Cheltenham, UK: Skylight Press, 2010. Paperback, 242 pages. New.
Originally published in 1975, this is a classic textbook of the Western Mystery Tradition. It covers a wide range of topics within a Christian-oriented Qabalistic framework:
methods of inner plane communication
contact with the Masters
the ‘consciousness’ approach of Carl Jung
the vision of Dante
the archetypal power of the Hebrew alphabet
the Qabalistic Tree of Life
The book also contains powerful visualisation exercises and examples of communication with angelic and elemental contacts. While this book can be used as a course of self-instruction, it is also an important modern reference book of magical theory and practice, and has been used for decades.
