A Course in Miracles is something of a phenomenon that has affected the lives of many thousands of people. This three-volume set of books was received through a process of inner dictation by a psychologist at Columbia University, beginning in 1965. After ten years of preparation, the Course was first published in 1976 by the Foundation for Inner Peace. Since then, more than three million of these books have been sold, without the benefit of any paid advertising, to men and women in every walk of life and every major faith.

The Course consists of a 669-page Text, which describes the theoretical foundation upon which its thought system is based; a 488-page Workbook for Students, containing 365 daily lessons that are designed to train the mind of the student along the lines set forth by the Text; and a 92-page Manual for Teachers, which answers some of the questions most likely to be asked by one studying the Course, and clarifies some of the terms used in the books.
