Prahlada displayed staunch devotion towards Vishnu in his childhood. As a result, he had to face many death trails. In one such instance, Hiranyakashipu's soldiers threw him from the top of a hill and placed the mountain on him. Vishnu jumped over the hill and lifted Prahlada from the sea. Prahlada asked Vishnu to assume a deity form where the avatars of Varaha, who killed Hiranyaksha and Narasimha, the one who would kill Hiranyakashipu soon, can be seen together. Vishnu assumed the form of Varaha Narasimha, for whom Prahlada built a temple after Hiranyakashipu's death. Worship was conducted and the place was named Simhachalam (lion's hill). This is covered from 5th to 29th chapters of the legend.
