As per the legend, sage Suthaba was doing penance at this place. He had to amphibious powers to live both in water and land. He ignored sage Durvasa, who was waiting for him. Durvasa got angry and cursed Suthaba to become a mandookam (frog in sanskrit). Suthaba pleaded to Durvasa to get relieved off the curse. Durvasa explained him that the curse was a result of a sin he had committed in his previous birth and Lord Vishnu would appear here to relieve him. Suthaba, as a frog, continued his penance under water in the Mendaka Theertham in the temple and Lord Narayana appeared to him as Sundararajan.
