Mahakala from Tibet wearing an elephant skin and sitting on a bird's head trampling a fisherman, holding a Vajra in his right hand and making a sign with his left hand. Mahākāla is a deity common to Hinduism and Tantric Buddhism. In Buddhism, Mahākāla is regarded as the sacred Dharmapāla ("Protector of the Dharma"), while in Hinduism, Mahākāla is a fierce manifestation of the Hindu god Shiva and the consort of the goddess Kali. Mahakala is also a name of one of Shiva's principal attendants (Sanskrit: gaṇa), along with Nandi, Shiva's mount and so is often represented outside the main doorway of early Hindu temples.
