Have you ever noticed how the written or printed notes of a tone piece or the perforations on the paper music roll of an automatic player are arranged in symmetrical and geometrical figures and groups? Dry sand strewn on the top of a piano on which harmonious tone combinations are produced shows a tendency to arrange itself in symmetrical patterns. In this you have a visual illustration of the translation of harmonious sound vibrations, which express the harmonics of the soul's emotions, into correspondingly harmonious arrangements and configurations in the physical material of the paper roll. A jumble of discords of sound, if reproduced on a music roll, would present a chaotic jumble of perforations. Thus the purely mental and emotional is translated into its corresponding discords or harmonies in the physical. As the perforations on the paper music roll arrange themselves either symmetrically or without symmetry and order, in strict accordance with the harmonies or discords of the composition, so the atoms, molecules and cells in the physical body group themselves in normal or abnormal structures of health or of disease in exact correspondence with the harmonious or the discordant vibrations conveyed to them from the mental and emotional planes. Another Illustration: Two violins, as they leave the shop of the maker, are exactly alike in material, structure and quality of tone. One of the two instruments is constantly used by beginners and persons incapable of producing pure notes. The other passes into the hands of an artist who understands how to use the instrument to the best advantage and who draws from it only musical tones that are true in pitch and quality. After a few years, compare the two violins again. You will find that the one used by the tyros in music has deteriorated in its musical qualities, while the one in the hands of the artist has greatly improved in quality and purity of tone. What is the reason? The atoms and molecules in the wood of the two instruments have grouped themselves according to the discords or the harmonies that have been produced from them. If this rearrangement of atoms is possible in dead wood, how much easier must be this adjustment of atoms, molecules and cells to discordant or harmonious vibratory influence in the living, plastic and fluidic human organism! What harmony is to music, hope, faith, cheerfulness, happiness, sympathy, love and altruism are to the vibratory conditions of the human entity. These emotions are in alignment with the constructive principle in Nature. They harmonize the physical vibrations, relax the tissues and open them wide to the inflow of the life force.
