Once upon a time, however, the King of heaven, Indra, understood that Viśvarūpa was secretly cheating the demigods by offering oblations on behalf of the demons. He became extremely afraid of being defeated by the demons, and in great anger at Viśvarūpa he cut Viśvarūpa’s three heads from his shoulders.
