And that is number one, the Ultimate Omega Fish Oil Formula and also the Algae Omega, which is plant-based EPA and DHA. That's also from Nordic Naturals. So I ended up getting both of those products and it has improved my recovery from workouts. It's improved my sleep. It has improved my mood and I know that because I pulled out a lot of other variables. In any case, back to the read.

  This episode is brought to you by Eight Sleep. Temperature is one of the main causes of poor sleep and heat is my personal nemesis. I've suffered for decades tossing and turning, throwing blankets off, pulling the back on, putting one leg on top and repeating all of that ad nauseam. But now I am falling asleep in record time. Why? Because I'm using a device that was recommended to me by friends called the Pod Cover by Eight Sleep. The Pod Cover fits on any mattress and allows you to adjust the temperature of your sleeping environment, providing the optimal temperature that gets you the best night's sleep. With the Pod Cover's dual zone temperature control, you and your partner can set your size of the bed to as cool as 55 degrees or as hot as 110 degrees.

• 2:02:06Tim Ferriss?

  I think generally in my experience, my partners prefer the high side and I like to sleep very, very cool. So stop fighting, this helps. Based on your biometrics, environment and sleep stages, the Pod Cover makes temperature adjustments throughout the night that limit wake-ups. and increase your percentage of deep sleep. In addition to its best-in-class temperature regulation, the Pod Cover sensors also track your health and sleep metrics without the need to use a wearable. Until November 30th, my listeners can save $350 on the Pod Cover. Go to 8sleep.com/Tim, all spelled out. That's 8sleep.com/Tim for these exclusive holiday savings.
