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 public places. Elaborate arrangements are made for lighting and decoration and Ganesha is fervently worshiped for about 7-10 days.

Each of these idols can be up to 10 meters in height and are paraded on lorries decorated with multicolored 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. This festival was initially started by Shivaji, the great Maratha ruler, to promote culture and a feeling of nationalism amongst his subjects who were fighting against the Mughals.
After his death the festival was celebrated but on a smaller scale. In 1894 when the British banned public assemblies Lokmanya Bal Gangadhar Tilak who felt that this was the way of spreading the freedom message through a legitimate religious festival revived the festival.
On full moon day every idol is taken down to the Chowpatty beach accompanied by hordes of people singing and dancing and is immersed in the Arabian Sea.
Ganpati is the god of learning. He is addressed as the "Remover of Obstacles" ("Vignaharta"). His devotees believe that no enterprise will succeed unless he is invoked. The picture of Ganpati is often found on the doors of houses and printed on wedding cards. On the occasion of the Ganpati festival a large number of images are made of all possible sizes, and people buy them to keep in their houses as a divine guest for one and a half, five, seven, or ten days, after which the image is taken out ceremoniously and put into the river, sea or well for immersion or "visarjan". When he is immersed in the water, people sing,
"GANPATI BAPPA MORYA, AGLE BARAS TO JALDI AA,"
("father Ganpati, next year come again.")
("father Ganpati, next year come again.")
