Amrta

(“imperishable”) In Hindu mythology
this is the nectar of immortality, which is
churned from the Ocean of Milk through
the combined efforts of the gods and the
demons. The word is also used
metaphorically to describe anything
believed to be especially purifying and
powerful, such as charanamrta (“foot
nectar”). Charanamrta are the liquids
(milk, water, etc.) given to devotees
(bhakta) to drink, which are often the
fluids in which their guru’s feet or the
image of a deity have been bathed. See
also Tortoise avatar.
