There exists extraordinary proof that the 7 Rivers civilization and the Iranian civilization were not simply commercial neighbours, but cultural sisters born of the same spiritual substrate. This proof is not in the seals, nor in the weights and measures, nor in the caravan routes. It is in a word — or rather in two words that designate the same thing.
Soma in Vedic Sanskrit. Haoma in Avestan Iranian. The same Proto-Indo-European root. The same plant. The same ritual. The same state of consciousness sought. Two names for one and the same spiritual tradition that lived in two sister civilizations for millennia.
Etymology: two words, one root
The kinship between soma and haoma is not a linguistic coincidence. It is the trace of a common origin. Both words come from the Proto-Indo-European root *sawH- — to press, to extract a juice. In Vedic Sanskrit, this root gives su- (to press) → soma (the pressed juice). In Avestan Iranian, the same root gives hav- → haoma.
This phonetic shift — Sanskrit s → Iranian h — is systematic in Indo-Iranian kinship. The Vedic deva are the Iranian daeva. Sarayu in Sanskrit is Haroyu in Avestan (the modern Harirud). Sapta sindhu (the seven rivers) is Hapta hindu in the Avesta. And soma is haoma.
This is not abstract linguistics. It is proof that the two civilizations — Vedic and Iranian — spoke sister languages, venerated cousin gods, and used the same sacred drink to access the same states of consciousness.
The Mongolian tapestry: the archaeological proof
In The Civilization of the 7 Rivers, I document the most revealing discovery about the nature of soma and haoma. In 2009, Russian archaeologists found in Mongolia a tapestry in a tomb dating from the first century CE, woven in Palestine or Syria and embroidered in the cities of the Indus. The motif depicts priests of Zoroastrianism — the Iranian religion, daughter of Vedism — venerating a mushroom identified as an Indian variety of the genus Psilocybe cubensis, that is, a mushroom containing psilocybin.
Now Zoroastrianism used haoma — the same drink as Vedic soma. The archaeologists deduced that soma also contained psilocybin. This corresponds entirely to the descriptions in the Rig Veda hymns and in the description of the ninth mandala — where there is never any mention of leaves, seeds, fruits or flowers, but always of fibres (aṃśu).
This tapestry — embroidered in the cities of the Indus, depicting Iranian priests, venerating a psychoactive plant — is in itself a symbol of the deep connection between the two civilizations.
What the Avesta says about haoma
The Avesta — the sacred text of Zoroastrianism, written in Avestan — devotes an entire hymn to haoma: the Hom Yasht. And what the Avesta says about haoma resonates troublingly with what the Rig Veda says about soma.
Haoma is pressed between stones, filtered, offered to fire. It gives strength, wisdom, eloquence. It drives away disease and death. It connects the practitioner with the divine. The priests who prepare it must purify themselves. It cannot be used for recreational purposes.
Therapeutic virtue, ritual framework, prior purification, connection with the divine — the correspondences with the soma of the Rig Veda are so precise that they cannot be explained by a simple late cultural influence. They testify to a very ancient common source.
The divergence: deva and daeva
But the two civilizations are not identical. They diverged — on a fundamental point that says much about their respective trajectories.
In the Rig Veda, the deva — the luminous gods — are the benevolent forces that the rishis invoke. The asura are their opposite, the obscure forces. In the Avesta, the polarity is reversed: the daeva — the same root as deva — have become demons, forces of evil. And the ahura — the same root as asura — have become the forces of good, with Ahura Mazda as the supreme god.
This inversion is one of the most fascinating enigmas of Indo-Iranian comparison. It testifies to a rupture — at a moment in history whose precise date we do not know — between the two branches of the same tradition.
But before this rupture, there was unity. And this unity was readable in one same name for the same sacred plant: soma, haoma.
Two sister civilizations, a shared destiny
In The Civilization of the 7 Rivers, I note that the small civilizations of the Karakum — neighbours of the 7 Rivers civilization — used a substitute for haoma: ephedra, cannabis and opium. A substitute that produced intense ecstatic states but not the non-duality of authentic soma/haoma.
The trajectory of the two great traditions — Vedic and Iranian — illustrates what the disappearance of soma/haoma meant. When the original plant disappears, one replaces it. And with the replacement comes a profound transformation of collective consciousness: less ego dissolution, more duality, more hierarchy, more violence.
Two sister civilizations. One same plant. And when the plant disappears, two diverging trajectories — but starting from the same luminous point.
