The image in bronze is a colossal representation of the Bodhisattva-Vajrasattva, being 1.5 m high even in sitting position. It is the largest and possibly the best-preserved metal sculpture so far discovered in eastern India. In its anatomical proportions of the body, balanced pose of the hands and perfect geometrical composition the Vajrasattva is a remarkable creation, combining in one the previous experiences of Nalanda and Jhewari. With equal emphasis on plain surface, as of the body, and ornamentation, as of the crown and pendent earrings, the image stands between the classical and medieval ideals. It is one of the supreme expressions of Bengal's plastic art. From a contemporary bronze head of a life-size Bodhisattva-Avalokiteshvara image from the same site it seems that the Mainamati artist was a master in the cire perdue or hollow casting technique of bronze.
