This black thangka depicts the skullcup-bearing Hevajra Father-Mother in the center. He is dancing ecstatically in alidha on four maras and closely embracing his consort Nairatmya. Hevajra is surrounded with eight dancing dakinis; each one is dancing on a being. The dark setting of the painting is effective in creating a serious mood. The expression of Hevajra is ecstatic and wrathful.
Hevajra is an unexcelled yoga Tantra deity, perhaps closely related to the developments in the cult of Shiva Nataraja. Hevajra’s art is considered especially valuable in kindling the central nervous system inner fury fire that melts the inner drops from brain to groin and generates the subtle subjectivity of great bliss so essential in Tantric practices in the perfection stage. Nairatmya Hevajra’s consort is also a deity of subtle wisdom in her own right, a Tantric form of Prajnaparamita, Mother of all Buddhas. Hevajra has sixteen-arms, eight faces and four legs. The eight faces indicate the purification of the eight releases. His four legs crush four maras, who symbolize the fourfold obstacles to enlightenment the obstacle of the aggregated constituent elements of existence(skandhamara), the obstacle of egoistic entanglements (kleshmara), the obstacle of(mrityumara), and the obstacle of rebirth in the form of gods (devaputramara). According to a commentary of the Hevajra Tantra, four Hindu gods, Brahma, Yaksha, Yama, and Indra, respectively personify the four maras. The sixteen arms of Hevajra signify the purification of the sixteen voidnesses. In each of his hands he hold a skullcup. Each of the cups in his right hands contain, starting with his principal hand and moving to the lower, an elephant, horse, ass, man, camel, ox, lion and cat. Those in the left hold Earth, Water, Air, Fire, Moon, Sun, Yama, and Vaishravana. The elements in the skulls held in the left hands are usually visually represented in human form as shown in the present painting. Carrying skullcup in all of the hands is one of the most distinctive features of Hevajra. The skullcup represents the mind aspect of the body, speech, and mind notion. It also represents death and impermanence, the illusory nature of all the phenomena. The animals and gods in Hevajra’s skullcup may symbolize a universal range of all matter and beings, alive, on earth, in the heavens. Thus, the sixteen skullcups collectively symbolize the sixteen voidness orshunyata . Nairatmya, the consort of Hevajra has two hands and two legs. She is embracing Hevajra by her left hand, while the right hand holds a vajra-marked chopper. Her left leg is along with his, while her right leg is wrapped around his waist.

The upper center of the painting is rendered with the figure of great siddha Tilopa, while the bottom center is with Jambhala (Vaishravana).
