The Rigveda (8.48.3) says:
ápāma sómam amŕtā abhūma
áganma jyótir ávidāma devān
kíṃ nūnám asmān krṇavad árātiḥ
kím u dhūrtír amrta mártiyasya[23]
Stephanie W. Jamison and Joel P. Brereton translates this as:
We have drunk the soma; we have become immortal; we have gone to the light; we have found the gods.
What can hostility do to us now, and what the malice of a mortal, o immortal one?[24]
Also, consider Rigveda (8.79.2-6)[25] regarding the power of Soma: "…He covers the naked and heals all who are sick. The blind man sees; the lame man steps forth….Let those who seek find what they seek: let them receive the treasure….Let him find what was lost before; let him push forward the man of truth…." Such is indicative of an experience with an entheogen of some source…(Michael Wood (historian)).(The Story of India)
