The face of Buddha is given a mask-like tranquility to express spiritual elevation. The head displays the distinctive marks of the Buddha as a Mahapurusha. The half-closed eyes add to the serene countenance. His long ear lobes are almost touching the shoulders; long ear lobes being a part of nobility. On his wide forehead is the urna or hair whorl, depicted here as an oval, signifying extraordinary insight. The ushnisha, a protuberance on top of the head, indicates superhuman wisdom. These iconographic details were derived from the traditional lakshanas on the body of the great Man, listed in early Buddhist scriptures as thirty-two major signs and eighty minor signs.
The usual rotundity of Buddha's sculptures is missing here, with the face being oval with an emphatic chin. The nose is thin and sharp, reminiscent of the Gupta period sculptures. The lips are thin and pursed, yet giving an impression of a benevolent smile. The neck ends in a round, steady base, giving the sculpture its due grace.
