Pancha Raksha - Mahapratisara.

The Five Protectors are a group of five deities that are the personifications of five early Buddhist texts (sutra), the oldest dated to the 4th century A.D. The personifications are also of the special verbal utterances called mantras. These five deities each have specific functions and are directed towards accomplishing worldly welfare and happiness, preventing and surviving natural disasters, curing snakebite, overcoming fear and averting pestilence and epidemics.

There are many forms for each these five deities, with multiple heads and arms, and many different traditions of practice. They are popular throughout the Himalayas and Central Asia and can also be found in China and Japan.
