This volume illustrates the scroll of Rtasamhara. It is the earliest known iconography of the Vajradhatu-mandala, probably drawn by Subhakara (637-735) himself. It bears his signatures at the end: the only signature of a master of Nalanda. He was an expert sculptor of images. It illustrates every deity in sambhoga-kaya, consort, dharmakaya and nirmanakaya form. The four forms have been placed alongside for clarity. In 1982 Roger Goepper was describing the dharani-mandala in the Sumtsek of Alchi. He was puzzled by its central group whose figures were all female.
