Vajravidarana is a male meditational deity with a bodhisattva appearance very similar to Vajrasattva but he holds a visvajra (double thunderbolt sceptre) in his right hand.
On paintings, he is either white and peaceful, as the four figures above,
or green and semi-wrathful – this one doesn’t look very wrathful but he is definitely green! (Note that his legs are not in the vajra position).
Here is a semi-wrathful one, with frowning eyebrows.
13th-14th century, Tibet, Vajravidarana, blue, private collection, photo by Bonhams, published on Himalayan Art Resources.
The third form is blue.
He is standing on two victims, adorned with a skull crown and a garland of severed heads, brandishing the visvajra like a weapon, wearing an animal skin as a loin cloth, snake ornaments and a vajra pendant across his chest.
He also wears a human hide and an animal skin over his back.
Undated (13th c?), same as before.
