The book “The Source of Power” (“The Secrets of Dr. Taverner”) can be considered as an appendix to the book “Mental Self-Defense” . In this book, the author in the form of fascinating stories describes twelve events that took place in real life and are directly related to mental protection, only in cases so serious that the intervention of the Initiate of the highest level was required. Presented as works of art, they represent a serious study of the psychology of superconsciousness. Dr. Taverner is a real person, and his mysterious hospital is a true fact. The events described here are not so unusual as they may seem to be cases that actually took place, and the author is far from trying to capture the reader with an exciting fiction, on the contrary much had to be softened in order to make it suitable for printing. In his essay on Dr. Taverner's Secrets, Gares Knight describes the actual work of the occult order and how it turns out that the Group Ritual represents the methods of analytical psychology in action. Here you will learn about the reality behind such occult concepts as “meeting the Threshold,” creating the Group Mind, contact after death, the Planetary Spirit, and more.
