This excellently painted blackground thangka depicts Yamari Heruka of the Nyingma School of Tibetan Buddhism. 'Heruka', means 'blood drinker', usually referring to male wrathful deities who adopt a fierce countenance to benefit sentient beings. According to the Nyingma lineage of Manjushri Mitra, ferocious Yamari Heruka embraces his consort at the thangka's center, rendered with his prescribed iconography of three faces and six arms holding ritual weapons. He is surrounded by a detailed entourage of eight attendants, identified by inscription as Dragtung Pema Dragpo, Yamari, Sangwa'i Dagpo, Kutrul Chidag, Tugtrul Tsedag Nagpo, Sungtrul Sogdag, Yaksha Mebal, and Tamdrin.

Directly above Yamari Heruka are Vajradhara and Manjushri, flanked by lineage gurus. In the top left corner are Manjushri Mitra, Tsuglag Palge, Vasudhara and Dricho Palchen. In the top right corner are Dragtung Nagpo, Shanti Garbha, Sanggye Yeshe, and Longchenpa, along with a Tibetan figure in monastic garb not named by inscription. The lower third of the composition depicts various protector deities related to the practice of Yamari Heruka and the Nyingma 'Revealed Treasure' (terma) traditions.
