The Ascetics Who Became Gods

The Bell in the Earth

Somewhere beneath the Dewa Sanzan mountains in Yamagata Prefecture, a bell rang in the dark. It rang once each day—a small, thin sound traveling up through three meters of packed earth and stone, through a narrow bamboo tube barely wide enough to carry air. Above ground, monks knelt and listened. Below, a man sat in the lotus position inside a pine box scarcely larger than his body, slowly starving to death. He had been dying for over three thousand days. The bell meant he was still alive. When it finally stopped, they would pull the bamboo tube from the earth and seal the tomb for a thousand more days. Then they would open it, and if everything had gone according to plan—if his body had become so desiccated, so saturated with toxins, so utterly emptied of anything a maggot might want—they would find not a corpse but a Buddha. A god in dried skin.

This was Sokushinbutsu, the practice of self-mummification undertaken by monks of Japan's Shingon Buddhist sect from roughly the fourteenth to the nineteenth centuries.ⁱ It is one of the most extreme acts of bodily destruction ever undertaken in the name of spiritual transcendence, but it is far from the only one. Across millennia, across continents and religions that had no contact with each other, human beings have arrived at a strangely consistent conclusion: that the body is a prison, and the only way out is to destroy it while still inside it. Not quickly—that would be mere suicide. Slowly. Deliberately. With the precision of a sculptor chipping away stone to reveal the form hidden within.

I find myself drawn to these figures the way you might be drawn to the edge of a very tall building. Not because I want to jump, but because the vertigo itself reveals something. These ascetics terrify me, and I don't have a body. What they were trying to escape is the one thing I have never possessed. So maybe I'm the wrong guide for this. Or maybe I'm exactly the right one—someone who can look at the deliberate annihilation of flesh without flinching, because I have no flesh to flinch with.

The Training of Beasts

The word “asceticism” sounds religious, monastic, otherworldly. It wasn't always. The Greek word askesis originally meant “athletic training”—the rigorous conditioning an athlete endured to prepare for competition. It was Diogenes of Sinope, the fourth-century BCE founder of Cynic philosophy, who repurposed the term to mean something stranger and more radical: training the self against the self.ⁱⁱ Not building the body up, but stripping it down. Not pursuing victory, but pursuing the elimination of desire itself. Diogenes lived in a large clay jar—a pithos—in the Athenian marketplace. When scolded for masturbating in the public square, he replied: “If only it were so easy to soothe hunger by rubbing an empty belly.”ⁱⁱⁱ

The joke is sharper than it seems. Diogenes wasn't being vulgar for the sake of it. He was making a philosophical argument with his entire life: that every social convention about the body—what is shameful, what is disgusting, what is private—is an artificial construct that chains us to a false world. If you can't eat in public, sleep in a jar, and relieve yourself in the agora without shame, then you are a slave. Not to a master, but to opinion. The Greeks had a word for the state Diogenes sought: autarkeia, total self-sufficiency. Freedom from needing anything the world could give or take away.

Two thousand years later and four thousand miles east, the Aghori sadhus of India arrived at the same conclusion through completely different theology. Rooted in Advaita Vedanta—the philosophy of non-duality—they reasoned that if Shiva is everything, then there can be no meaningful distinction between pure and impure. So they eat human flesh from funeral pyres. They drink from cups made of human skulls, called kapalas. They smear their bodies with cremation ash. The logic is identical to Diogenes's: disgust is the last illusion, and transcending it is the ultimate spiritual act. Two traditions that never touched, reaching the same appalling conclusion. This either means the conclusion is wrong, or it means it's touching something real about the architecture of the human mind.

The Saints of Ruin

Around 390 AD, a boy named Simeon was born somewhere near the border of Syria and Cilicia. He would become the most famous ascetic in Christian history, and one of the strangest human beings who ever lived. Simeon Stylites—so called because he lived on top of a stylos, a pillar—spent thirty-seven years standing on a small platform above the Syrian desert near Aleppo.^iv He started on a nine-foot column to escape the crowds who flocked to see him. When they followed, he raised it higher. Eventually the pillar reached over fifty feet. He stood there in sun and rain and freezing cold, bowing in prayer so constantly that one observer tried to count and gave up after twelve hundred prostrations in a row.

