A Course in Miracles is a set of self-study materials published by the Foundation for Inner Peace. The book's content is metaphysical, and explains forgiveness as placed on daily life. Curiously, nowhere does the book have an author (and it is so listed with no author's name by the U.S. Library of Congress). However, the writing was written by Helen Schucman (deceased) and William Thetford; Schucman has related that the book's material is founded on communications to her from an "inner voice" she claimed was Jesus. The initial version of the book was published in 1976, with a revised edition published in 1996. Area of the content is a teaching manual, and a student workbook. Since the very first edition, the book has sold several million copies, with translations into nearly two-dozen languages.

The book's origins can be traced back to the early 1970s; Helen Schucman first experiences with the "inner voice" led to her then supervisor, William Thetford, to make contact with Hugh Cayce at the Association for Research and Enlightenment. Subsequently, an introduction to Kenneth Wapnick (later the book's editor) occurred. acim audio During the time of the introduction, Wapnick was clinical psychologist. After meeting, Schucman and Wapnik spent over a year editing and revising the material. Another introduction, this time around of Schucman, Wapnik, and Thetford to Robert Skutch and Judith Skutch Whitson, of the Foundation for Inner Peace. The very first printings of the book for distribution were in 1975. Ever since then, copyright litigation by the Foundation for Inner Peace, and Penguin Books, has established that the information of the very first edition is in the public domain.

A Course in Miracles is a teaching device; the course has 3 books, a 622-page text, a 478-page student workbook, and an 88-page teachers manual. The materials can be studied in the order chosen by readers. The information of A Course in Miracles addresses the theoretical and the practical, although application of the book's material is emphasized. The writing is mostly theoretical, and is a cause for the workbook's lessons, which are practical applications. The workbook has 365 lessons, one for every single day of the entire year, though they don't need to be done at a pace of just one lesson per day. Perhaps most just like the workbooks which are familiar to the common reader from previous experience, you are asked to use the material as directed. However, in a departure from the "normal", the reader isn't required to believe what's in the workbook, or even accept it. Neither the workbook nor the Course in Miracles is meant to complete the reader's learning; simply, the materials are a start.

A Course in Miracles distinguishes between knowledge and perception; the fact is unalterable and eternal, while perception is the world of time, change, and interpretation. The world of perception reinforces the dominant ideas inside our minds, and keeps us separate from the facts, and separate from God. Perception is bound by the body's limitations in the physical world, thus limiting awareness. A lot of the experience of the world reinforces the ego, and the individual's separation from God. But, by accepting the vision of Christ, and the voice of the Holy Spirit, one learns forgiveness, both for oneself and others.

Thus, A Course in Miracles helps the reader find a method to God through undoing guilt, by both forgiving oneself and others. So, healing occurs, and happiness and peace are found.
