In Hindu mythology, a particular celestial nymph (apsara) who is most famous
for her association with King Pururavas.
Urvashi comes to stay with Pururavas
under several conditions, including that
she should never see him naked. When
she has been gone from heaven for a
while, the god Indra notices her absence
and schemes to get her back. One night
he sends several minor deities to steal
two lambs of which Urvashi is very fond,
and when Pururavas leaps up to regain
them, a flash of lightning reveals him
naked, and Urvashi leaves him. They are
separate for some time but are eventually
reunited—in some accounts for good,
and in others for only one night a year.
