The First Book of Do-in Guide Practique 1 Paperback – January 1, 1971 by Jacques de Langre
 
Text in English and French. The vital energy and meridians of the body constitute a science with universal applications. For instance, in Judo we utilize the pressure points of our opponent to place him out of commission whereas in Do-in we use these same points to enhance our physical strength and mental condition. Meditation, Aikido, T'ai Chi Ch'uan, Yoga and shiatsu are close relatives of Do-in. The study of these disciplines id truly worthwhile. Because of this renewed interest in all these applications of the Yin and Yang principle, ancient Do-in, which was almost forgotten has returned to help mankind today. A book on Do-in technique would not be complete if it did not present the few diagnostic and treatment points for the illnesses of our time as well as a table showing the pathways of the meridians their polarity and a specific guide showing how to treat various ailments by treating the various pressure points. All directions contained in this book are specifically meant for self- application to one's own body.
