Dedicated to Lord Vishnu, this highly revered divya desam has two entrances - referred to as the Uttarayana Vaayil and Dakshinayana Vaayil - as in the Sarangapani Temple at Kumbakonam. The Uttarayana Vaayil is open from the Tamil month of Thai until the month of Aadi from there onwards the Dakshinayana Vaayil is used.
