There's one short, strange hymn in the Rigveda — 10.136 — that doesn't sound like the rest of it. No sacrifice, no priest, no fire-altar. Just a wild long-haired man who has drunk something, left his body, and is flying. "Long-hair holds fire, holds the drug, holds sky and earth. Long-hair reveals everything, so that everyone can see the sun. Long-hair declares the light."1
This is Keśin — the "long-haired one." And Billinge's claim about him is large: Keśin is the Vedic prototype of the yogin, the earliest snapshot in the entire tradition of a man doing what would later be called yoga.2 Before the yoga-sutras, before haṭha, before the cakra-system, there's this hairy ecstatic riding the wind with poison in his cup. If you want to know where the yogin comes from, the tradition's own answer points here.
This page is that prototype. Keśin is the wild ancestor of the WarYogin, an adherent of Rudra, and probably a Vrātya — an outsider who chose the fringe.
Keśin is the long-haired ascetic of Rigveda 10.136, described in the throes of an ecstatic experience that Billinge reads, via Kramrisch, as Rudra-Śiva entering his body.3 The description is vivid and physical: "Entranced, the mystic upholds heaven and earth; weightless, he soars with the wind; heated, he glows with the sun. His body is limitless. He has drunk the poison with Rudra-Śiva."4
Notice the three powers stacked in that one sentence — he upholds (sky and earth), he soars (weightless, with the wind), he glows (heated, like the sun). These are the same three things the developed yogin claims: cosmic support, levitation/khecarī, inner heat/tapas. Keśin has them already, in the oldest layer of the text, without any of the later machinery.
His allegiances place him precisely. He's "an adherent of Rudra." He's "perhaps a Vrātya, an outsider who has chosen to stay on the fringes of society." His ally is "Vāyu, the god of wind and horses" — he "rides the wind like a horse, which he controls with his own breath" and "travels outside of his own body."5 That last detail is the seed of everything: breath-control producing out-of-body flight. And he shares Rudra's poison: "Long-hair drinks from the cup, sharing the drug with Rudra."6
The mechanism hidden in the Keśin hymn is the one that becomes prāṇāyāma: he controls the wind-horse with his own breath, and rides it out of his body.
Billinge draws the line tight. Keśin "rides the wind like a horse, which he controls with his own breath. He is swathed in wind and travels outside of his own body."7 Read that as a technical instruction in mythic clothing: the wind is the breath (prāṇa = vāyu), the horse is the breath-current you learn to ride, and the controlling-it-with-his-own-breath is breath-regulation. The payoff — "travels outside of his own body" — is the out-of-body flight the later tradition names khecarī, moving-in-space. Keśin is doing, ecstatically and without a system, exactly what the breath-as-sacrifice tradition will later codify: using the breath to detach consciousness from the gross body.
The horse-wind-breath cluster isn't incidental. It runs across the whole Indo-European world — Billinge notes "the symbolism of the horse with wind and breath is found throughout the ancient artwork of the Indo-European diaspora."8 The Vrātya's secondary patron is Vāyu, god of wind and horses; the breath you ride is a horse because the wind you ride is a horse. So Keśin's flight isn't a one-off poetic image — it's the archaic form of a technology (breath → wind → flight) that the Vrātyas practised and the yogins inherited.
And the poison matters. He drinks the drug with Rudra — he shares Rudra's cup, which means he shares Rudra's nature: the one who can hold what would kill others. The later yogin's claim to transmute poison into nectar starts here, with a wild man who drank what Rudra drinks and flew instead of dying.
This page hands the tradition its origin-figure. It gives prāṇāyāma its Vedic prototype (breath-controlled flight before any technique). It gives the Vrātya a named exemplar — the outsider on the fringe. It connects to Rudra as Yogeśvara (Lord of Yoga) and to the Paśupati seal as the visual companion. And it seeds the khecarī/aviator material the alchemical-body cluster develops.
