Which Hindu god is the god of the sacrificial drink Soma? Soma is the Vedic deity who personifies the sacred sacrificial drink called soma.
In the Vedas, “Soma” refers simultaneously to a ritual drink, the plant from which it was prepared, and the deity associated with both. Priests pressed the plant, strained its juice, and mixed it with ingredients such as water and milk before offering it in ritual. The drink was believed to have invigorating and immortalizing powers.
The entire ninth mandala of the Rigveda is devoted to Soma hymns, especially Soma Pavamana, which celebrates the drink as it flows through the pressing and purification process. A famous myth says that a falcon stole Soma from heaven and brought it to Manu, the first sacrificer. The Vedic god Indra is a major consumer of Soma, but that does not make him the deity of the drink itself.
Later Hindu tradition identifies Soma with Chandra, the Moon god. That lunar association is historically important, but in a question about the Vedic sacrificial drink, Soma is the canonical answer. The related Iranian ritual tradition preserves the cognate name haoma.
