Still another simple theory of A Course in Miracles is the proven fact that the physical earth is an illusion. It posits that our sensory experiences are unreliable signs of truth and that correct perception can only be performed through a change in consciousness. The Course distinguishes between the "real-world," which really is a state of peace and oneness beyond the product sphere, and the "ego world," characterized by fear, separation, and conflict. Based on ACIM, our major purpose would be to wake from the dream of the ego world and come back to the recognition of our divine nature.

ACIM also presents the thought of the Holy Soul as a guide and teacher within the individual. That spiritual existence is seen as the foundation of inspiration and wisdom, helping us make possibilities acim that lead us closer to reality and far from illusion. The Class shows that through our willingness to be controlled by the Holy Spirit's guidance, we could access a deeper understanding of our function and the way to healing.

The Workbook for Students in A Class in Wonders contains 365 lessons, one for every single time of the year. These lessons are made to help pupils internalize the teachings and apply them to their daily lives. They often contain meditative and contemplative exercises, affirmations, and insights on the concepts presented in the text. The purpose of these everyday lessons would be to change the student's notion and mindset slowly, major them towards a state of true forgiveness, internal peace, and spiritual awakening.

The Guide for Educators, the third component of ACIM, is directed at those who have embraced the principles of the Course and experience required to generally share them with others. It gives guidance on the characteristics of a real instructor of God, focusing features such as for example patience, confidence, and an start heart. It acknowledges the problems and limitations one might encounter while teaching the Program and offers ideas on the best way to steer them.
