Yamantaka

Yamantaka is the wrathful form of Manjushri, the embodiment of all of the Buddha's wisdom. He took the form of a fierce bull headed deity in order to subdue the Lord of Death. Wrathful deities wear bone and skull ornaments and often have a terrifying and demonic appearance. But their "anger" is directed against our own negative emotions and ego grasping which prevent our attainment of Buddhahood. The Wheel of Sharp Weapons calls on Yamantaka to "trample him, trample him, dance on the head of this treacherous demon of selfish concern." It is the wisdom realizing emptiness that is Yamantaka's actual weapon of destruction and it is the self-grasping ego that is destroyed.
