Having about 20 years of study and practice in various healing systems, I recommend this book as a practical and comprehensive tool for the study of Reiki and life energy. It will be of interest to newcomers for the history and basic techniques of Reiki. It will be instructive to practitioners and teachers through the case histories and integration with chakra energetics model. The knowledge presented is in the tradition of the original method which provides energy balancing at all levels-physical,mental,emotional, spiritual. This book illustrates the on-going development of Reiki as a growing complentary modality in the healing arts. John Harvey Gray is one of the original US Masters and has dedicated his life to sharing and teaching Reiki through classes and the establishment of Reiki wellness centers.
