In compiling the following pages, I have, to a great extent, followed the plan adopted by A. Lasson in his work on "Meister Eckhart," but this book is not a translation of the latter, nor is it intended to deal exclusively with Eckhart's views. Its purpose is to be a guiding light for the comprehension of the mysteries of the Christian religion, and if, in the representation of occult truth, I draw upon Eckhart's writings more liberally than upon those of any other mystic, it is because he seems to exceed all others in the profundity of knowledge and in that clearness of expression which gained for him the title of a Master in the knowledge of Christ.
