A Course in Miracles, perhaps the most important spiritual writing of the 20th century, offers a fundamental reinterpretation of the Christian message that is spiritual, rather than religious, in its perspective. Despite its Christian terminology, it is ecumenical in approach, and its underlying ontology is reminiscent of the world's most hallowed traditions. There are three constituent parts to the Course: The Text, a Workbook for Students, and the Manual for Teachers. The Text lays out the theoretical foundation for the metaphysical system of the Course. The Workbook contains a series of 365 Lessons to be practiced daily for the purpose of retraining the mind and healing our perception. Finally, the Manual contains information for and about advanced teachers of God in a question and answer format. This volume contains all three volumes of ACIM: the unabridged Text, the Workbook for Students and Manual for Teachers volumes of the Course, prepared from the original 1972 typed manuscript. Our focus in this edition has been upon reproducing as nearly as possible the content as it was originally given to Schucman and Thetford, who were the principals who first received and edited the material that became A Course in Miracles. They believed that the book was complete when they finished the 1972 manuscript.Schucman, Helen is the author of 'Course in Miracles', published 2006 under ISBN 9780976420064 and ISBN 0976420066.