Billinge pairs the Keśin hymn with a piece of hard archaeology: the seated, horned figure on the stone seal from Mohenjo-Daro in the Indus Valley, conventionally called "Paśupati" (Lord of Creatures, a Rudra epithet).9 The seal shows a figure in what looks like a yogic posture, surrounded by animals. Billinge reads Rudra as "the bull of bulls that can only be approached through yoga," and lines the seal up next to Keśin as twin evidence for an archaic, pre-classical yoga.10
This pairing is doing real argumentative work, and it's worth seeing clearly. The Keśin hymn is textual evidence (oldest layer of the Rigveda); the Paśupati seal is material evidence (Indus Valley, pre-Vedic or contemporary). Put together, Billinge argues, they show a yogic state of transcendence attested at the very root of Indian civilization — the long-haired wind-rider in the text, the seated horned ascetic on the seal. The case is the perennialist thesis's strongest archaeological leg.
But it's also where the case has to be handled honestly. The "Paśupati seal" identification is contested in scholarship — whether the seated figure is proto-Śiva, whether the posture is genuinely yogic, whether there's any continuity at all between Indus iconography and Vedic religion are all live academic disputes. Billinge presents the seal-plus-Keśin pairing as settled evidence for ancient yoga; the more cautious reading is that the textual Keśin is solid (the hymn exists, it does describe an ecstatic ascetic) while the seal is suggestive but disputed. The case study is the page's clearest instance of the dating tension: a genuinely archaic ecstatic-ascetic figure (Keśin) gets recruited to support a much stronger continuity-claim (unbroken yoga from the Indus Valley) that the evidence doesn't quite carry.
You won't levitate. But Keśin's core move — ride the breath-wind to loosen consciousness from the body — is the seed of a practice you can actually run, and the WarYogin reads it as the most archaic form of his breath-work.
You sit. The room is still. You begin to lengthen the breath — slow, even, the inhale and exhale matched — until the breathing becomes the only moving thing, a steady wind passing through you. You stop doing the breath and start riding it: attention rests on the current itself, the wind-horse, and you let it carry you. The body gets quiet, heavy, then strangely far-off — the "travels outside of his own body" begins as a loosening, the sense of being slightly behind or above the physical frame. You don't grab for anything dramatic. Keśin's flight is ecstatic, not engineered; the practice is to ride the wind until it lifts, not to force the lift.
The transferable instruction is the lineage's oldest one: the breath is the horse, and you learn to ride it. Before any cakra-map, before any kumbhaka count, there's just this — a long-haired man controlling the wind with his own breath until he comes loose from his body. The WarYogin treats his breath-work as a return to that root: not a technique bolted onto the body, but the original wild capacity the technique was later built to reach.
Ecstasy without ground. Keśin is wild, weightless, flying — and the failure is taking the wildness as the whole thing, chasing the ecstatic high with no Rudra-discipline under it. The sign is the practitioner who wants the soaring without the poison-drinking — the bliss-state without the capacity to hold what would destroy a lesser nervous system. Keśin can fly because he shares Rudra's cup; the seeker who wants the flight without the fierce ground gets dissociation dressed as transcendence.
Treating the prototype as the destination. The mirror failure: romanticizing the archaic wild-man as the goal rather than the seed. Keśin is the prototype of the yogin, not the finished yogin — ecstatic, uncodified, riding the wind by gift rather than mastery. The sign is the practitioner who fetishizes the wild ecstatic and refuses the discipline (the breath-craft, the long training) that turns the gift into a reliable capacity. The hymn is a root, not a finish line.
The Keśin hymn itself is solid bedrock — Rigveda 10.136 exists, it does describe a long-haired ecstatic ascetic with the three powers (cosmic support, flight, heat), and Kramrisch's reading of it as a Rudra-possession experience is mainstream scholarship.11 The breath-wind-horse complex and the Vrātya-affiliation are well-supported reconstructions.
The reach, as in the case study, is the continuity-claim — the leap from "this hymn describes an archaic ecstatic" to "unbroken yoga from the Indus Valley Paśupati seal forward." The seal identification is genuinely contested, and the vault's critical-historical spine would insist that even if Keśin is a real archaic ascetic, the integrated subtle-body yoga Billinge wants to trace back to him is an 8–10th c CE development. The seam the vault holds: Keśin as an archaic ecstatic is defensible; Keśin as the start of an unbroken cakra-and-nāḍī lineage is the perennialist overreach. [PARAPHRASED — Billinge synthesis] applies to the continuity.
