This guide to enlightened conduct for people in positions of authority is based on the teachings of several great Zen masters of China. Drawing on private records, letters, and long-lost documents of the Song dynasty (tenth to thirteenth century), the book consists of short excerpts written in a language that is accessible to readers without any background in Eastern philosophy. In part, the teachings are a guide to recognizing genuine spiritual authority in a Zen teacher—guidance that has been much needed throughout the history of Zen, owing to the prevalence of imitators and false teachers. The book may also be read as a study of the personal qualities and conduct necessary for the mastery of any position of power and authority, whether religious, social, political, or organizational.
