nirvana (n.)
1836, from Sanskrit nirvana-s "extinction, disappearance" (of the individual soul into the universal), literally "to blow out, a blowing out" ("not transitively, but as a fire ceases to draw;" a literal Latinization would be de-spiration), from nis-, nir- "out" + va- "to blow" (see wind (n.1)). Figurative sense of "perfect bliss" is from 1895.
