The Fengdao kejie or "Rules for Worshipping the Dao" dates from the early seventh century and is a key text of medieval Daoist priesthood and monasticism, which was first formally organized in the sixth century. Compiled to serve the needs of both monastic practitioners and priests in training it describes the fundamental rules, organizational principles, and concrete establishments of Daoist institutions. Speaking in their own voices and presenting the ideal Daoist life of their time, priests and recluses come to life in this fascinating ancient document. Livia Kohn here offers the first complete annotated translation of the Fengdao kejie, along with three introductory chapters that outline the development of Daoist organizations and institutions, discuss the date and compilation of the work, and present key issues of terminology and worldview.
