Urvashi (Urvaśī, from Urus "thighs" + Vasi "born from", "The one born from Lord Vishnu's thighs") is an Apsara (nymph) in Hindu legend. Monier Monier-Williams proposes a different etymology in which the name means "widely pervasive," and suggests that in its first appearances in Vedic texts it is a name for the dawn goddess. She was a celestial maiden in Indra's court and was considered the most beautiful of all the Apsaras.
There are many legends about the birth of Urvashi but the following one is most prevalent.
Once the revered sages Nara-narayana was meditating in the holy shrine of Badrinath Temple situated in the Himalayas. Indra, the king of the Gods, did not want the sage to acquire divine powers through meditation and sent two apsaras to distract him. The sage struck his thigh and created a woman so beautiful that Indra’s apsaras were left matchless. This was Urvashi, named from ur, the Sanskrit word for thigh. After his meditation was complete the sage gifted Urvashi to Indra, and she occupied the pride of place in Indra’s court.
