The book is based on the use of the principles of the ancient Buddhist practice of Zen as applied to one's own health. The author, a well-known martial arts theorist, shares his personal experience of confronting a mental illness that once knocked him out of normal life for many years. The book provides techniques that help an unbalanced person find inner peace, enter into harmony with the world and begin to live a full life. Mastery of these techniques will undoubtedly benefit those who are faced with life’s troubles and stress, and will reduce the risk of nervous breakdowns, strokes and heart attacks. The book is also of interest to psychiatrists, psychologists, psychotherapists and students of relevant specialties who want to look at the problems they study from a slightly different perspective.