Open question: Keśin's powers (support, flight, heat) are described as given in ecstasy — he drank, Rudra entered, he flew. The later tradition makes them earned through technique. Is the archaic ecstatic-gift model and the later disciplined-attainment model two genuinely different things that got fused under one word "yoga" — and did the systematization gain reliability at the cost of the wild, given quality the Keśin hymn still has?
Billinge's Keśin runs on Kramrisch and Eliade, and the seam is the same one that runs through the whole prototype-claim. Kramrisch supplies the Śaiva-specific reading — Keśin's ecstasy is Rudra entering him, the long hair is Rudra's (the matted-hair ascetic), the poison is shared with Rudra.12 Eliade supplies the history-of-yoga reading — Keśin as an early data-point in the long evolution of yogic and shamanic ecstasy techniques across cultures.
They converge cleanly: both see Keśin as a genuine archaic ascetic and as evidence that ecstatic body-techniques predate the classical systems. The tension is in what the figure proves. For Kramrisch, Keśin proves something about Rudra — that the wild god's possession-ecstasy is ancient. For Eliade, Keśin proves something about yoga — that the technique-lineage has deep roots. Billinge fuses them into a claim about continuity (ancient Rudra-ecstasy = the root of all later yoga), and that fusion is where the perennialist pressure enters. The split reveals the page's real question: is Keśin evidence for a god (specific, Śaiva) or evidence for a method (universal, evolving)? Reading him as both, fused, is exactly the move that lets Billinge claim unbroken descent — and it's the move the critical-historical spine resists.
Plainly: this is the origin-figure of breath-driven altered states, which connects to the psychology of ecstatic/trance states and to the history of how a wild capacity gets turned into a disciplined system.
Psychology: Altered States (or the nearest consciousness-state page) — Keśin riding the breath-wind out of his body is the archaic description of a breath-induced altered state — the same territory modern psychology studies as trance, dissociation, and the consciousness-shifts of paced breathing. The structural parallel: breath-regulation reliably loosens the ordinary body-bound self, and every tradition that found this built a vocabulary for it. The insight neither domain reaches alone: the "travels outside of his own body" of the Keśin hymn and the depersonalization/out-of-body phenomena of breath-work in the lab are the same phenomenon described in different registers — which means the failure mode also transfers: ecstasy-without-ground (chasing the dissociative high with no stabilizing discipline) is a known clinical risk, and Keśin's "shares the drug with Rudra" is the tradition's intuitive insistence that the wild state needs a fierce, grounded container or it becomes mere dissociation.
History: Modern Yoga Descends from the Akhara — Keśin is the deep-time end of the same genealogical argument the modern-yoga pages make at the recent end: the question of where yoga comes from. The structural parallel: both ask whether a present practice descends from a single ancient root or was assembled later. The insight: the genealogical argument cuts both ways and the honest position holds both ends — Keśin shows there was an archaic ecstatic-ascetic root (the wild-man with breath-flight is genuinely old), while the akhara pages show the specific modern forms (the cakra-system, the postural sequences) are recent constructions. The history of yoga isn't "ancient and unbroken" or "entirely modern invention"; it's an archaic ecstatic seed (Keśin) and a recent systematic reconstruction (modern postural yoga), with the contested middle being exactly how much of the elaborate machinery is old. Keśin anchors the "something is genuinely ancient" pole; the akhara anchors the "much is genuinely recent" pole; the truth is the tension between them.
The Sharpest Implication
The oldest yogin in the tradition isn't sitting serenely in lotus — he's a wild long-haired man who drank poison and flew. That should unsettle the comfortable image of yoga's origins. The tradition's own earliest self-portrait of the yogin is ecstatic, dangerous, fringe-dwelling, riding the breath out of his body with Rudra's drug in his cup — closer to a shaman than a wellness instructor. The destabilizing implication: the serene, controlled, systematic yoga most people picture is the late form, the domesticated descendant. The root is feral. And the feral root carries a warning the domesticated form has mostly forgotten — Keśin can fly because he "shares the drug with Rudra," because he has the fierce capacity to hold what would destroy a softer nature. The wild states are real and reachable (breath alone will take you partway out of your body), but they were never meant to be reached without the Rudra-ground underneath — the fierce, death-acquainted discipline that lets a man drink the poison and soar instead of shatter. Strip the fierceness off and keep the flight, and you don't get the ancient yogin. You get dissociation with incense.
