Purana says Asura king Hirnyakshan was troubling everyone and once he took the Bhoomandalam to Padala Lokha. Bhoodevi felt uneasy to breathe, and she worshiped Perumaal to help “Her”. Perumal took an Avathara of Varaaha and drowned, in the ocean to pierce till Padala lokham in search of Bhoodevi.
He killed Hiranyakshan and lifted the Bhoolokam with his Korai tooth from Padala Lokha and placed it in its original place. Bhoodevi felt happy and the Bhoomandalam flourished with blessings of perumal.
He returned to Paarkadal as Varaahar, where he was greeted by Devas. He turned back once, towards Bhoolokam and he was impressed and wanted to stay there. Perumaal conveyed his wish to Garuda, who took a garland and placed it on earth. Perumal stayed in that place has Varaaha Perumal and gave darshan for Garuda. The place came to be known as Vaikunda giri.

Adiseshan is bed for for Perumal to relax, so Perumaal wanted Adiseshan to join Him.

King Tondaimaan was ardent devotee of Perumaal. Once when king was worshiping Perumaal, enemy king sent a message of war against him. King Thondaiman was unable to take action immediately; he prayed to Perumaal to help him in this situation. Venkatavan wanted to help his devotee Thondaimaan. Sanku and Chakkra were sent by Lord to fight, against enemies, who left the battlefield in defeat. Thondaimaan Chakravarthyconstructed temple for Thiru Venkatavan in this place. Thondiman had darshan of Thiru Venkatavan and then onwards Lord was known as Prasanna Venkatesa perumaal.
When Hanuman was flying with Sanjeeve parvatham, he visited this place and he wanted to worship Venkatavan. His two hands were engaged, with his Gadha in a hand and Sanjeevi Parvatham in other hand. He threw them both high in the air and worshiped Venkatavan,and caught hold of them, while falling. The place was known as Malai Vaiypuri.
