Soma

← Encyclopedia

Soma is the pressed plant-juice at the heart of the oldest Indian ritual, and at once the plant it comes from and the god who is that juice. In the hymns of the Rigveda it is all three without contradiction: a stalk gathered in the mountains, crushed between stones and strained through a fleece, mixed with milk or water, and poured out to the gods — and a deity addressed directly, praised, and asked for vigor, healing, and long life. The whole ninth book of the Rigveda is given over to Soma as it runs through the filter, the act of pressing and clarifying narrated as if the god were purifying himself.

The three are not three names for one thing seen from different angles. They are one thing addressed at the three pitches the rite requires. The priest who gathers the stalk handles a plant; the priest who works the stones handles a juice; the priest who lifts the cup addresses a god, and the god is the juice and the juice is the plant, the whole chain held in a single act of attention. This is the native grammar of the sacrifice — the yajna, the ordered sacrifice-ritual on which the Vedic world turns — and Soma stands at its center as the one offering that is also a guest, the one substance poured to the gods that is itself counted among them. Where Agni, the fire, carries the oblation up, Soma is the oblation that walks up on its own divinity.

Mandala IX: the god purifying himself

The ninth book of the Rigveda — its ninth circle, Mandala IX — is unlike the other nine. Where the rest of the collection ranges across the whole pantheon, this book is single-minded: every one of its hundred-odd hymns addresses Soma under one epithet, Pavamana, the self-purifying, the one clarifying himself as he runs. The poetry tracks a physical process and reads it as a theophany. The stalks are soaked and crushed between pressing-stones; the green juice is poured across a stretched sheep’s-fleece filter; the strained liquid falls into wooden vats and is mixed with milk and water. Mandala IX narrates each stage as the god’s own self-clarification — the juice racing through the wool is the god running, roaring, putting on his bright robe, hurrying toward the gods who wait to drink him. The filtering is at once a mechanical operation and an act of ritual-purification: what the fleece does to the juice, the hymn says, the god does to himself, leaving the dross in the wool and arriving clarified. The verses are dense with the sound of the thing — the press, the rush through the strainer, the drip into the vat — so that the book is in part a liturgy timed to the work of the hands, sung while the pressing went on.

These Pavamana hymns are also the connective tissue between the Vedas. The same verses, set to melody, form much of the Samaveda, the Veda of chant, whose melodies were sung over the pressed Soma in the great sacrifices; the ritual prescriptions for handling and offering the drink belong to the Yajurveda, the Veda of sacrificial formula. The plant that ran through one fleece runs, textually, through the whole early corpus — the spell-and-charm collection of the Atharvaveda included.

What the drink did

What the drink did is reported plainly in the texts. It exhilarated. The poets describe a quickening, a sense of swelling beyond the body and of touching the gods. One celebrated hymn outside the ninth book — the forty-eighth of the eighth — speaks in the first person from inside the experience: the singer, in the surge of the drink, declares that he has drunk Soma and become immortal, that he has reached the light and found the gods, that the draught has carried him past the reach of malice and mortality. The Sanskrit of its third verse — ápāma sómam amṛtā abhūma — became one of the most quoted lines in the corpus, read down the centuries as the moment the rite delivered on its promise. Whether the line describes a felt rush of physical vigor, a flooding sense of well-being, or a visionary transport is exactly the question the modern botanical debate turns on; the hymn itself reports the state and not its chemistry. What it claims is plain: the drink confers, for the span of the rite, the condition of the gods. Immortality and ecstasy are not its side effects but its whole point — the drink is the bridge across which a mortal, for the length of a sacrifice, crosses into the deathless company.

The drink was above all the food of Indra, who is said to have drained it before slaying the dragon Vritra and releasing the waters — so that the cosmic deed and the priestly offering mirror each other, the god’s strength and the strength in the cup being told as one thing. Indra without Soma is not Indra; the hymns make the drink the precondition of the world-making blow. The dragon held the waters coiled; Indra drank, swelled, and struck, and the rivers ran. On the sacrificial ground the priests pour Soma to Indra and the act is understood to feed the same strength that once cut the channels of the world — every pressing a small re-enactment of the first one, the cup on the altar and the mace in the myth poured from the same vat. Where Varuna guards the cosmic order from above, it is Soma-fed Indra who acts within it, and Soma that arms the hand.

The lost plant

The plant’s identity is the long-standing puzzle, and it is genuinely unsettled. The Soma of the high Vedic age seems to have been lost early. The later ritual manuals are unmistakable on this point: they already prescribe substitutes — named stand-in plants to be used when the true Soma cannot be had — which means that by the time the system was being codified the original was no longer reliably obtainable. A rite built entirely around one drink had outlived its drink. The texts preserve clues that only sharpen the problem: Soma is said to grow on the mountains, to be brought down from the heights, associated in particular with a peak called Mujavat; it is described as ruddy or tawny, swelling, with a stalk that is pressed for juice. But the clues are a ritual poet’s clues, not a botanist’s, and the plant they point to dropped out of use while the words that described it stayed in the liturgy, unanchored.

