From the Editor: The Zen way to self-knowledge is through an understanding of one's own true inner self, achieved through meditation and the study of koans -- startling paradoxes which cannot be solved through rational thought. This book clearly describes the essence of Zen and how it developed; its meditation and unique teaching methods; the koans and stories of the Zen masters that express its non-intellectual approach; and how Zen fits into daily life and the martial arts. Learn how to achieve calmness, clarity, and concentration through Zen. Black-and-white illustrations.
