At the key of A Class in Wonders is a non-denominational way of spirituality that encourages pupils to issue their preconceived notions about reality, the self, and the world. The text is divided into three areas: the Text, the Book for Students, and the Handbook for Teachers, each offering a unique perspective on the material presented. The key teachings of ACIM could be distilled in to a few key principles.

One of many key styles of ACIM is the idea of forgiveness. The Program teaches that forgiveness isn't simply pardoning some body due to their wrongdoings, but rather, it is the recognition that there's nothing to forgive. It asserts that what  a course in miracles  we comprehend as wrongdoings are fundamentally the consequence of our personal misperceptions and projections. In flexible others, we're, in reality, forgiving ourselves. ACIM highlights that forgiveness is a way to internal peace and liberation from the burdens of resentment and anger.

Still another basic theory of A Program in Wonders is the proven fact that the bodily world is definitely an illusion. It posits that our sensory experiences are unreliable signs of truth and that correct notion can only be achieved through a shift in consciousness. The Program distinguishes involving the "real life," which is really a state of peace and oneness beyond the material region, and the "ego world," indicated by concern, separation, and conflict. In accordance with ACIM, our principal function is to awaken from the desire of the pride world and return to the recognition of our divine nature.

ACIM also introduces the notion of the Sacred Nature as helpful information and teacher within the individual. That spiritual presence is seen as the origin of enthusiasm and knowledge, supporting us produce possibilities that lead us closer to truth and away from illusion. The Program shows that through our willingness to listen to the Holy Spirit's guidance, we can entry a deeper comprehension of our function and the road to healing.
