Ganesha, the elephant-headed son of Shiva and Parvati is widely worshipped as the munificent god of wisdom. Ganesh Chaturthi is a festival in his honour and is celebrated in the states of Maharashtra, Tamil Nadu, Karnataka and Andhra Pradesh. To appreciate this occasion, one must go to Mumbai where preparations begin months in advance. Images of Ganesha are installed within homes as well as in places of assembly. Elaborate arrangements are made for lighting and decoration and Ganesha is fervently worshipped for about 7-10 days. On the day of the Chaturthi, i.e. the last of the days dedicated to the elephant-headed god, thousands of processions converge on the beaches of Mumbai to immerse the holy idols in the sea. This immersion is accompanied by drum beats, devotional songs and dancing.
