"I like the passion and enthusiasm of an author in touch with something real who pursues it with an open mind. Implicit here is the author's seriousness and commitment. He believes his subject makes a difference and he communicates this to the reader. The author's perspective gives some startling and important insights into a tradition that is for the most part unknown and ignored." ― Christopher Bamford, Lindisfarne Press Dan Merkur is a Lecturer in the Department for the Study of Religion at the University of Toronto.
