Shasti is celebrated on a certain day every month. KANDHAR SHASTI is a very important festival at Palani, during the 6 days in the month of Aippasi (7th Tamil month). This is based on the mythological story of Lord Muruga Killing the demons. On this day only (once in a year) the Lord comes down the Hill, and after vanquishing the demons, ascends the Hill again. This is associated with Kandhar Shasti. The four demons (Gajamugan, Tharagan, Singamugan and Surapadman) are won by the Lord. It is a grand sight to see the dramatic representation of this. On this day devotees observe total fasting as they consider that this will offset all their sins.
