This book presents the progressive nature of Morita therapy across four distinct stages: an isolation rest stage, a light monotonous work stage, a labor-intensive work stage, and the social integration stage. Essentially, the experiential knowledge the clients gain by moving through the inpatient treatment becomes the therapy. Though the classical therapy was initially designed to treat anxiety-based disorders, it is presently used in Japan, China, and Australia for depression, personality disorders, eating disorders, and post-traumatic stress disorder. Morita therapy fosters akiraka ni mikiwameru-koto in the client (clear discernment), and a healthy mind/body. Throughout the book, Morita reflects on the theories of his contemporaries such as Sigmund Freud, William James, Mario Montessori, and Jean Charcot.
