The right side of the brass mask represents Shiva and the left Parvati. The expression of the biune face is one of serenity born of realization. Parvati's coiffure matches up with Shiva's locks tied in a knot. The kundala in Shiva's ear is distinctively different from that of Parvati's. The mark of Shiva, the three horizontal lines decorate the male forehead and a dot the female one. The two eyes are differentiated by the depth in them: the female eye being deep and more shapely. Parvati's nostril wears an ornamental ring, while a moustache depicts the masculinity of Shiva's side.
From the philosophical point of view, this composite form represents the creative union of the active and passive principle. From the aesthetic point of view, weight, volume and grace assimilate to produce this extraordinary piece.
