Vajravarahi is named for the sow's head that emerges from the right side of head or from the top of her head. The sow or pig is a common Buddhist symbol of delusion; and her having such a face symbolizes that wisdom's conquest of delusion does not merely suppress or destroy a part of the self. Wisdom tames the delusion of egotism and transmutes its energy into compassion and great bliss. The sow's face shows that nothing has been wasted.
Vajravarahi is the essence of five kinds of knowledge, and is the embodiment of sahaja pleasure. She can walk on water, a supernatural ability demonstrating her understanding of emptiness. This wrathful Buddha takes the notion of demonic divine in new direction. Where the female Dangerous and Enlightened Protectors in the exhibition demonstrate that the female can be horrifying, this fierce Vajravarahi shows that the terrifying can be feminine. She is the "supreme Dakini of all Buddhas". Moreover as the purifying inner heat of the navel chakra, Vajravarahi embodies the ultimate experiences and realization of supreme bliss and emptiness the essence of the completion-stage practices. She controls the ago and cravings of sadhakas. There are many forms of Vajrayogini according to her postures, colour and attributes, she carries in her hands. She appears both as an independent female Buddha and a consort of shamvara or Chakrasamvara.
Here she dances in ardhaparyankasana on the back of a corpse on a lotus flower. Her complexion is red and expression is angry. Her hair is upswept and three staring eyes are wrathful. Her mouth is open, showing her teeth. Her upraised right hand holds a vajra-chopper, while the left hand, a skull bowl. In the bend of the left elbow appears a khatvanga staff, symbolizing her non-dual union with Chakrasamvara. She wears elephant hide and human skin as upper garments; a tiger skin as lower garment or skirt. She is also adorned with a crown of skulls, necklace, earrings, armlets, bracelets, waist-band, anklets, a long garland of severed human heads and a long silk scarf.
