Must be the definitive book on mystic phenomena of all kinds ... a masterful work of the highest scholarly standard, its scope, depth, and richness are unparalleled in any other book I know of, past or present.

Definitive in its synthesis, rich in its coverage, and of the highest scholarly standard ... A joy to read because of its clarity and verve — a very readable book.

Most impressive — a masterpiece.  A rich and dazzling array of theological and practical informa-tion drawn from a thousand years of historical documentation.

No other book available today relates mystic phenomena so clearly to each other.  None shows so effectively their role as an integral part of Christianity. A wonderful book, a book of marvels.
