A Class in Wonders is a set of self-study components published by the Base for Internal Peace. The book's material is metaphysical, and explains forgiveness as placed on day-to-day life. Curiously, nowhere does the book have an writer (and it's so stated lacking any author's name by the U.S. Library of Congress). However, the text was compiled by Helen Schucman (deceased) and William Thetford; Schucman has related that the book's a course in miracles  is based on communications to her from an "internal voice" she claimed was Jesus. The initial edition of the guide was printed in 1976, with a modified release printed in 1996. Part of the content is a teaching manual, and students workbook. Because the initial release, the book has offered many million copies, with translations into almost two-dozen languages.

The book's roots may be tracked back to the first 1970s; Helen Schucman first activities with the "inner voice" led to her then supervisor, William Thetford, to get hold of Hugh Cayce at the Association for Study and Enlightenment. In turn, an release to Kenneth Wapnick (later the book's editor) occurred. At the time of the release, Wapnick was scientific psychologist. After conference, Schucman and Wapnik spent around per year modifying and revising the material.

Another release, this time around of Schucman, Wapnik, and Thetford to Robert Skutch and Judith Skutch Whitson, of the Foundation for Internal Peace. The very first printings of the book for circulation were in 1975. Since then, trademark litigation by the Basis for Inner Peace, and Penguin Publications, has recognized that the information of the initial model is in the public domain.

A Class in Miracles is a teaching product; the program has 3 books, a 622-page text, a 478-page scholar book, and an 88-page teachers manual. The resources could be studied in the order opted for by readers. The content of A Program in Wonders handles both the theoretical and the realistic, although program of the book's material is emphasized. The writing is mostly theoretical, and is a cause for the workbook's classes, which are useful applications.

The book has 365 lessons, one for every day of the season, though they don't need to be done at a speed of one session per day. Perhaps many such as the workbooks which are familiar to the typical reader from previous experience, you're asked to use the product as directed. Nevertheless, in a departure from the "normal", the reader isn't needed to think what's in the book, or even take it. Neither the workbook or the Program in Miracles is intended to complete the reader's understanding; merely, the components are a start.

A Program in Miracles distinguishes between information and perception; truth is unalterable and eternal, while belief is the world of time, modify, and interpretation. The planet of perception reinforces the principal a few ideas in our thoughts, and maintains people split up from the reality, and separate from God. Belief is bound by the body's constraints in the physical world, hence limiting awareness. Much of the ability of the planet supports the vanity, and the individual's divorce from God. But, by accepting the vision of Christ, and the style of the Holy Spirit, one learns forgiveness, both for oneself and others.
