Over the years it has inspired leading American Zen teachers, students, and practitioners. Its popularity is as high today as ever.Zen Flesh, Zen Bones is a book that offers a collection of accessible, primary Zen sources so that readers can struggle over the meaning of Zen for themselves.

    The high moral principles of Buddhism, when adopted and adapted by the Japanese warriors who became the Samurai, created an austere philosophy of singular beauty and depth. Its characteristic requirements of strict control over body and mind was exemplified by ancient warrior monks whose serene countenance, even in the face of certain death, made them much admired even by their foes. Zen may be the most misunderstood of the world's moral philosophies. While it is often classified as a Religion, it is frequently considered by its adherents to be a utilitarian philosophy, a collection of rational moral precepts or, even more simply, as a state of being. The aim of the practice of Zen is to become Enlightened and achieve the beatitude of Nirvana. To reach Nirvana means to achieve the state of extinction of pain and the annihilation of sin. Zen never looks for the realization of its beatitude in a place like heaven, nor believes in the realm of Reality transcendental of the phenomenal universe, nor gives countenance to the superstition of Immortality, nor does it hold the world is the best of all possible worlds, nor conceives life simply as blessing. It is in this life, full of shortcomings, misery, and sufferings, that Zen hopes to realize its beatitude. It is in this world, imperfect, changing, and moving, that Zen finds the Divine Light it worships. It is in this phenomenal universe of limitation and relativity that Zen aims to attain to highest Nirvana.
