[Hindu] In old-Indian (Hindu) mythology, the drink of the gods which gives (and sustains) immortality. Possibly the origin of the later Greek Ambrosia.

Amrita amrita (Sanskrit) [from a not + mrita dead from the verbal root mri to die] Immortality; the water of life or immortality, the ambrosial drink or spiritual food of the gods. According to the Puranas, Ramayana, and Mahabharata, amrita is the elixir of life produced during the contest between the devas and asuras when churning the "milky sea" (the waters of life). It has been stolen many times, but as often recovered, and it "is still preserved carefully in devaloka" (Pur E 32).
In the Vedas, amrita is applied to the mystical soma juice, which makes a new man of the initiate and enables his spiritual nature to overcome and govern the lower elements of his nature. It is beyond any guna (quality), for it is unconditioned per se (cf SD 1:348). Mystically speaking, therefore, amrita is the "drinking" of the water of supernal wisdom and the spiritual bathing in its life-giving power. It means the rising above all the unawakened or prakritic elements of the constitution, and becoming at one with and thus living in the kosmic life-intelligence-substance.
