Here’s a thought that makes a lot of modern Buddhists squirm: what if some of the great visionary texts of the tradition weren’t written by sober monks sitting under trees, but by practitioners who’d just drunk a cup of something very, very strong? That’s the uncomfortable, fascinating question raised by scholar and longtime Tibetan Buddhist practitioner Mike Crowley — and the deeper you follow the thread, the harder it is to dismiss. His research into a mysterious elixir called amrita reopens an old debate about psychedelics, master plants, and the roots of contemplative practice.

For readers who found their way here while researching retreats, ceremonies, or the overlap between meditation and plant medicine, this story matters. It reframes a question many people quietly carry into their first psilocybin or ayahuasca ceremony: am I cheating by using a substance to reach what the mystics reached? The historical record, it turns out, is messier and more interesting than the sanitized version most of us were handed.

The Monk Who Kept Tripping

Crowley’s story starts the way a lot of these stories start — with LSD in the 1960s, back when it was still legal and still being passed around by curious young seekers. During one trip, he had an experience he couldn’t quite explain. Later, reading translations of classical Buddhist masters, he kept running into descriptions that matched what he’d felt almost line for line.

Two possibilities, he figured. Either the acid had briefly handed him something that only decades of monastic practice were supposed to unlock. Or — and this is the one that stuck with him — the old masters had been doing something similar. Something chemical. Something they weren’t especially eager to spell out for later generations.

He didn’t drop the question. He went on to study with a Tibetan lama for more than twenty years, eventually becoming one himself, while quietly continuing to work with psychedelics on the side. The result, after decades of textual digging, is his book Secret Drugs of Buddhism — now in its second edition and, in his telling, a long-overdue correction to the story.

What Was Amrita, Really?

Scattered through Vajrayana and Tantric Buddhist texts is a word that keeps surfacing: amrita. It translates roughly as “deathless” or “nectar,” and depending on which scholar you ask, it was anything from a symbolic metaphor to a very real psychoactive brew consumed during sacramental rituals in medieval Buddhist communities.

Crowley sits firmly in the “very real” camp. He argues that amrita was potent enough to blur the line between ordinary mind and awakened mind — the exact territory serious meditators spend lifetimes trying to reach. The question is what it was made of. Candidates floated by various researchers include:

• Cannabis preparations, which have a long documented history across South Asia
• Ephedra, the stimulating desert plant also linked to the Vedic soma debate
• Syrian rue and other MAOI-containing plants
• Psilocybe cubensis — the magic mushroom familiar to most modern psychonauts

Crowley’s money is on the mushrooms. His case leans on iconography as much as text. The curious bump on the Buddha’s crown, he points out, bears a striking resemblance to the umbo — the small raised nipple on the cap of certain Psilocybe species. In Tantric art, water buffaloes keep showing up in strange symbolic contexts, which he connects to Panaeolus cambodginiensis, a psychedelic mushroom known to grow on buffalo dung in parts of Southeast Asia. Coincidence? Maybe. But once you start seeing it, it’s hard to unsee.

Doesn’t Buddhism Forbid Intoxicants?

This is where most people stop the conversation. The famous fifth precept — one of the five ethical vows a lay Buddhist typically takes — is usually translated as abstaining from intoxicants that cloud the mind. Case closed, right?

Not quite. Crowley points out that translation is doing a lot of work there. He took his own vows in Tibetan, and in the Tibetan rendering, the only substance explicitly named is chaang — a local barley beer. “That’s the only thing I actually vowed to abstain from,” he jokes. The sweeping “anything psychoactive” reading is a later interpretive layer, not a universal mandate baked into the earliest texts.

Whether you buy that argument or not, it’s a useful reminder: the clean, austere version of Buddhism exported to the West in the twentieth century was curated. Earlier Tantric and Vajrayana traditions were considerably weirder, wetter, and more experimental than the yoga-studio version suggests. Ritual substances, sexual yoga, charnel-ground practices — all of it was in play, and much of it got quietly swept under the rug on the way to becoming respectable.

Why This Matters If You’re Considering a Psychedelic Retreat

Fair question: why should a 21st-century person weighing a trip to Peru or Jamaica care what medieval Buddhists were drinking? Because the question underneath Crowley’s research is the same one anyone sitting down with ayahuasca, psilocybin, or San Pedro eventually bumps into. Is a chemically induced insight a real insight? Or is it a shortcut that cheapens the thing?

Crowley’s answer is interesting precisely because he’s been on both sides of the fence for fifty-plus years. His view: psychedelics can genuinely show you the nature of mind — that’s what he thinks the old masters understood. But a glimpse is not the same as a life. Insight without integration tends to fade. The vision at hour three of a ceremony becomes a vague memory by the next full moon unless something anchors it.

What anchors it, in his experience, is daily practice. Meditation. Ethical choices. A community of people who can tell you when you’re fooling yourself. He uses psychedelics only a couple of times a year, and credits the sitting cushion with doing the heavier lifting the rest of the time. That’s a useful frame for anyone shopping around for a retreat — the ceremony is the opening, not the whole house.

What To Take From This If You’re Researching a Retreat

If you’re in the research phase — reading everything you can find, trying to figure out whether to actually book something — here’s what I’d pull out of this history for practical use:

1. Be skeptical of “pure” traditions. Almost every contemplative tradition has a secret drawer where the plant medicine lives. Buddhism, Hinduism, early Christianity, Mesoamerican religion, Amazonian shamanism — the overlap between master plants and mysticism is the rule, not the exception.
2. Don’t treat the ceremony as the destination. If a retreat sells itself purely on the intensity of the trip and says almost nothing about preparation, integration, and aftercare, that’s a yellow flag. The trip is the easy part.
3. Ask what the facilitators do when they’re not pouring medicine. Reputable guides tend to have their own ongoing contemplative practice — meditation, prayer, long apprenticeships with elders. People without one often turn out to be charismatic improvisers, which is riskier than it sounds.
4. Give yourself a frame. You don’t need to become a Buddhist to benefit from psychedelics, but having some structure — a daily sit, a journal, a therapist, a trusted friend — makes the difference between a wild memory and a changed life.
5. Go in with questions, not expectations. The visions, whatever they are, respond better to curiosity than to a demand that they fix your addiction, your marriage, or your career by Tuesday.

The Longer View

There’s something quietly reassuring about Crowley’s thesis, whether or not every detail holds up to scholarly scrutiny. The idea that human beings have been drinking strange brews, sitting with the results, and arguing about what they meant for thousands of years — that puts the current psychedelic moment in perspective. We’re not inventing something. We’re rediscovering, badly and clumsily and sometimes beautifully, something our ancestors already knew.

It also softens the modern binary that treats meditation and psychedelics as rival sports. In Crowley’s telling, they were never meant to be rivals. They were tools in the same workshop, used by people who understood that insight is cheap and transformation is expensive, and that you probably need both the lightning strike and the long slow walk home.
