In his original work this summary is based upon; Robert Collier tells us, “The truth will set you free.” This basically means that all right ideas come from Universal Mind, otherwise known as God. He says that Evil and ill health are the result of Universal Mind being used incorrectly, if at all.
Like the principles we use in solving math problems; the Principle of Universal Mind is changeless. Therefore, according to Collier, the only power is mind. The troubles without come from within. The fear you have within will manifest itself in your physical reality. Disease is the result of losing touch with Universal Mind. So are poverty and other forms of lack.
If you can see yourself as being healthy you will eventually find that you improve your health. If you see yourself as aging, you will age. In short; your body will become what you perceive it to be.
See yourself as the person you want to be and believe that you have it within yourself to be so already. Then, by keeping this image of yourself clearly in your mind’s eye, you will become the man or woman you see in your mental image.
