(skt.: naga; tib.: lu) The Sanskrit word naga means snake or serpent. Nagas belong half to the animal realm and half to the god realm. Nagas are often snake-like in form, creatures with the torso and head of humans, and the body and tail of a snake, though they can assume human form at will. They dwell in a variety of locations ranging from waterways and underground locations and also in unseen realms. They are broadly divided into two classes: those that live on land (thalaja) and those that live on water (jalaja). The Jalaja-naga live in rivers as well as in the sea, while the Thalaja-naga are regarded as living beneath the surface of the earth.
