Because of his disrespectful behavior toward his spiritual master. Indra lost all his opulence and was conquered by the demons, who defeated the demigods in a great fight and occupied Indra’s throne. King Indra, along with the other demigods, later took shelter of Lord Brahmā. Understanding the situation, Lord Brahmā chastised the demigods for their offense to their spiritual master. Following Lord Brahmā’s orders, the demigods accepted Viśvarūpa, who was a brāhmaṇa and the son of Tvaṣṭā, as their priest. Then they performed yajñas under the priesthood of Viśvarūpa and were able to conquer the demons.
