Hiranyakashipu's own son, Prahlada, however, disagreed. He was and remained devoted
to Vishnu. This infuriated Hiranyakashipu. He subjected Prahlada to cruel punishments, none of which affected the boy or his resolve to do what he thought was right. But his aunt helped him. Holika was wearing a cloak that made her immune to injury from fire, while Prahlada was not. As the fire roared, the cloak flew from Holika and encased Prahlada. Holika burned, Prahlada survived. Vishnu appeared and killed Hiranyakashipu. The bonfire is a reminder of the symbolic victory of good over evil. The day after Holika bonfire is celebrated as Holi.
