In the Purāṇas (Purana), twelve great battles between the Devas (gods) and the Asuras (a kind of demons) have been described. The sixth battle is known as Āḍi-vaka (Adi-vaka). Kakutstha, son of King Śaśāda (Sasada) of the Ikṣvāku (Iksvaku) clan, helped Indra in this battle. Virocana (Virochana), son of Prahlāda (Prahlada), died at the hand of Indra in this battle.
