Vajrakila/Vajrakilaya or Vajrakumara is a semi-wrathful meditational deity (known as heruka) who embodies the activity of all buddhas. On paintings, he is always depicted with his consort but on sculptures he may be alone and usually has wings.
He has 3 faces with 3 eyes and bared fangs, a half-vajra finial on top of his head, six hands with various attributes. On the above picture, two of the left hands hold a trident, two of the right hands hold a thunderbolt or vajra, the other right hand has the palm open in a symbolical gesture and the remaining left hand holds a ritual dagger know as kila (phurba or phurbu in Tibetan). He wears a tiger skin loin cloth, a human skin and an elephant hide over his back and is adorned with snakes. His (4) legs normally tread on two victims.
His lower body may be a kila, topped with a makara (mythical creature) and decorated with snakes.
On the above, he is holding the kila in his main hands at heart level, above the head of the makara.
On this Nepalese-style sculpture, Vajrakila holds a kila in his main hands at heart level, two vajras with his remaining right hands, a trident and a branch in the remaining left hands. His consort, Dipta Chakra, holds a skull cup and a flaying knife and wears a bone apron.
