It is believed that Garuda, the eagle vehicle of Vishnu, does not fly over this place. Once Garuda and Adiseshan (the snake on whom Vishnu rests in his abode Vaikunta) got into an argument as to who was more powerful and devoted to their lord. Finding Garuda a little arrogant, Vishnu went in favour of Adisesha. Worried that Garuda might be angered at this, Adisesha sought the protection of Vishnu, upon which Vishnu asked him to roll himself and hide under him. It is said that as a result of this anger, Garuda never flies over this place. There is another legend that Adiseshan won the argument and since snakes were sworn enemies of eagles, Adiseshan hid himself under the waters of the temple tank. It is henceforth believed that devotees will be relieved of "Naaga Dosham" (affliction due to serpent god) if one visits this temple. Unmarried people and childless couple can also visit this temple for salvation.
