Vijaya Dasami - Immersion of the idols
On the last day of the five days of puja called Vijaya Dasami the idols are taken to river banks of the Ganga and dropped into the water. Since a couple of years special care is taken about the environmental impact. For example the use of lead-free paint for the idols is encouraged. For next year's puja there will be new idols created, painted and dressed.
