2018 Facsimile of the 1929 Edition. Illustrated.  Many consider this work by Crowley to be the foremost book on ceremonial magic written in the twentieth century. It was written especially for beginners and is considered one of Crowley's better books. Illustrated with graphs and charts. The original was privately printed in 1929 after Crowley failed to find a publisher in London and has been considered a scarce work since that time.
