Ganga jal, roli and aipun are sprinkled on the gods, and then rice is showered on the deities or photos of Ram, Lakshman, Sita and Hanuman Ji.
On this festival, people conduct special poojas in their homes, sing religious hymns, and perform special rituals to glorify the deity.
So Brahmadev declared that Ravana would die at the hands of a man.
