Says one of deep insight into the nature of things: "The law of correspondences between spiritual and material things is wonderfully exact in its workings. People ruled by the mood of gloom attract to them gloomy things. People always discouraged and despondent do not succeed in anything, and live only by burdening some one else. The hopeful, confident, and cheerful attract the elements of success. A man's front or back yard will advertise that man's ruling mood in the way it is kept. A woman at home shows her state of mind in her dress. A slattern advertises the ruling mood of hopelessness, carelessness, and lack of system. Rags, tatters, and dirt are always in the mind before being on the body. The thought that is most put out brings its corresponding visible element to crystallize about you as surely and literally as the visible bit of copper in solution attracts to it the invisible copper in that solution. A mind always hopeful, confident, courageous, and determined on its set purpose, and keeping itself to that purpose, attracts to itself out of the elements things and powers favorable to that purpose. "Every thought of yours has a literal value to you in every possible way. The strength of your body, the strength of your mind, your success in business, and the pleasure your company brings others, depends on the nature of your thoughts. . . . In whatever mood you set your mind does your spirit receive of unseen substance in correspondence with that mood. It is as much a chemical law as a spiritual law. Chemistry is not confined to the elements we see. The elements we do not see with the physical eye outnumber ten thousand times those we do see. The Christ injunction, 'Do good to those who hate you,' is based on a scientific fact and a natural law. So, to do good is to bring to yourself all the elements in nature of power and good. To do evil is to bring the contrary destructive elements. When our eyes are opened, self-preservation will make us stop all evil thought. Those who live by hate will die by hate: that is, 'those who live by the sword will die by the sword.' Every evil thought is as a sword drawn on the person to whom it is directed. If a sword is drawn in return, so much the worse for both."
