The temple is at Thakazhi, a village six km away from Ambalapuzha in Alleppy district. Lord Shastha is the main deity. The deity faces the east. There are no sub deities.  Legend says that Vilwamangalam Swamiyar found an idol that came along with the waters of the river Pampa. He entrusted the idol with Sage Udayarkka. He consecrated the idol here. There is also a version that the idol was the one that Parasuama had consecrated at Otharamala which had been immersed in the mud of the filed during the very heavy rains. As the idol had been covered with mud, the Sage cleaned it more by rubbing the mud away and washing it. Hence the place where it was found came to be known as Thazhuki (rubbed gently) and then it became Thakazhi. There is also the belief that it was once a Buddhist temple.  It was the ruler of Chembakaserry and the local people who built the temple. The “Valiyenna “that is prepared and given from this temple has great medicinal quality. It is supposed to cure arthritis, jaundice, and Tuberculosis. It is made from 84 medicinal plants from the Othara hill, 64 other medicinal plants and many oils. There is a belief that the Kerala Brahmins learned medicine from the Buddhists. So, the preparation of the oil must have come to them from the Buddhists who had the temple there. The temple is now under the Travancore
