Haoma, the Persian equivalent of the Hindu Soma, is the either of life. As a celestial deity he was ‘correct in faith and the adversary of death.’ The sacrament of ancient Persian religion, probably connected with the blood-offering, said to have been instituted by Yima, was the hoama rite which was condemned by Zoroaster because of its ‘filthy drunkenness.’ However, after the modification of the orgiastic character it became the central liturgical act of Zoroastrianism.
