As per Hindu legend, Vamana, a dwarf and an avatar of Vishnu, appeared here to quell the pride of Asura king Bali. The temple is believed to be the place where the first three Azhwars, the Vaishnava saints, namely, Poigai Alvar, Bhoothathalvar and Peyalvar attained salvation. The temple is one of the Panchakanna (Krishnaranya) Kshetrams, the five holy temples associated with Krishna, an avatar of Vishnu.
