The question naturally arising here is, "Normal or abnormal vibration with what?" The answer is that the vibratory conditions of the organism must be in harmony with Nature's established harmonic relations in the physical, mental, moral, spiritual and psychical realms of human life and action. What Is an Established Harmonic Relation? Let us see whether we cannot make this clear by a simile. If a watch is in good condition, in harmonious vibration, its movement is so adjusted that it coincides exactly, in point of time, with the rotations of our earth around its axis. The established, regular movement of the earth forms the basis of the established harmonic relationship between the vibrations of a normal, healthy timepiece and the revolutions of our planet. The watch has to vibrate in unison with the harmonics of the planetary universe in order to be normal, or in harmony. In like manner, everything that is normal, natural, healthy, good, beautiful must vibrate in unison with its correlated harmonics in Nature. Obedience the Only Salvation Orthodox medical science attributes disease largely to accidental causes: to chance infection by disease taints, germs or parasites; to drafts, chills, wet feet, etc. The religiously inclined frequently attribute disease and other tribulations to the arbitrary rulings of an inscrutable Providence. Christian Scientists tell us that sin, suffering, disease and all other kinds of evil are only errors of mortal mind, or the products of diseased imagination (though this in itself admits the existence of something abnormal or diseased). Nature Cure philosophy presents a rational concept of evil, its cause and purpose, namely: that it is brought on by violation of Nature's Laws; that it is corrective in its purpose; that it can be overcome only by compliance with the law. There is no suffering, disease or evil of any kind anywhere unless the law has been transgressed somewhere by someone. These transgressions of the law may be due to ignorance, to indifference or to wilfulness and viciousness. The effects will always be commensurate with the causes. The science of natural living and healing shows clearly that what we call disease is primarily Nature's effort to eliminate morbid matter and to restore the normal functions of the body; that the processes of disease are just as orderly in their way as everything else in Nature; that we must not check or suppress them, but cooperate with them. Thus we learn, slowly and laboriously, the all-important lesson that "obedience to the law" is the only means of prevention of disease, and the only cure.
