Hindus in Nepal, India and Bangladesh celebrate the festival by worshipping snakes to honour the serpent god. During the festival, Nepalese traditionally post pictures of Nagas above the doors of their homes to ward off evil spirits, offer prayers to Nagas, and place food items such as milk and honey in their fields for Nagas. It is believed that if Nag Panchami is observed properly every year the Nags provide good health, wealth and blessing during life. - Photos by Reuters
