A student of Yamaguchi Sensei at Hombu Dojo in Japan for many years, Gleason Sensei has succeeded in giving us the first comprehensive exposition of the spiritual beliefs of the Aikido Founder, Morihei Ueshiba. A great companion volume for Aikido and the Harmony of Nature, this volume expresses theses concepts in the terms that he Founder himself would have used. Not an easy read, this book is best digested in manageable pieces. For the serious student of Aikido this book provides a wonderful window on how the physical techniques of the art are really a form of spiritual expression and allows one to go far beyond the viewpoint afforded by the very smell amount of writing that has been translated from the Founder's own words into English.
