The unrivalled corpus of medieval manuscripts unearthed in the northwestern Chinese desert town of Dunhuang in the early twentieth century divulged a trove of secrets about the practice of Chinese Buddhism. Among the thousands of liturgical texts created by local monks for the performance of rituals, almost two hundred separate manuscripts contain liturgies that were spoken aloud during healing rituals. Stephen F Teiser, Professor in Buddhist Studies and Professor of Religion at Princeton University, introduces Dunhuang and its manuscripts, surveys the practice of healing in medieval Chinese Buddhism, explores how illness can be cured through karmic means, discusses the role of confession in curing, and reflects on the process of healing in Chinese Buddhism.
