"Long ago there was a King called Kakutstha in the Ikṣvāku dynasty. When he was ruling over the kingdom of Ayodhyā, a war broke out between Devas and Asuras. In that war, the Devas were not able to defeat the Asuras. Seeing no other way, Indra assumed the form of a bull and Kakutstha, riding on the back of the bull fought against the Asuras and defeated them."
