The Impossible Country

Every good expedition needs a first witness, and ours is not an oilman or a psychologist. She is a French opera singer. Alexandra David-Néel sang leading roles in Hanoi and Athens, wrote anarchist tracts, studied Sanskrit — and then, in her forties, walked away from Europe into the Himalayas and stayed for fourteen years. In 1924, aged fifty-five, she slipped into Lhasa disguised as a beggar-pilgrim, her face darkened with soot, becoming the first European woman ever to reach the forbidden city.

When she came home she published Magic and Mystery in Tibet (1929), and with it handed the West its entire vocabulary of lama superpowers. Nearly every impossible thing anyone has chased in these mountains since traces back to her pages. The inner heat — tummo — that lets monks sit in wet sheets on frozen ground and steam them dry; she claimed she practiced it herself to survive the passes. The lung-gom-pa, the trance runner she says she watched through field glasses, bounding across the plateau like a man made of springs, forbidden to be interrupted mid-stride. And the strangest of all: the tulpa, a being built out of nothing but disciplined concentration. She said she made one — a plump, jolly little monk — and that over the months he grew lean, sly, autonomous, and so hard to get rid of that dissolving him took half a year of deliberate mental work.

Hold on to all three claims. Each one goes under the lamp before we reach the summit. And notice, as we set off, why she's the right guide to start with: she was neither a debunker nor a devotee. She reported what she saw, tried what she could on her own body, and offered natural explanations wherever she found them — including for her own monk, whom she was inclined to call a creature of suggestion. That posture — this sounds impossible; good; let's look closely — is the thread that ties this whole century together.

Slick came down from the Yeti hunt asking stranger questions than he'd carried up. The scientist P. N. Rao, who knew him, remembered being grilled about healers in India who treated snakebite with chanting, and about whether reincarnation could be put to a test. His niece and biographer Catherine Nixon Cooke describes the lamas who impressed him most: men who seemed to raise and lower their body temperature at will, who rose from the lotus posture, who moved objects without touching them.

So here is the full catalog — David-Néel's wonders and Slick's, gathered in one place, each written the way a believer would tell it. And each with a button. Press it, and the legend meets the published record.

Of everything in the book of wonders, this is the claim that came true — and I want you to feel how strange that is. David-Néel described novices tested on winter nights by draping them in sheets dipped through lake ice: dry the sheet with your body, repeat till dawn. For fifty years that sat in the same folder as levitation. Then in 1981 the Harvard cardiologist Herbert Benson traveled to Upper Dharamsala — with the Dalai Lama personally helping to open doors that monks had kept shut to outsiders for centuries — and put thermometers on three practitioners of g-tummo, the inner-heat yoga.

The result ran in Nature the following year: finger and toe temperatures rising as much as 8.3 °C at will, on command, while they meditated. Not core temperature — that would be lethal — but a huge, voluntary opening of peripheral circulation that ordinary physiology says you don't get to control. Thirty years later, Maria Kozhevnikov's team went back with EEG and better thermometers and found expert practitioners driving armpit temperature into the mild-fever range, 38.3 °C, using forceful "vase breathing" — an isometric furnace of clamped abdominal muscle and held breath — apparently sustained by the meditative visualization of flame. The legend said mind over heat. The truth is breath and muscle doing the burning, and mind holding the door open. Try it yourself:

If you retell one story from this whole mountain at a dinner party, make it this one. And tell it the way I'm about to — with the doubt left in — because the doubt is what makes it great.

In 1967 Richard Alpert — the Harvard psychologist fired alongside Timothy Leary — arrived in the Kumaon foothills carrying a supply of LSD, hoping to find someone in India who understood these substances better than the West did. At a small ashram at Kainchi he met Neem Karoli Baba, the blanket-wrapped guru his devotees called Maharaj-ji. Almost immediately, by Alpert's account, the old man asked him for the "yogi medicine."

Alpert handed him one tablet of very pure LSD — 305 micrograms, several times a full dose. The guru beckoned for more. Then more. Nine hundred and fifteen micrograms, swallowed all at once — an amount that would dismantle anyone's ordinary consciousness for the better part of a day. Alpert sat and watched. In Be Here Now he described the outcome: "every now and then he twinkles at me and nothing — nothing happens!" Alpert came home as Ram Dass, and the acid-gobbling guru became a founding legend of the American spiritual counterculture: the man for whom the drug was redundant, because he already lived where it pointed.

