Prahlad drove his monstrous father to a murderous rage. He insisted on praising Lord Vishnu who was considered a sworn enemy by his father Hiranyakashipu. When he tried to punish his disobedient son, Hiranyakashipu's potent poisons turned to nectar while his lethal weapons fell harmlessly away. In this tale of bloodthirsty revenge, Prahlad's only defence is his devotion which dramatically puts an end to all evil.
