Kathasaritsagara 3.3.28

But Urvaśí, remaining in the country of the Gandharvas, afflicted at her separation, was as void of sense as if she had been dead, asleep, or a mere picture. She kept herself alive with hoping for the end of the curse, but it is wonderful that she did not lose her hold on life, while she remained like the female chákraváka during the night, the appointed time of her separation from the male bird. And Purúravas propitiated Vishnu by that penance, and, owing to Vishnu's having been gratified, the Gandharvas surrendered Urvaśí to him. So that king, re-united to the nymph whom he had recovered at the termination of the curse, enjoyed heavenly pleasures, though living upon earth.
