The Legend

Traditional teaching: On this day, Lord Shiva revealed himself as an infinite column of light (Jyotirlinga) at Tiruvannamalai. Vishnu (as boar - Varaha) tried to reach the base by digging down; Brahma (as swan - Hamsa) tried to reach the top by flying up. Neither could find the ends, and both realized Shiva's supreme nature.

The infinite column of light is commemorated by the Karthigai Deepam - the lamp lit at the top of Arunachala Hill at Tiruvannamalai, and the lamps lit at every Tamil home.
