According to the Ancient stories, King Kans the Lord Krishna’s maternal uncle sent a serpent named “Kaliya” to kill him. One day when Krishna was playing with his friends, his ball fell into the river. When they landed in the river to fetch it, Kalia attacked Krishna. When Lord Krishna won over Kaliya, he apologized to Lord Krishna and promised that he would never harm the villagers and would go away from there forever. The victory of Shri Krishna over the Kalia Nag is also celebrated as Nag Panchami.
There is another belief behind celebrating Nagpanchami. According to belief, no one was ready to drink the poison that came out after churning the ocean. Eventually Lord Shiva drank it. When Lord Shiva was drinking the poison, only a few drops of poison fell from his mouth and fell into the snake’s mouth. Only after this did the snake caste become poisonous. The snake god is worshiped on this day only to protect from snake bite.
Eight Nag Devas – Ashtanagas called Ananta, Vasuki, Padma, Mahapadma, Takshak, Kular, Karkat and Shankha are worshiped. There is a law on Nagpanchami to worship Vasuki Nag, Takshak Nag and Sheshnag. According to the belief, the worship of snakes on this day delights the serpent god. Those people who have Kalsarp Dosh in their horoscope, they should especially do special worship to Nagpanchami.
