"The Shogun Scrolls" were written by Hidetomo Nakadai, a scholar and regent in the court of Minamoto Yoritomo, the first shogun of Japan and one of the world's most ruthless generals. Recently victorious over rival clans, the shogun required Nakadai to provide detailed advice on governing all aspects of the realm. The resulting treatise can today be used as a guide for personal development and motivation.
