 The Way of the Celestial Masters (then based at Mount Longhu, in present-day Jiangxi) was officially assigned the task of ordaining priests, but a series of revelations resulted in the creation of lineages that, in several cases, claimed to have been originated by Zhang Daoling himself. Between the mid-10th and the mid-13th centuries, five main lineages were established: Tianxin (Celestial Heart), Shenxiao (Divine Empyrean), Yutang dafa (Great Rites of the Jade Hall), Lingbao dafa (Great Rites of the Numinous Treasure), and Qingwei (Pure Tenuity). All of them were based on different codifications of ritual—including exorcist rites—but with little variation in the basic practices (Boltz 1987: 26–49; Skar 2000). Local communities, in addition, had their own ritual specialists, known as fashi (“ritual masters”), a term that designated, as it still does in the present day, lay officiants who specialize in exorcist practices (Davis 2001).
