Yet another basic theory of A Course in Miracles may be the idea that the physical world is an illusion. It posits that our physical activities are unreliable indications of truth and that correct notion can just only be achieved via a shift in consciousness. The Program distinguishes involving the "real-world," which is a state of peace and oneness beyond the material region, and the "confidence world," indicated by anxiety, divorce, and conflict. Based on ACIM, our principal purpose is to wake from the dream of the confidence world and go back to the understanding of our heavenly nature.

ACIM also introduces the thought of the Sacred Soul as a guide and instructor within the individual. That spiritual existence is observed as the origin of inspiration acim and wisdom, helping us make possibilities that lead us closer to truth and from illusion. The Class shows that through our willingness to listen to the Sacred Spirit's advice, we could entry a deeper comprehension of our function and the way to healing.

The Book for Students in A Course in Miracles includes 365 lessons, one for every time of the year. These lessons are created to support students internalize the teachings and apply them with their daily lives. They usually contain meditative and contemplative exercises, affirmations, and insights on the ideas shown in the text. The purpose of these daily classes is to change the student's understanding and mind-set gradually, major them towards a state of correct forgiveness, internal peace, and spiritual awakening.

The Handbook for Educators, the 3rd component of ACIM, is targeted at those people who have embraced the axioms of the Class and sense compelled to fairly share them with others. It gives advice on the features of a genuine instructor of God, emphasizing characteristics such as patience, trust, and an open heart. It acknowledges the difficulties and limitations one might experience while training the Course and offers ideas on how to understand them.
