Stories involving the nāgas are still very much a part of contemporary cultural traditions in predominantly Hindu regions of Asia (India, Nepal, and the island of Bali). In India, nāgas are considered nature spirits and the protectors of springs, wells and rivers. They bring rain, and thus fertility, but are also thought to bring disasters such as floods and drought.
Nāgas are snakes that may take human form. They tend to be very curious. According to traditions nāgas 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.
They are objects of great reverence in some parts of South India, where it is believed that they bring fertility and prosperity.
Nāgas also carry the elixir of life and immortality. Garuda once brought it to them and put a cup with elixir on kusha grass but it was taken away by Indra. The nāgas licked the kusha grass, but in doing so cut their tongues on the grass, and since then their tongues have been forked.