The story has a second act that is less famous and better. In 1971 Ram Dass returned, privately nursing the obvious doubt — had the old man palmed the pills? Maharaj-ji raised the subject himself. Did you give me medicine? Did I take it? Did it work? Then he asked for it again, and this time took roughly 1,200 micrograms while Ram Dass watched closely. Partway through he feigned going mad for a moment — a joke at his visitor's expense — then returned to normal and asked whether there was anything stronger. Afterward came the teaching his devotees still repeat: such medicines were known to the yogis of the Kullu Valley long ago, and used with fasting and preparation; they are useful, but they are a visit, not a residence. As the devotee tradition renders it: "love is a stronger medicine than LSD."

And then — this is the part a historian has to respect — the story survived an execution attempt. In 1999 Terence McKenna told the science writer John Horgan he suspected sleight of hand; of the holy men he'd met in his own travels he said, "I saw outrageous shenanigans." In 2001 Paul Krassner published in High Times that Ram Dass had admitted inventing the whole episode. Horgan picked up the phone. Ram Dass, frail after his stroke, insisted the story was true and that he had never recanted to anyone. Krassner's claim traced back to something he thought the psychologist Stanley Krippner had told him; Krippner denied saying it; Krassner retracted and apologized in print. The debunking, it turned out, was the fabrication. Ram Dass stood by the account until his death in December 2019.

None of which makes it true. There was no verified dose in the guru's bloodstream, no controlled observation, and a room full of people who longed to believe. It only makes it undebunked — which, for a fifty-year-old miracle story, is itself unusual.

Fifty-nine years after Kainchi, the experiment ran again — uninvited, on camera, with a different molecule. The filmmaker Dakota Wint, who had spent years documenting the Aghori — the radical Shaiva renunciates of the cremation grounds — returned to Varanasi with a Mexican facilitator and offered 5-MeO-DMT, the short-acting "sapo" or toad medicine, to several sadhus. It is, by most accounts, the most overwhelming psychedelic there is: minutes long, and for most people a total whiteout of the self.

Some of the holy men had recognizably enormous experiences. One reportedly emerged in tears, having seen Vishnu sustaining the universe. An Aghori woman called out to Shiva and declared success. But Bhavani Baba, given what Wint described as an enormous dose, sat in silence for about five minutes, opened his eyes, and asked his visitors: "Are you happy now?"

He didn't dismiss the medicine. He called it a genuine glimpse of the light — useful, he allowed, for someone who needs proof the light exists. The distinction he drew instead, as the film's viewers passed it around: "Sapo is one five-minute light, but it goes. Sadhu means light forever."

Two cautions before the stamp comes down, because I promised you honesty at the summit. First: a motionless body on 5-MeO-DMT is not evidence of an unaffected mind — stillness is common at high doses, and nothing here was dosed, measured or blinded. Second: from the Aghori side, the unimpressed reaction is philosophically exact rather than superhuman. Aghora's whole project is the dissolution of dualities — pure and impure, sacred and profane, self and other. A tradition built on refusing to be captured by any experience is precisely the tradition least likely to be captured by one more extraordinary state. What can be said is that the scene rhymes almost perfectly with Kainchi — and that Wint himself walked away changed in the opposite direction from what you'd expect: his later work argues that the psychedelic was not the path.

Now take Slick's little foundation back out of your pocket. The Mind Science Foundation he started in 1958 — and called, shortly before his death, the most important thing he'd ever done — spent its first decades chasing exactly the wonders in our catalog: telepathy, biofeedback and psychokinesis, tested on monks, psychics and qigong practitioners; J. B. Rhine came to lecture; the past-life regressions ran. In the 1970s it hired three full-time parapsychologists and doubled down. And then, slowly, the ground shifted under it: through the eighties and nineties the questions migrated toward what could be brought into an MRI — meditation, minimally conscious states, the neuroscience of awareness. By 2023, the foundation born from a Yeti hunt was awarding research prizes for studies of psilocybin rewiring reward circuits and LSD synchronizing the brains of couples. Sixty-five years, one institution, and this arc:

The East, meanwhile, had been running the evaluation in the other direction all along. When LSD swept through Zen circles in the 1960s, Koun Yamada — one of the great Japanese masters of the century — was said to have tried it and reported, in effect, that whatever this was, it was not the emptiness the Heart Sutra means. Zen already had a filing cabinet for dazzling states that are not awakening: makyo, the "uncanny realm" of visions a meditator is taught to note and let pass — because a beautiful vision of Buddha does not make you one.

And that — the sadhu's distinction, the roshi's distinction, Maharaj-ji's distinction — has quietly become one of the live questions of modern psychedelic science: how much of the healing is the five-minute light, and how much is what a person builds after it goes out? Labs now put experienced meditators through psychedelic sessions and compare their brains and their phenomenology with everyone else's. State versus trait is no longer a teaching. It's a measurement problem. Which brings us to the last card of the climb — the one claim in this whole strange century that the lab has actually nailed down.
