Yet another essential principle of A Course in Miracles may be the proven fact that the physical world can be an illusion. It posits which our physical activities are unreliable indications of reality and that correct notion can only just be performed via a shift in consciousness. The Program distinguishes involving the "real life," which is a state of peace and oneness beyond the substance realm, and the "vanity earth," known by anxiety, separation, and conflict. In accordance with ACIM, our main purpose is always to awaken from the dream of the vanity earth and come back to the consciousness of our heavenly nature.

ACIM also presents the thought of the Sacred Spirit as helpful tips and instructor within the individual. That religious presence sometimes appears as the origin of inspiration and wisdom, helping us make acim choices that cause people closer to reality and from illusion. The Program shows that through our readiness to listen to the Sacred Spirit's guidance, we can entry a greater comprehension of our purpose and the path to healing.

The Book for Students in A Class in Wonders includes 365 lessons, one for each time of the year. These lessons are made to support pupils internalize the teachings and use them to their everyday lives. They often include meditative and contemplative exercises, affirmations, and reflections on the concepts shown in the text.

The Guide for Teachers, the next element of ACIM, is directed at those individuals who have embraced the concepts of the Class and feel compelled to fairly share them with others. It provides advice on the characteristics of a real instructor of Lord, focusing characteristics such as patience, trust, and an open heart. It acknowledges the difficulties and obstacles one may experience while training the Class and offers ideas on how best to understand them.
