Its all starts with Ganesha Chaturthi, a Hindu festival, when Ganesha’s idols are brought in and decorated pandals are made for 7/9 days.
People worship these idols for next 7/9 days until Ganesha Visarjan. Visarjan begins with various rituals. One of them includes whispering a wish in Ganesha’s ear, people believe that doing so will make it come true before the next visarjan.
The fun part is Utulu, it refers to an object that is tied to a height. People try to break it with a stick while other people around try to distract by throwing water. Seems like a combination of Janmasthami in Mumbai, and Holi in Mathura
The idols are then taken through the streets in a procession accompanied with dancing and singing.
And then the part that I don’t understand and dislike the most. These idols are then immersed in the river/sea. Well these are the same idols people have been worshiping from last few days, how can they just throw them away into filthy water.
Well I guess in the end, its all about belief.
