Vajrapani is a Bodhisattva who represents the energy of the enlightened mind and his mantra also symbolizes that quality. He is pictured dancing wildly within a halo of flames, which represents transformation. He holds vajra (thunderbolt) in his right hand, which emphasizes the power to cut through the darkness of delusion. He looks wrathful, but as a representation of the enlightenment mind, he’s completely free from hatred.
