"A Study of Spontaneity and Compulsion." Moshe Feldenkrais’ second book on the theory and practice of the Feldenkrais Method® includes a new 26 page foreword by Mark Reese. The Potent Self is concerned with the melding of theory and practice, the relationships between habit, emotion, motivation and posture, and the creation of a new technique for addressing human difficulties. The foundations of both Awareness Through Movement® and Functional Integration® are articulated here in more depth than in any of Dr Feldenkrais’ other writings. A must for every Feldenkrais practitioner’s library.
