Each chapter is supplemented and expanded by a companion chapter on the same subject by Gareth Knight. In Dion Fortune's day the conventions of occult secrecy prevented her from being too explicit on the practical details of magic, except in works of fiction. These veils of secrecy having now been rolled back, Gareth Knight has taken the opportunity to fill in much practical information that Dion Fortune might well have included had she been writing today. In short, in this unique collaboration of two magical practitioners and teachers we are presented with a valuable and up-to-date text on the practice of ritual or ceremonial magic "as it is". That is to say, as a practical, spiritual and psychic discipline, far removed from the lurid superstition and speculation that are the hallmark of its treatment in sensational journalism and channels of popular entertainment.
