There are two stepped entrances to the sanctum, Utharayana Vaasal and Dhakshanayana Vaasal, each open for a six-month period. From 15 January to 15 June, Utharayanya Vaasal is opened, Dhakshanaya Vaasal is for the other six-month period. Pundarikakshan, the presiding deity of the temple is named "Maayavan" during
