Many people lose sight of snakes. You too must have seen many snakes in your life, and you must have known that the snake's tongue is divided in front, but do you know why this is so? A deep secret is hidden behind the snake's tongue being cut into two parts, which is mentioned in the Mahabharata. The Mahabharata, written by Maharishi Ved Vyasa, has a very interesting story involving the tongue of snakes.
According to the Mahabharata, Maharishi Kashyapa had 13 wives. Kadru was also one of them. All snakes are children of Kadru. At the same time, another wife of Maharishi Kashyap's name was Vinata, whose son is Birchraj Garuda. Once both Maharishi Kashyap's wives Kadru and Vinata saw a white horse. On seeing him, Kadru said that the tail of this horse is black and Vinata said that it is not white. Both were bet on this matter.
Then Kadru asked his Naga sons to reduce their size and wrap it with the tail of the horse so that the tail of the horse would look black and win that bet. At that time some Naga sons refused to do so. Then Kadru cursed his sons that you will be consumed in the sacrifice of King Janmejaya. Hearing the curse, all the snake sons clung to the tail of the white horse according to their mother, causing the tail of that horse to appear black.
Losing the bet, Vinata became Kadru's maid. When Vinuta's son Garuda came to know that his mother had become a maid, he asked Kadru and his Naga sons to bring me such an item so that my mother would be freed from your slavery. Then the Naga sons said that if you bring us nectar from heaven, then your mother will be freed from the slavery of our mother.
At the behest of the Nagaputras, Garuda brought the nectar urn from heaven and placed it on the Kusha (a kind of streaked grass). He asked all the serpents to take a bath before drinking the nectar. At the behest of Garuda, all the snakes went to bathe, but in the meantime, Devraj Indra came there and went back to heaven with the nectar urn.
When all the snakes came after bathing, they saw that Kusha did not have a nectar vase. After this, the snakes started licking the grass on which the nectar was placed. He felt that a small fraction of nectar must have fallen at this place. By doing this, he did not get the nectar itself, but due to the grass, his tongue broke into two pieces.
