Kashyapa and Diti in an inauspicious time during a sunset. To tease lord Brahma and other gods, Hiranyaksha ensured that earth loses its vitality and sinks into the rasatala, the lowest level in the cosmic universe. Vishnu assumed the form of a boar referred to as Varaha and restored earth to its normal position. Varaha later killed Hiranyaksha in a war that lasted for thousand years. Hiranyakashipu vowed to seek revenge and prayed to Brahma. He gained a boon which made him invulnerable to death either by day or night, either in the morning or the night, and either by a human or a beast. When the gods headed by Brahma visited Vaikuntham to tell an account of the happenings to Vishnu, a guardian named Sumukha obstructed them. They manage to meet Vishnu and also convey the misbehaviour of Sumukha. Vishnu assured that Hiranyakashipu shall be killed and Sumukha would be the serving cause.

This is covered from 5th to 29th chapters of the legend. Reconstruction by Pururava At the end of the life cycle, the temple Prahlada built was neglected and subsequently decayed. The moolavar of Varaha Narasimha was covered with crests of earth. In another life cycle, king Pururava of lunar dynasty acquired Pushpaka Vimana (divine air car) from Brahma as a boon. He saw Urvasi, an apsara at the Kailasa mountain and both fell in love. They visited Simhachalam and settled here for a while. Urvasi recollected a dream and located the idol. Pururava performed penance at Gangadhara for the same. They unearthed the idol and consecrated it after renovation. Despite his best
