In Hindu myth, nagas are a primeval race of divine serpent-people that play an important part in religion. They are half human and half snake, and are still worshipped as the bringers of fertility, especially in southern India. Nagas are believed to live in palaces (Patala) in the underground city Bhogavati.

Sarpa (Serpent) or Nagas-In myths, legends, scripture and folklore, the category naga comprises all kinds of serpentine beings. Under this rubric are snakes, usually of the python kind (despite the fact that naga is usually taken literally to refer to a cobra,) deities of the primal ocean and of mountain springs; also spirits of earth and the realm beneath it, and finally, dragons.These beings have their own perceptions and vary in their enlightened level as do humans and other beings.
