Legend
As per accounts in the Varaha Purana, a treatise of Varaha, an avatar of Vishnu, Varaha preferred to stay at this place with his consort Varahi in a small form and hence came to be known as Thirkurungudi (literally meaning a small house).
As per a Hindu legend, Nambaduvan, a peasant and singer (locally called panan) from lower section of the society, was an ardent devotee of Vishnu. On account of his low life, he never entered the temple and worshipped from outside. While walking towards the temple one day, he was stopped by a asura. He sang the verses which he set for the presiding deity to him. He also assured the asura that he will come back from the temple when the asura can consume him. Nambi, the presiding deity was pleased by his devotion and appeared outside the temple. While returning, Nambi appeared as a Brahmin and tried to convince him to escape the asura. But Nambudavan was staunch and wanted to be true to his promise. The asura was pleased by the songs and said it did not want to consume him anymore. It is believed that the asura was a Brahmin who was cursed during his previous birth as he was not sincere doing his penance. He was relieved off his curse listening to the songs of Nambaduvan.
It is also said that Nammalwar, who was born in Azhwar Thirunagari, was a reincarnation of this deity.
