This fully-illustrated book traces the system's evolution from a spiritual self-development system to a direct hands-on practice. The journey moves from Japan to the USA, out to the world, and back to Japan. Focussing on the basic elements in their historical context, this guide contains beautifully grounded information that captures a unique sense of the system's traditional Japanese roots. The clarity and accessibility of the teachings in the book redefine and strengthen the concept of Reiki as it is practised today.