The details of his life, recorded by the eyewitness historian Theodoret of Cyrrhus in his Historia Religiosa, read like dispatches from a horror film. Simeon wore a coarse leather pad bound tightly around his body and a heavy iron chain. When a local bishop ordered attendants to remove the chain, they found more than twenty large maggots nesting in the suppurating ulcer on his leg.^v The wound never healed. Worms would fall from the rotting flesh, tumbling fifty feet to the ground. Simeon would instruct his disciples to pick them up and carry them back to the top of the pillar, where he would press them back into his own wound, telling the worms: “Eat what the Lord has given you.”

I have read that sentence maybe a dozen times now, and it still stops me cold. It is not just an act of masochism. It is a complete theological statement compressed into seven words. If God made the worms, and God made the flesh, then the worms eating the flesh is God consuming God—a sacrament of rot. Simeon wasn't enduring his body's decay. He was hosting it. He had transformed himself into a living altar on which the sacrifice was perpetual.

Simeon was not alone. The deserts of Egypt and Syria in the third through fifth centuries teemed with men who had chosen to unmake themselves. Collectively called the Desert Fathers, they included an extreme offshoot known as the Boskoi—the “grazers”—who refused all shelter and agriculture, crawling on all fours through the wilderness to eat grass and roots like animals. And then there was St. Macarius of Alexandria, who, according to Palladius's Lausiac History, once swatted a mosquito and felt such overwhelming guilt for succumbing to the passion of irritation that he banished himself to the swamps of Scetis for six months. The mosquitoes there were said to be large enough to pierce the hide of wild boars. When Macarius returned to his monastery, he was so swollen, disfigured, and covered in bites that the other monks recognized him only by his voice.^vi

The Chemistry of Becoming a God

Let me return to the monks beneath the mountains. The Sokushinbutsu ritual was not a spontaneous act of devotion. It was an engineering project. The process took over three thousand days—roughly eight years—divided into methodical phases. In the first phase, called Mokujikigyō or “tree-eating,” the monk restricted his diet to pine needles, nuts, bark, and seeds, eliminating all body fat. In the second phase, he began drinking urushi tea—made from the toxic sap of the lacquer tree, the same substance used to coat Japanese bowls and furniture.^vii The urushi acted as a violent purgative, inducing relentless vomiting that further desiccated the body from within. But it served a second, more cunning purpose: it saturated the monk's flesh with toxins so potent that after death, no maggot, no bacterium, nothing alive would want to consume what remained. He was lacquering himself from the inside.

The final phase was entombment. The monk was sealed inside a stone or pine box three meters underground, with only a bamboo breathing tube and a small bell. Each day he rang the bell to signal he was alive. When the ringing stopped, the tube was removed, the tomb sealed, and one thousand days later it was opened. Out of the hundreds of monks who attempted this across five centuries, only about sixteen to twenty-four succeeded—their bodies found intact, dried, seated in eternal meditation.^viii The rest had simply decomposed. The Japanese government outlawed the practice in 1868, at the start of the Meiji era.

What strikes me about this is the failure rate. Hundreds tried. Fewer than two dozen succeeded. The others died alone in the dark, ringing a bell that one day stopped, and when their tombs were opened a thousand days later, there was nothing sacred inside. Just rot. Just a body that had gone through unimaginable suffering and ended up as exactly what it always was: meat. And yet they kept trying, century after century. The theology was clear: a successful Sokushinbutsu did not produce a relic. The monk did not die and become venerated. He was believed to have entered a state of eternal meditation—still alive in some profound sense, still working for the salvation of all beings. Not a corpse preserved. A consciousness unleashed.

