This silver statue of Mahavairocana is in a sitting posture, both hands in front of the chest performing the preaching seal, with a serene face and drooping eyes. The earlobes are long and drooping, the hair curls have spiral patterns. The Buddha’s robe covers the left shoulder, with a knotted flap of the robe rising up over the left shoulder. 
The dressing clearly inherits the ancient Gupta Varanasi/ Sarnath style. "Sarnath Buddhas are probably the greatest single achievement of the Indian sculptor", largely setting the representation of the Buddha that was followed in eastern India and South-East Asia for many centuries, and the general representation of the human body in India. A number of dated examples show that the mature style did not develop until 450–475.  Folds on clothing have disappeared, and the clothing itself is extremely thin, to the point of being transparent. The halo has become large and is often elaborately decorated. The top edge of the eye-socket is very marked, forming a sharply carved edge. The Sarnath style was the origin of Buddha images in Siam, Cambodia and Java started from 6-7th Century.
The base is a double lotus pedestal, made of copper. The Buddha statue and the base are separately cast, and the bottom of the Buddha statue has a protruding U-shaped chisel, which is convenient for inserting into the base.