The modern proposals have ranged widely, and the contest among them is live scholarship rather than settled fact. One line of argument fastens on the ephedra shrub, valued across Central Asia for the stimulant alkaloid ephedrine: it grows in the right mountains, is jointed and effectively leafless, yields a pressed juice, and produces alertness and stamina rather than visions — qualities, on this reading, that match a drink the warriors and priests wanted for vigor and wakefulness. A second line has proposed various other mountain plants, including the β-carboline-bearing Syrian rue, Peganum harmala, argued for on pharmacological grounds. A third, the most discussed of the twentieth century, identified Soma with the fly-agaric mushroom, Amanita muscaria, on the strength of certain images read as describing an intoxicant taken without ordinary roots, leaves, or seed — a plant that is, on this reading, all cap and no stem — together with a contested reading of a urine-recycling motif against the documented Siberian shamanic use of the same mushroom. Each proposal can point to verses that fit it and verses that resist it. None has won consensus. The mushroom identification, which once drew wide attention, has not held up under philological scrutiny — the recurring vocabulary of the stalk pressed between stones, and the elaborate filtering through wool, sit badly with a fungus that could simply be eaten — and the center of gravity in Indo-Iranian studies has moved toward ephedra without arriving at agreement. Whether Soma was a stimulant, a hallucinogen, or something milder is, on the present evidence, a question the texts do not close.

Haoma: the cult before the split

The Iranian branch of the same heritage preserves a close cognate: haoma, the pressed sacred drink of Zoroastrian ritual, named with the same word and pressed in much the same way. The correspondence is exact at the deepest level. Avestan haoma and Vedic soma are the same word in the two daughter languages; the Avestan yasna, the central act of worship in which the drink is prepared, is the same word as Sanskrit yajña, the sacrifice; the Iranian rite presses a plant between stones, strains it, and offers it to the divinity who is the drink, exactly as the Indian rite does. The Avestan hymn to the drink, embedded in the liturgy as the section recited before the priests consume the pressed parahaoma, praises haoma as healer and giver of strength in language that reads as a sibling of the Pavamana hymns. Two priesthoods, separated for three thousand years and worshipping along divergent theologies, were still, at the center of their highest rite, crushing the same-named plant between stones and drinking the god.

This is the strongest single piece of evidence that the cult reaches back before the Indian and Iranian traditions parted — that somewhere in the second millennium before the common era, before the speakers of Indo-Iranian divided into those who would compose the Veda and those who would follow Zarathustra, there was already a rite at the center of their religion in which a mountain plant was pressed, strained, and drunk as a god. The shared word, the shared pressing, and the shared divinity of the drink are not a later borrowing across the border; they are an inheritance from the common stock, carried south into India and west onto the Iranian plateau by peoples who had already been pressing it before they were two peoples. The botanical identity is lost on both sides of the line, and the same modern debate over what was pressed runs through the Iranian material — the Avesta and its commentators preserving the rite without preserving the plant — so that the puzzle of Soma is also the puzzle of haoma, and both are the puzzle of a sacrament older than either tradition that kept it.

Scholarship and texts

The drink sits at the intersection of two whole fields — Vedic philology and Iranian studies — and the question of what it was has generated a literature out of all proportion to its few dozen attested verses. The standard complete scholarly English Rigveda is Stephanie Jamison and Joel Brereton’s three-volume The Rigveda (Oxford University Press, 2014), the first full scholarly translation into English in over a century, with an online commentary apparatus that carries the technical notes the printed volumes could not hold; their rendering of Mandala IX is the current point of reference for the Pavamana hymns. Wendy Doniger’s anthology The Rig Veda (Penguin, 1981), a selection of a hundred and eight hymns including the great Soma material, remains the most widely read English gateway to the corpus, and her earlier survey of the botanical proposals appended to the twentieth-century mushroom argument cataloged the identifications then in play. The famous immortality verse is hosted in translation as Rigveda 8.48.3.

The botanical-identity literature has its own landmarks. The fly-agaric argument was made at length by R. Gordon Wasson in Soma: Divine Mushroom of Immortality (1968); it was answered, decisively for most readers, by John Brough’s “Soma and Amanita muscaria” in the Bulletin of the School of Oriental and African Studies 34 (1971), which dismantled the case on linguistic grounds. The Syrian-rue proposal was developed by David Flattery and Martin Schwartz in Haoma and Harmaline (University of California Press, 1989). The ephedra reading that now leads the field was argued by Harry Falk in “Soma I and II”, BSOAS 52 (1989), on the ground that the texts describe enhanced alertness and vigor rather than vision. On the Iranian side, the Encyclopaedia Iranica entries on haoma and on the Hōm Yašt are the standard reference points for the Avestan rite and its relation to the Vedic one. The comparison most often drawn from outside the Indo-Iranian world is with Eleusis and its sealed initiatory draught, the kykeon — a comparison of structure, a ritual drink at the heart of a cult promising a changed relation to death, and not an identification: the same twentieth-century circle that proposed a mushroom Soma proposed an ergot kykeon, and neither claim carried its field.

Into the sky

Within India the figure drifted upward over time, and the drink’s place in the later religion of Hinduism shifted from the cup to the heavens. Soma the drink and god came to be identified with the moon — the waxing and waning vessel from which the gods were thought to drink, refilling as it rose and draining as it set — so that a word that began as the name of an earthly plant ended as the name of a body in the sky. The plant pressed on the mountain, the juice strained through the fleece, the god who ran roaring through the filter: all of it gathered, in the end, into the cold cup overhead that the gods drink down through the dark half of the month and the priests can only watch refill. What the rite once tasted of, the texts no longer say.
