Every year around August and September, the people of Chikmagalur and other cities around India gather to celebrate the Kailash fair. They decorate the streets with coloured papers and lights, making the city a brilliant spectacle resembling a kaleidoscope. They do it in honour of Lord Shiva, who is believed to have visited the town in the form of a stone lingam. The lingam is, therefore, a sacred idol in Hinduism, and Shaivism in particular. Shiva lingas have existed and have been worshipped in some form since around 100 B.C.E. It is usually the murti, or primary idol, in temples dedicated to Lord Shiva. The idols are usually made of stone. Other versions made of clay, precious stones, wood or metal also exist and are brought out for special occasions.
