A practitioner advances a theory that many physical and mental ailments arise from habitual misuse of the body and can be addressed through conscious guidance and re-education of posture, breathing, and coordination. He critiques contemporary physical-culture remedies as inadequate, outlines practical principles and exercises for teachers and clinicians, and supports his claims with clinical observations and philosophical reflection on human development. The work seeks to promote integrated, efficient bodily use to reduce strain, improve daily and artistic function, and foster broader physical and mental well-being.
