One of the main themes of ACIM is the idea of forgiveness. The Class teaches that forgiveness is not merely pardoning some one due to their wrongdoings, but alternatively, it is the acceptance that there's nothing to forgive. It asserts that what we perceive as wrongdoings are ultimately the result of our personal misperceptions and projections. In flexible others, we are, in fact, forgiving ourselves. ACIM highlights that forgiveness is really a path to inner peace and liberation from the burdens of resentment and anger.
Another fundamental principle of A Course in Wonders may be the proven fact that the bodily world is an illusion. It posits our physical activities are unreliable signs of truth and that true notion can just only be performed through a shift in consciousness. The Program distinguishes between the "real-world," which is really a state of peace and oneness beyond the product world, and the "vanity earth," indicated by concern, separation, a course in miracles conflict. According to ACIM, our major purpose would be to awaken from the dream of the ego earth and come back to the consciousness of our heavenly nature.
ACIM also introduces the idea of the Sacred Spirit as a guide and instructor within the individual. That religious existence is seen as the origin of creativity and wisdom, supporting us make choices that lead people nearer to reality and away from illusion. The Program teaches that through our readiness to be controlled by the Sacred Spirit's guidance, we can access a deeper knowledge of our purpose and the way to healing.
