A Course in Miracles was first published in 1976 by the Foundation for Inner Peace, and it has grown steadily in popularity over the years, particularly after being featured on The Oprah Winfrey Show in 1992. The book contains three sections: "Text", "Workbook for Students", and "Manual for Teachers", and it has faced both acclaim and criticism, being described as everything from "New Age psychobabble" to "The New Age Bible".
