The final volume in this treatise on the seven rays contains the fundamental spiritual structure on which the next presentation of the Ageless Wisdom teaching will build. The book is in two parts; the first part enumerates and details the Fourteen Rules for Group Initiation. These are the rules for disciples and initiates, paralleling on a higher turn of the spiral, the rules for applicants contained in the book "Initiation, Human and Solar". The second part of this volume is concerned with the Rays and the Initiations, those nine major expansions of consciousness through which the initiate becomes progressively liberated from the various forms of our planetary life, ultimately proceeding upon his chosen Path of development and service within the universe. . . 

These rules are in reality great Formulas of Approach . . . approach to a specific section of the Path and not approach to the Initiator. The initiate is becoming increasingly aware of the dynamics of the Science of the Service of the Plan. This distinctive realisation can only come when his fused and blended personality and soul expression of will has disappeared in the blazing light of the Divine Purpose. Much of this teaching, while beyond the grasp of the average student today, is invaluable in expanding the mind to contemplate the larger patterns and processes in which the individual function may be viewed in perspective. In dealing with such abstruse matters, the author again demonstrates a marvelous capacity to relate the deepest and most profound aspects of the Master's teaching to the life and the consciousness of the aspirant in the world today.
