In each chapter, Dr. Berkowsky provides sufficient contextual explanatory information to allow even those who have had no prior experience with some of the elements he uses in his synthesis (e.g., Chinese medicine or Kabbalah) to be able to understand and practically apply the information presented in the chapter.
