On the day of the Chaturthi, 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 drumbeats, devotional songs and dancing. Every year, the largest Ganesh idol is installed at Khairatabad in Hyderabad, which is more than 30 ft tall.The Ganapati Mahotsav or the Grand Festival of Ganesha is the principle festival in Bombay, the financial capital of India. In Bombay factories commission the largest of the 6000 or so Ganeshas collectively. Each of these idols can be upto 10 meters in height and are paraded on lorries decorated with multi-colored lights. At the other end of the scale, little Ganeshas are placed in nukkads or street corners and in homes, and pujas are performed daily. The festival was started by Shivaji , the great Maratha ruler, to promote culture and a feeling of nationalism amongst his subjects who were fighting against the Mughals.
