The literature on Theurgy is extensive, but much of it is theoretical and fairly inaccessible. Mouni Sadhu's Theurgy is different in that it is both thoughtful and lucid, and like his other works, including Samadhi and Meditation, remains unexcelled in the literature of practical philosophy for Western readers.
The book is permeated with the burning faith and spiritual experience of the author and cannot fail to inspire the sensitive reader. Here the student is told in simple language the why, when and how to act. This differs from any other work on a similar theme and, to date, nothing like it has yet appeared.
