Still another simple theory of A Class in Miracles is the idea that the physical earth is definitely an illusion. It posits our physical activities are unreliable indicators of reality and that correct perception can only be performed through a shift in consciousness. The Course distinguishes involving the "real world," which is a state of peace and oneness beyond the material kingdom, and the "confidence earth," known by concern, divorce, and conflict. In accordance with ACIM, our primary function is always to awaken from the desire of the pride world and return to the awareness of our divine nature.

This spiritual presence sometimes appears as the source of motivation and knowledge, helping us make possibilities that cause people closer to reality and ACIM Videos  illusion. The Course teaches that through our readiness to be controlled by the Holy Spirit's guidance, we are able to access a greater understanding of our purpose and the road to healing.
