It is important for you to know that this is the only complete original edition of A Course in Miracles that the Scribe, Dr. Helen Schucman, authorized to be published by the Foundation for Inner Peace in 1975. Other books with titles such as "The Original Edition" or the "Unedited Edition" contain unsanctioned material from a first or second draft of the Course which Dr. Schucman deleted since it was not meant to be part of the published Course.
Only this edition from the Foundation for Inner Peace includes the following copyrighted material: the " Preface", "the Clarification of Terms", and "the Supplements", which Dr. Schucman also scribed. The Supplements are extensions of the Course principles and are titled "Song of Prayer" and "Psychotherapy: Purpose, Process and Practice."
The Course, as it is published in this edition and used by three million students worldwide, is a complete self-study spiritual thought system that teaches forgiveness as the road to inner peace and the remembrance of God.
