In 1240, Köten famously summoned the Central Tibetan Buddhist polymath Sakya Pandita, by then already an old man, to his court at Liangzhou. Examining Tibetan and Mongolian accounts about their meeting from the last seven centuries, this study shows that it was neither compelling philosophy nor some turn of faith that converted the Mongols. It was, rather, Sakya Pandita’s violent therapeutic intervention into the space of Köten’s ill body that wrenched the Mongol body politic into the Dharmic fold.
