In 142 CE, the divine Lord Lao descended to Mount Cranecall (Sichuan province) to establish a new covenant with humanity through a man named Zhang Ling, the first Celestial Master. Facing an impending apocalypse caused by centuries of sin, Zhang and his descendants forged a communal faith centering on a universal priesthood, strict codes of conduct, and healing through the confession of sins; this faith was based upon a new, bureaucratic relationship with incorruptible supernatural administrators. By the fourth century, Celestial Master Daoism had spread to all parts of China, and has since played a key role in China s religious and intellectual history."Celestial Masters" is the first book in any Western language devoted solely to the founding of the world religion Daoism. It traces the movement from the mid-second century CE through the sixth century, examining all surviving primary documents in both secular and canonical sources to offer a comprehensive account of the development of this poorly understood religion. It also provides a detailed analysis of ritual life within the movement, covering the roles of common believer or Daoist citizen, novice, and priest or libationer."
