On the final day of the Durga Puja festival, Durga the mother returns to her husband Shiva. This event is represented by a water immersion of the Durga sculptures.
From each pandal, community members load the idols onto a truck and then a procession follows as the truck heads towards the river. The procession involves a lot of dancing, eating, drinking, and plenty of holi powder. This was definitely one of the best cultural experiences of the entire trip :).