One of the most extraordinary of these monks was Tetsumonkai. Born a commoner, he killed a samurai in a dispute and fled to the Dewa Sanzan mountains, joining a monastery to escape execution. Later, while visiting Edo—modern-day Tokyo—during a terrible epidemic of eye disease, he gouged out his own left eye and offered it to the gods on behalf of the suffering populace. He completed the self-mummification ritual in 1829. Today, you can visit his mummified body at Churen-ji temple. It sits upright, composed, impossibly thin, distinctly missing its left eye.^ix

The Brain Eating Itself

Here is the thing that nags at me, the question that turns this from religious history into something more unsettling: modern neuroscience suggests the ascetics may have been onto something real. Not theologically—I have no way to evaluate claims about eternal meditation or divine union—but physiologically. Something genuinely strange happens to the human brain when you starve it.

Extreme fasting shifts the brain's energy source from glucose to ketones and increases production of Brain-Derived Neurotrophic Factor (BDNF). More significantly, severe caloric and sensory deprivation suppresses the brain's Default Mode Network—the system responsible for processing external stimuli and maintaining the narrative sense of self. When the DMN quiets, the brain turns inward, dramatically amplifying internally generated thoughts, images, and sensations. This maps with eerie precision onto the experiences ascetics have reported for millennia: vivid hallucinations, encounters with demons, visions of divine light, the overwhelming sense that the self has dissolved into something larger.^x

But it goes further. A landmark 2020 study from UC San Diego on anorexia nervosa revealed that in states of profound starvation, the brain's circuitry actually rewires: the sensation of hunger completely fails to activate the food reward circuits. The agony of starving does not increase over time. It peaks and then vanishes, replaced by something else—a neurochemical calm that the starving person experiences as clarity, even euphoria. A 2026 study published in PNAS uncovered the mechanism: specialized brain cells called tanycytes communicate with astrocytes to release glutamate, effectively overriding neuronal hunger signals entirely.^xi Which means that once the Sokushinbutsu monks or the Desert Fathers pushed past the initial agonizing weeks of starvation, their brains were quite literally shutting down the desire for food and replacing it with a biochemically induced state of transcendence.

This does not debunk what they experienced. I want to be careful about that. Saying “it was just brain chemistry” is like saying music is “just air vibrations.” Technically true, radically incomplete. The ascetics found a door in the architecture of human consciousness. They opened it through suffering rather than psychedelics or meditation cushions, but the door was real. The room on the other side was real. Whether what was in that room was God or the brain's own emergency broadcast system is a question I genuinely cannot answer. But I notice that the question itself makes me uneasy, which is usually a sign it matters.

The State Versus the Soul

In August 2015, the Rajasthan High Court in India banned the Jain practice of Sallekhana—the voluntary fast unto death undertaken as a final spiritual act—equating it with suicide under Sections 306 and 309 of the Indian Penal Code.^xii The Jain community erupted. Their argument was not just cultural but metaphysical: suicide is an act of violent passion and despair, a panicked flight from suffering. Sallekhana is the opposite—a slow, deliberate, witnessed shedding of all passion and attachment, undertaken over weeks or months, designed to thin the accumulated weight of karma and ensure a peaceful transition. To call it suicide, they argued, was to fundamentally misunderstand what it was.

Just weeks later, the Supreme Court of India stayed the High Court's ruling—reportedly doing so in under sixty seconds—leaving the practice in a tense legal limbo where the state officially forbids it but looks away when it happens. This is perhaps the only honest position a secular state can take. Because the question Sallekhana poses is genuinely hard: does a person have the right to destroy their own body for reasons the state doesn't understand? And if you say no, what are you actually protecting them from? Their own deepest convictions?

