A Course in Miracles teaches us that all illness is mental illness and health is inner peace. The deceived mind reacts to the images of the world as if they are real. The Holy Spirit has the job of convincing the mind that it is dreaming and that the illness is actually our fragmented perception and not in the world.
The world we perceive is only our animated thoughts projected outward. With the Holy Spirit’s vision we begin to awaken from the dream and recognize that all healing is done on the level of the mind, where true healing can actually occur.
