There are several forms of Vairocana with four heads. The above has two hands, held in the gesture specific to this deity. He sits on a lotus base over a plinth decorated with snow lions and scrolled vegetation. The rich gilding and the extensive use of small gems indicate a Nepalese influence.
His celestial scarf forms an unusual tri-lobed arch around him. There is a half vajra finial on his head.
When Vairocana has four faces and two hands held in the meditation gesture he is known as Vajradhatu and supports a dharma wheel, as above, or an upright vajra.
