For centuries the I Ching has been used as a basic map of conscious development, containing the underlying principles of all religions, and highly prized by followers of Buddhism.

Chih-hsu Ou-i uses the concepts of Tianti Buddhism to elucidate the I Ching—concentration and insight, calmness and wisdom, and various levels of realization.

Skillfully translated by Thomas Cleary, this work presents the complete text of the I Ching plus the only Buddhist interpretation of the oracle.
