This book is an enlargement on the "15 Rules of White Magic" as given by the author in "A Treatise on Cosmic Fire". The "15 Rules" apply to bringing down to the physical, the Divine Idea which is its underlying cause. Specifically, the rules examine the various phases this Idea goes through in order to be "clothed in matter", at which time it becomes manifest on the physical plane. The "magician" is the soul or Higher Self, thereby making the new physical object of divine origin. Obviously, not everyone can perform White Magic of this kind as it requires that continuity of consciousness possessed by an initiate of a certain grade. Furthermore, it is clear that if this information were easy to know, inherent dangers might befall the "magician". So, much of this book also centres on how to "become a Disciple and Initiate", and the reader has to "read between the lines" to truly learn. Hence, it is a book one returns to time and again over many years.
