Still another simple principle of A Program in Wonders is the proven fact that the physical world is an illusion. It posits which our sensory activities are unreliable indications of truth and that correct perception can only be achieved through a shift in consciousness. The Class distinguishes between the "real life," which is really a state of peace and oneness beyond the product sphere, and the "vanity world," characterized by concern, divorce, and conflict. Based on ACIM, our main purpose is to wake from the dream of the pride world and return to the awareness of our divine nature.

ACIM also presents the thought of the Holy Soul as helpful tips and teacher within the individual. This religious existence is seen as the source of creativity and knowledge, helping people produce choices that cause people closer to truth and away from illusion. The Program a course in miracles shows that through our readiness to hear the Holy Spirit's guidance, we can access a greater understanding of our purpose and the road to healing.

The Book for Students in A Program in Miracles contains 365 classes, one for each day of the year. These lessons are designed to help students internalize the teachings and apply them for their everyday lives. They usually include meditative and contemplative exercises, affirmations, and insights on the methods shown in the text. The purpose of these day-to-day classes is always to change the student's notion and mind-set steadily, leading them towards circumstances of correct forgiveness, internal peace, and religious awakening.

The Guide for Educators, the next component of ACIM, is targeted at those who have embraced the rules of the Class and feel forced to fairly share them with others. It gives guidance on the traits of a genuine teacher of God, emphasizing characteristics such as for example persistence, trust, and an start heart. It acknowledges the challenges and limitations one may encounter while teaching the Class and presents insights on the best way to navigate them.
