"Health is normal and harmonious vibration of the elements and forces composing the human entity on the physical, mental, moral and spiritual planes of being, in conformity with the constructive principle of Nature applied to individual life."
"Disease is abnormal or inharmonious vibration of the elements and forces composing the human entity on one or more planes of being, in conformity with the destructive principle of Nature applied to individual life."
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).
