The law is subject to Spirit, which does not mean that Spirit is capricious and may create a law only to break it, but does mean that law is subject to Spirit, in that the law is Spirit’s servant, just as all the laws of nature are our servants and obey us insofar as we understand them and properly use them. Spirit, being Omniscient, understands and properly uses all law. Hence, Spirit never contradicts Its own nature, is always harmonious, is complete within Itself; It exists in a state of perpetual bliss and always acts in accord with the law of Its own being.
We are of like nature to this supreme Spirit. Everything exists within It. We exist within It, having arrived at a state of consciousness whereby we can consciously approach It, believe in It, and receive It. In receiving Spirit, we receive the law which is Its servant, and that law becomes our servant.
We are intelligent beings living in an intelligent universe that responds to our mental states, and insofar as we learn to control those mental states, we shall automatically control our environment. This is what is meant by the practical application of the principles of Science of Mind to the problems of everyday living. This is what is meant by demonstration.
Naturally our first thought is that we would like to demonstrate health of body, peace of mind, prosperity in our affairs, to neutralize a circumstance which is unhappy, or to attract to ourself some good which we have not been enjoying. Such a desire is natural and in every way normal, and the possibility of such demonstration already exists within the mind of every living soul. Every one of us has within ourself the power to consciously cooperate with the spiritual side of our existence in such a way that it will create for us a new body and a new environment and a greater happiness. But the greatest good which this philosophy of life brings to us is a sense of certainty, a sense of the reality of our own soul, of the continuity of our own individualized being, and the relationship of this self to the great Whole.
