Yama Dharmaraja (Tibetan: shin je cho gyal, English: Yama - King of Dharma).
Dharmaraja, dark blue in colour, has one face and two hands. With the head of a buffalo and two sharp horns he glares fiercely with two bulbous eyes and a gaping mouth. His body is thick and fleshy with long nails and an engorged phallus. In the right hand he holds aloft a spine stick tipped with a gold vajra. In the left hand outstretched he holds a lasso. Embraced on the left side by the consort Chamundi, red in colour, to the Lord she offers up a skullcup with the left hand. Standing with the right leg bent and left extended mounted atop a buffalo, red corpse and multi-coloured lotus seat he is completely surrounded by the flames of pristine awareness.
Yama Dharmaraja is a wisdom deity protector of the father class of Anuttarayoga Tantra specific to the practices of the Vajrabhairava (Yamantaka) tantras. Bhairava is common to all the Sarma Schools. The Gelugpa tradition holds Yama Dharmaraja (also known as Kalarupa, 'Black Form') in a special regard as one of their three main Dharma protectors which also include Sadbhuja Mahakala and the worldly direction guardian Vaisravana. These were the three special protectors of Lord Tsongkhapa the founder of the Gelugpa School. Although similar in appearance and name Yama Dharmaraja is not the same individual as Yama the 'Lord of Death' depicted as the central figure in Buddhist depictions of the hell realms.