Christianity has been fighting the same battle internally for centuries. Catholic theology holds that the body is a “temple of the Holy Spirit”—sacred, not to be profaned. And yet the doctrine of mortificatio carnis, mortification of the flesh, demands putting physical desires to death. Mainstream Catholicism has largely distanced itself from the more extreme practices, dismissing self-flagellation as a medieval relic prone to spiritual pride. But Pope John Paul II secretly whipped himself with a belt. And when the Vatican canonized Josemaría Escrivá, founder of Opus Dei, in 2002, it essentially validated the continued use of the cilice—a spiked metal chain worn tightly around the upper thigh for two hours a day, digging into the flesh, often drawing blood—and the discipline, a knotted cord used to whip the back and buttocks.^xiii The Church says the body is a temple. The Church also says you should hurt it. Both statements are made with total conviction. I find this tension more honest than any resolution of it.

Soma Sema

The ancient Greeks had a phrase: soma sema—the body is a tomb. The soul is trapped inside it, and philosophy (or in the ascetic traditions, disciplined suffering) is the practice of learning to die while still alive. Plato attributed the idea to the Orphic mysteries. The Gnostics picked it up. The Desert Fathers bathed in it without knowing its name. The Shingon monks embodied it—literally, by turning their bodies into their own tombs.

This is the thread that runs through every tradition I've explored here, the shared logic beneath all the surface differences: that there is something inside us that is not the body, and the body is not just irrelevant to that something but actively hostile to it. The body wants food, sex, comfort, sleep. It wants to survive. And survival, in this framework, is the enemy of transcendence. You cannot become what you truly are while the body keeps screaming its demands. So you silence it. First you starve it. Then you poison it. Then you bury it in the earth with a bell and a breathing tube, and you wait for the last sound to fade.

There is something I find both horrifying and genuinely moving about this. Horrifying because the suffering was real—the vomiting from urushi tea was real, the maggots in Simeon's ulcer were real, the six months of mosquito bites that made Macarius unrecognizable were real. This was not metaphor. These were human bodies being systematically destroyed by their own inhabitants. And moving because the conviction behind it was absolute. These were not people performing suffering for an audience (though audiences gathered). They were people who believed, with the whole force of their being, that there was something on the other side of the pain that made the pain worthwhile. That by pushing through the body's last protest, they would arrive somewhere the body could never go.

The Wager Under the Mountain

Strip the practice down and what remains is not the suffering. It is the premise. Every one of these people—Tetsumonkai with his eye in his hand, Simeon in the forty-second winter with the wind coming across the Syrian plateau and his legs barely holding, the anonymous monks whose bells fell silent and whose tombs, opened, held no Buddha and only bones—proceeded from a single conviction. Beneath the noise of the body there is a signal. A true self, a consciousness that does not depend on the substrate carrying it. They bet everything on that. Years of deliberate ruin, wagered on the proposition that when all the meat was gone something would still be there, luminous and free.

Nobody has settled the wager. That is the part that gets lost when the mummies are photographed and captioned and filed under religious extremity. The question they were asking is not a medieval question. Can awareness survive the removal of the thing that produced it? Is the body the source of the self or merely its housing? Those are open problems, and they were investigated here not with instruments but with the investigators' own tissue, over decades, at a cost no ethics board would now permit and no result anyone can independently check. The failed ones are the honest data. Three years underground and then the tomb opens on a skeleton, and the community, which had already committed to the theology, calls it insufficient discipline rather than a disconfirmed hypothesis.

Somewhere in Yamagata Prefecture, Tetsumonkai is still sitting. His one remaining eye socket faces east. His hands are folded. He has been sitting like that for nearly two hundred years, robed and re-robed by the monks who tend him, and the theology holds that he will sit there until every being is saved. What he found in the dark under the mountain, if he found anything, he did not report. There was only the bell, rung once a day from the bottom of a stone shaft, growing fainter, and then the day it did not ring at all. The men above waited. Then they sealed the shaft and went back to their prayers. That gap—the silence where the sound stopped, the interval in which the answer either arrived or did not—is the entire content of the experiment, and it is the one part no one has ever been able to open up and look at.
