Naag Panchami is a traditional worship of snakes or serpents observed by Hindus. The worship is offered on the fifth day after aushi (no-moon day) of the month Shravan (according to the Hindu calendar); July/August (according to Gregorian). The blessings of Naags(serpents) of patal lok (the seven realms located below the earth, according to the Hindu mythology) are sought for the welfare of the family. Serpent deity made of silver, stone or wood or the painting of snakes on the wall are given a bath with milk and then revered.
On the Naag Panchami day Naag, cobras, and snakes are worshipped with milk, sweets, flowers, lamps and even sacrifices. Various images of Naag deities made of silver, stone, wood, or paintings on the wall are first bathed with water and milk and then worshipped with the reciting of certain Sanskrit mantras. Fast is observed on the day and Brahmins are fed. The piety observed on this day is considered a definite protection against the fear of snake bite. On this occasion, doorways and walls outside the house are painted with pictures of snakes with auspicious mantras (spells) written on them. It is believed that such depictions will ward off poisonous snakes.
