On the occasion of Ganga Dussehra or Dasar, the Ganga river is worshipped for ten days. This is because according to popular legend, Ganga descended on earth at this time. She was initially reluctant to come down from heaven but the meditation of Bhagiratha compelled her to do so.
This is essentially a bathing festival. During this period, people take a dip in the holy river to cleanse themselves of all their sins. It is believed that the pure waters of the Ganges can wash off all your sins.
People meditate on the banks of the River Ganges. In the evening, lamps are floated and devotional songs are sung. The clay is taken home and so is the holy water. The water has power to sanctify your home.
