A person's thoughts control his body just as surely as a computer program controls a computer. But because conscious control of the body is limited by mortal mind's own beliefs about the body, it may be hard to believe that one's thinking totally determines his bodily condition.
The human body seems to be a self-acting entity, producing either sickness or health and reacting to outside influences over which the individual appears to have little control. Yet in the Christian Science textbook, Science and Health, Mrs. Eddy says, "Science shows that what is termed matter is but the subjective state of what is termed by the author mortal mind."Science and Health, p. 114; The body is not a physical entity being programmed by a mortal mind apart from itself. The so-called mortal mind and material body are one. And neither the material body nor the mortal thinking is the real man.
The real man is more—infinitely more—than a mind-matter identity. Man is God's own image, the image of Spirit. Therefore man is not made up of material substance called flesh and bones. He is the embodiment of God's ideas, and these ideas constitute his true being, spiritual and perfect.
