The Great Epic of the Bhārata dynasty 1.57.52-53

1.57.52

sāpsarā muktaśāpā ca kṣaṇena samapadyata |
puroktā yā bhagavatā tiryagyonigatā śubhe |
mānuṣau janayitvā tvaṃ śāpamokṣamavāpsyasi || 52 ||

"After the birth of the twins, the Apsara herself became freed from her curse. For she had been told before by the illustrious one (who had cursed her) that she would, while living in her piscatorial form, give birth to two children of human shape and then would be freed from the curse. Then, according to these words, having given birth to the two children, and been killed by the fishermen, she left her fish-form and assumed her own celestial shape. The Apsara then rose up on the path trodden by the Siddhas, the Rishis and the Charanas.
