Karthika festival (November-December)

The Somavara -monday–vrata, fasting is ideal for Siva. On Somavara in Karthikai month for four weeks, Sankhabhisheka to Adavalleswara is performed. Another inscription of the Chola Rajaraja II^[1] issued in his 14^thregnal year (A.D.1163) is found on the western side wall of the Mahamandapa of the shrine. This record mentions a business man Kadavuzhon Devan Udaiyan^[2] belongs to Rajasinghapuram of Thirumunaipadi Nadu, under Rajaraja Valanadu made a gift of nine gold coins for burning a santhi lamp to the Presiding deity Sri Mulasthanamudaiyar of the central shrine. These gifts of nine gold coins were entrusted to Siva Brahmanas of Kaniyalar. Here Kaniyalar^[3] refers to the temple priest who conducted the rituals in the central shrine. From this we can infer that the priests of the central shrine also agreed to burn the santhi lamp which was made on the special occasion in the month of Karthigai on the auspicious Karthigai star day^[4].
