24.31

pañcapañcāśadabdāni latā sūkṣmā bhaviṣyasi
purūravāḥ piśācatvaṃ tatraivānubhaviṣyati //

Then Urvaśî who was playing the part of Lakṣmî and was dancing and singing melodiously in unison with the music, saw Purûrava and being fired with passion forgot the part which Bharata had taught her. Bharata in a rage cursed Urvaśî saying that she would become a subtle creeper on the earth for 55 years on account of the separation from Purûrava and the latter would lapse into a Piśâcha.—29-31.
