Puraṣjaya agreed to kill all the demons, on the condition that Indra would be his carrier. Because of pride, Indra could not accept this proposal, but later, by the order of the Supreme Lord, Viṣṇu, Indra did accept it and became a great bull carrier for Puraṣjaya.

Gauḍīya
Translation
Indra became a great bull, and consented to be the carrier of Puraṣjaya by the order of the Supreme Lord Viṣṇu, soul of the universe.
“If Indra becomes my carrier, then I will kill the demons.” Indra, out of shame, refused to be his carrier, but by the order of Viṣṇu, he became a huge bull and carried Puraṣjaya.
