In his one-head + two-hand form Vairocana/Vairochana usually holds his hands in a gesture that is proper to him (see the page on ‘Hand Gestures’ in the left-hand column of this blog). The above has cold gold and pigments on his face, lapis lazuli powder in his hair. He is adorned with princely jewellery including armbands with a Kirtimukha design.
On rare occasions he is standing.
This is Vajradhatu, a four-head + two-hand form of this dhyani buddha who holds a wheel of dharma (cakra) in his cupped hands.
The hair of the four heads is joined together in a tall chignon topped with a flaming jewel finial.
Like all other dhyani buddhas, he may also have a buddha appearance, in which case he usually displays the ‘turning the wheel of dharma’ gesture.
