Nagas are children of Kashyapa and Kadru. Among the prominent nagas of Hinduism are Manasa, Sesha, and Vasuki.The Nairs of Kerala and the ethnically related Tulu Bunts of Karnataka are clans which are believed to have originated from the serpent dynasty. Legends say that the nagas also carry the elixir of life and immortality. Garuda once brought it to them and put a cup with elixir on the ground but it was taken away by Indra. However, a few drops remained on the grass. The nagas licked up the drops, but in doing so, cut their tongues on the grass, and since then their tongues have been forked.Nagas are snakes that may take human form. They tend to be very curious. According to traditions, Nagas are only malevolent to humans when they have been mistreated. They are susceptible to mankind's disrespectful actions in relation to the environment. They are also associated with waters — rivers, lakes, seas, and wells — and are generally regarded as guardians of treasure.
