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. Finally, Holika, Prahlada's evil aunt, tricked him into sitting on a pyre with her. 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, who survived while Holika burned. Vishnu, the god who appears as an avatar to restore Dharma in Hindu beliefs, took the form of Narasimha - half human and half lion (which is neither a human nor an animal), at dusk (when it was neither day nor night), took Hiranyakashyapu at a doorstep (which was neither indoors nor outdoors), placed him on his lap (which was neither land, water nor air), and then eviscerated and killed the king with his lion claws (which were neither a handheld weapon nor a launched weapon).
