Vajrabhairava is also an emanation of Yamantaka, who is also believed to have emerged from Manjushri. Yamantaka is the destroyer of Yama, the god of death. While Yama rides a buffalo, Yamantaka does not. Vajrabhairava however, incorporates the animal into himself, so much so that he is always portrayed with a buffalo head as his principal head. In Tibetan iconography, Vajrabhairava’s head is modeled more on the yak rather than buffalo.
Vajrabhairava has nine heads; eight are wrathful, but the ninth at the apex is that of peaceful Manjushri, his spiritual father. He has a large array of arms and also multiple legs trampling upon a host of mortal and divine creatures.
With his several heads, hands, Vajrabhairava is perhaps the most ‘cosmic’ of all Buddhist deities.
