etau tau parsadav asya
sapad yatav asad-gatim
punah katipayaih sthanam
prapatsyete ha janmabhih
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
These two personal assistants of the Supreme Lord, having been cursed, have been destined to take birth in demoniac families. After a few such births, they will return to their own positions.
