Still another essential theory of A Program in Wonders may be the indisputable fact that the physical world is definitely an illusion. It posits that our sensory experiences are unreliable indications of fact and that true belief can just only be achieved through a shift in consciousness. The Course distinguishes between the "real life," which is a state of peace and oneness beyond the substance sphere, and the "ego world," indicated by concern, separation, and conflict. Based on ACIM, our principal purpose is always to wake from the desire of the pride world and come back to the awareness of our heavenly nature.

ACIM also presents the idea of the Sacred Heart as helpful information and teacher within the individual. This religious existence sometimes appears as the source of inspiration and knowledge, helping acim people make possibilities that lead people nearer to truth and far from illusion. The Program teaches that through our readiness to listen to the Holy Spirit's guidance, we are able to entry a further comprehension of our purpose and the way to healing.

The Workbook for Students in A Class in Wonders consists of 365 instructions, one for each time of the year. These classes are made to support pupils internalize the teachings and use them for their everyday lives. They often contain meditative and contemplative exercises, affirmations, and insights on the ideas shown in the text. The goal of these everyday instructions is to change the student's understanding and mind-set gradually, major them towards circumstances of correct forgiveness, internal peace, and religious awakening.

The Manual for Teachers, the third part of ACIM, is targeted at those individuals who have embraced the rules of the Class and experience forced to generally share them with others. It gives advice on the characteristics of a real instructor of Lord, emphasizing characteristics such as for instance patience, confidence, and an open heart. It acknowledges the challenges and obstacles one may encounter while training the Class and presents ideas on the best way to understand them.
