Amavasi (New moon) day in the month of Karkatakam (July-August) is a special festival day for the temple. On this day Hindus offer 'Pithrubali' (
) in holy places, in worship of their dead ancestors. Unlike in other temples, there is no provision here for the traditional 'Vavu bali' (
). Instead, 'Namaskaram' (
) offering is made. Tens of thousands of devotees, even when from far away, throng the temple on the day, to make Namaskaram offering. 'Padachoru' (
) along with the dish 'Thalkkari' (
) is given as Prasadam for Namaskaram. 'Pada choru' (
) is prepared from the best quality 'Puncha raw rice'. More than 20 quintalls of this rice is used to prepare Padachoru on Karkataka Vavu day. 'Thalkkari'(
) is given free of cost along with 'Padachoru' (
). This dish is prepared from the stalk of Kattuchembu (Wild cococasia). Kattuchembu stalk normally produces unbearable itching. But strange as it may seen, the dish prepared from it produces no itching. Not only that, the dish is delicious, nutritive and medicinal. About 20 quintalls of the stalk have to be collected from far off places, cleaned and sliced. The reputation of the Thalkari is so high that people form neighboring districts also have started to come over here to collect it.
Amavasi of months Thulam (October-November) and Kumbam (February-March) are also observed though with lesser pomp.
Thalkkari is available on these days also.
