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. It includes 101 Zen Stories, a collection of tales that recount actual experiences of Chinese and Japanese Zen teachers over a period of more than five centuries; The Gateless Gate, the famous thirteenth-century collection of Zen koans; Ten Bulls, a twelfth century commentary on the stages of awareness leading to enlightenment; and Centering, a 4,000 year-old teaching from India that some consider to be the roots of Zen.
