A great book that is faithful to the story of Reiki and the simplicity of practise as passed from Hawayo Takata (who brought Reiki to the west from Japan in the 1930's) and Wanja Twan (one of the 22 people Takata made a Master). It contains the love, respect, practices, ethics and humility of Usui Shiki Ryoho - the Usui System of Natural Healing.
