The book “The Source of Power” (“The Secrets of Doctor Taverner”) can be considered as an appendix to the book “Psychic 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 psychic defense , only in cases so serious that the intervention of a higher-level Initiate was required. Presented as works of fiction, they represent a serious study of the psychology of the superconscious. Dr. Taverner is a real person, and his mysterious hospital is a genuine fact. The events described here are not as unusual as they may seem; These are cases that actually took place, and the author is far from trying to captivate the reader with exciting fiction; on the contrary, a lot had to be softened.
