We've all heard of ambrosia, the beverage of the Greek gods. The ancient
Sanskrit speakers told of a beverage that made humans immortal:

Indian legend gives a full account of the way amrita, the elixer of
immortality, was brewed out of water clear of milk, the juice of herbs, liquid gold
and dissolved precious-stones;

amrita: (Sanskrit) "Immortality." Literally, "without death
(mrita)." The nectar of divine bliss which flows down from
the sahasrara chakra when one enters very deep states of
meditation. This word is apparently the source of the Greek
amrotos, the ambrosia, food or drink, of the Gods, which
has its Vedic equivalent in the legendary elixir called soma,
a central element in Vedic rites in which it is venerated as a
Divinity.
