In the final analysis, all things in Nature, from a fleeti g thought or emotion to the hardest piece of diamond or platinum, are modes of motion or vibration. A few years ago physical science assumed that an atom was the smallest imaginable part of a given element of matter; that although infinitesimally small, it still represented solid matter. Now, in the light of better evidence, we have good reason to believe that there is no such thing as solid matter: that every atom is made up of charges of negative and positive electricity acting in and upon an omnipresent ether; that the difference between an atom of iron and of hydrogen or any other element consists solely in the number of electrical charges or corpuscles it contains, and on the velocity with which these vibrate around one another.

Thus the atom, which was thought to be the ultimate particle of solid matter, is found to be a little universe in itself in which corpuscles of electricity rotate or vibrate around one another like the suns and planets in the sidereal universe. This explains what we mean when we say life and matter are vibratory.

As early as 1863 John Newlands discovered that when he arranged the elements of matter in the order of their atomic weight, they displayed the same relationship to one another as do the tones in the musical scale. Thus modern chemistry demonstrates the verity of the music of the spheres--another visionary concept of ancient mysticism. The individual atoms in themselves, as well as all the atoms of matter in their relationship to one another, are constructed and arranged in exact correspondence with the laws of harmony. Therefore the entire sidereal universe is built on the laws of music.

That which is orderly, lawful, good, beautiful, natural, healthy, vibrates in unison with the harmonics of this great "Diapason of Nature"; in other words, it is in alignment with the constructive principle in Nature.

That which is disorderly, abnormal, ugly, unnatural, unhealthy, vibrates in discord with Nature's harmonics. It is in alignment with the destructive principle in Nature.

What we call "Inanimate Nature" is beautiful and orderly because it plays in tune with the score of the Symphony of Life. Man alone can play out of tune. This is his privilege, if he so chooses, by virtue of his freedom of choice and action.

We can now better understand the definitions of health and of disease, given in Chapter Two, "Catechism of Nature Cure" as follows:

"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.
