Vajrapani with the vajra symbol is the spiritual son of the Dhyani Buddha Akshovya who is the progenitor of the vajra family. His spiritual mother is Mamaki. Vajrapani is also known as god of rain. It is said that when the serpent appeared before buddhato listen to his teachings, Vajrapani was charged by tathagata to guard them from the attacks of their mortal enemies, the Garudas, Vajrapani assumed a form with head, wings and claws like the Garuda themselves. Hence, Vajrapani as the protector of serpent is looked upon as the rain god. So, Northen Buddhists appeal when rain is needed or is too abundant. One can also find Vajrapani in Garuda from among the various forms of Vajrapani. Vajrapani when represented either stands or sits and carries usually  a lotus on which is placed the family symbol of Vajra. Sometime, he holds the vajra against the chest in one of his hands.
