NAG

 Nags are the snake deities. They are found in various capacities. Ananta Nag or Shesh Nag and Karkotak Nag are but important nag’s. Karkotak is the king of a Serpent kingdom  where as Ananta Nag is the chief and the most important of all the nags. He forms the canopy with his seven hoods above the head of Lord Vishnu. Nag’s are found in the form of remnants of early fertility rites who were later worshipped as divine and semi-devine objects. They are frequently projected as ornaments of guarrdian tantric deities. Naga’s are believed to have power to bring or withheld rain. So, they are regarded as gods of rain as well. They are often projected as the protector of the laws of the Buddha.
