Her expression in this painting is extremely terrifying. The complexion of her body is black with a thick brown outlining. She stands in the attitude of dancing in ardhaparyanka on the back of a corpse, representing ignorance. Her upraised right hand is holding a vajra-marked chopper, and the left, held near the breast, a skull bowl filled with demon's blood. Her golden hair is upswept. Her three eyes are angry and staring. Her mouth is open, showing her teeth. She is wearing a crown of skulls with jewels. There is a head of sow on the top of her crown. Moreover she wears flowing scarves, human and elephant skins; jewel and bone ornaments and a garland of freshly severed human heads. Her hips are covered with a tiger skin. There is an arch shaped golden color aureole behind her body with wisdom fire fence.
The upper corners are filled with stylized clouds. The middle ground depicts high peaks, lakes, natural vegetation and mountainous landscape framed by clouds. The foreground is filled with rocks, lakes, natural vegetation and offerings. The lining and composition of the painting is excellent and represents the beauty of black. Moreover, the stark and dark background creates a serious mood. Thus, it is very much suitable for meditation and worship of Vajravarahi.
