First published in 1988 Ursula Fleming's highly praised reader brought the work of this great Rhineland mystic to a new and wider audience, many of whom were unfamiliar with his life and thought. This new edition brings this work to its fulfillment. Also included are original essays by Oliver Davies, Dermot Moran and Marco Pallis. It will appeal both to those who are new to his works as well as to those who found the book in its first edition so inspiring.
