The root of all the stories of Pururavas and Urvasi were short
proverbial expressions, of which ancient dialects are so fond.
Thus--'Urvasi loves Pururavas,' meant 'the sun rises'; 'Urvasi sees
Pururavas naked,' meant 'the dawn is gone'; 'Urvasi finds Pururavas
again,' meant 'the sun is setting.'
The same ideas pervade the mythological language of Greece.
