Iconography
Nāgārjuna is often depicted in composite form comprising human and naga characteristics. Often the naga aspect forms a canopy crowning and shielding his human head. The notion of the naga is found throughout Indian religious culture, and typically signifies an intelligent serpent or dragon, who is responsible for the rains, lakes and other bodies of water. In Buddhism, it is a synonym for a realized arhat, or wise person in general. The term also means "elephant".
