Legend.
The temple follows the legend of it twin temple, Devapiran temple. As per Hindu legend, the place finds mention in "Brahmanda Purana" and "Padma Purana" where it is called Kedara Nilaya. Once a sage named Suprabha wanted to perform penance and in his search for land, he ploughed at this place. He found a balance ("tola") and a bow ("vil"), which, when he lifted, turned into a couple. The couple were cursed by Kubera once for insulting them. Since the bow and balance were redeemed to their original form, the place is called Tolavillimangalam. The sage Suprabha continued to perform penance, at the end of which, the Devas received the share of offering ("Havibhaga"). Vishnu was pleased by the devotion of the sage and since he appeared with Devas, he came to be known as Devapiram.
The sage continued to perform penance at this temple and while walking down the river with lotus pond, he found Vishnu following him. At the request of the sage, Vishnu resided in this place as Aravindalochanar (the one who appeared from lotuses). As per another legend, the Ashwinidevadas wanted the share of the offerings made by men. They prayed to Brahma who redirected them to pray at this place. The twins came to the place and performed penance at this place. They had a dip in the tank, which came to be known as Asvini Tirtha. Vishnu appeared to them bearing lotus flowers in his had and granted their wishes.
