Ameshab Ngakwang Kunga Sönam (1597–1659) was the twenty-seventh throneholder of the Sakya lineage of Tibetan Buddhism. Ameshab widely promoted the transmission of the Sakya tradition and mediated peace amid rising military conflict in Central Tibet. A prodigious historian, Ameshab wrote impactful histories of the Sakya school; the Lamdre, or “Path and Result,” tradition; and the Hevajra Tantra, which were read for centuries in Tibet and across the Inner Asian Buddhist world.
