Amazon.com Book Description (ISBN 156184019X, Hardcover)

To synthesize the aim of religion and the method of science--this was the mission of the original 'Equinox,' a massive work in ten large volumes and several subsequent books. The complete 'Equinox' is rarely available and generally beyond the economic reach of most students. This one-volume collection contains all the important magical writings from the original. It has been edited and arranged by Crowley's secretary, Israel Regardie, so the student can "find his way through the maze more easily." It includes material on Crowley's magical order, magical rituals, yoga, invocations, and sex magick among many other topics.
