This book explores how to utilize Buddhism in psychotherapy and how Buddhism itself acts as a form of psychotherapy, using Buddhism practices as a lens for universal truth and wisdom rather than as aspects of a religion. Based on the author s over 30 years of study and practice with early Buddhism and his experiences of Buddhism with his patients, the book outlines a new form of psychotherapy incorporating three Buddhist principles: the properties of the body and mind, the principle of world s movement, and living with wisdom. This technique provides a unique perspective on mental health and offers new approaches for clinicians and researchers to effectively addressing mental health and well-being.
