It is on the fifth day of the bright half of the Shravan that Naga Panchami, or the festival of snakes, is celebrated. The setting sun is witness to mile-long processions of gaily-decorated bullock carts, cheerfully trundling to the nearby Shiva temple. The excitement and merry-go-round of a fair takes over, lasting well into the night. The snakes that the men had captured from the deep forests the week before can now return to where they came from.
Snake worship no doubt owes its origin to man’s natural fear of these reptiles. Hindu books are filled with stories and fables about snakes, and pictures and images of them meet you at every turn. Worshippers search for holes where snakes are likely to be found. When they have found a hole, they make periodic visits, placing before it milk, bananas, and other food that the snake is likely to fancy.
