Soma (Sanskrit: सोम), or Haoma (Avestan), from Proto-Indo-Iranian *sauma-, was a ritual drink of importance among the early Indo-Iranians, and the later Vedic and greater Persian cultures. It is frequently mentioned in the Rigveda, which contains many hymns praising its energizing qualities. In the Avesta, Haoma has an entire Yasht dedicated to it.

It is described as prepared by pressing juice from the stalks of a certain mountain plant, which has been variously hypothesized to be water, honey, alcohol, mead, Amanita muscaria, cannabis, Peganum harmala, pomegranate, Blue lotus1, psilocybin cubensis mushrooms, or ephedra. In both Vedic and Zoroastrian tradition, the drink is identified with the plant, and also personified as a divinity, the three forming a religious or mythological unity.

Etymology

Both Soma and the Avestan Haoma are derived from Proto-Indo-Iranian *sauma-. The name of the Scythian tribe Hauma-varga is related to the word, and probably connected with the ritual. The word is derived from an Indo-Iranian root *sav- (Sanskrit sav-) "to press", i.e. *sav-ma- is the drink prepared by pressing the stalks of a plant (cf. es-presso). The root is probably Proto-Indo-European (*sewh-), and also appears in son (from *suhnu-, "pressed out" i.e. "newly born").

Vedic Soma

In the Vedas, Soma is portrayed as sacred and as a god (deva). The god, the drink and the plant probably referred to the same entity, or at least the differentiation was ambiguous. In this aspect, Soma is similar to the Greek ambrosia (cognate to amrita); it is what the gods drink, and what made them deities. Indra and Agni are portrayed as consuming Soma in copious quantities. The consumption of Soma by human beings is probably under the belief that it bestowes divine qualities on them.

In the Rigveda

The Rigveda (8.48.3, tr. Griffith) states,

a IAST: ápāma sómam amŕtā abhūmâganma jyótir ávidāma devân

c IAST: kíṃ nūnám asmân kṛṇavad árātiḥ kím u dhūrtír amṛta mártyasya

We have drunk Soma and become immortal; we have attained the light, the Gods discovered.

Now what may foeman's malice do to harm us? What, O Immortal, mortal man's deception?

The Ninth Mandala of the Rigveda is known as the Soma Mandala. It consists entirely of hymns addressed to Soma Pavamana ("purified Soma"). The drink Soma was kept and distributed by the Gandharvas. The Rigveda associates the Sushoma, Arjikiya and other regions with Soma (e.g. 8.7.29; 8.64.10-11). Sharyanavat was possibly the name of a pond or lake on the banks of which Soma could be found.
