"Reception and dispersion are kept up on the atmospheric envelope of the earth by the atomic and interatomic conflict as "between the dominant and the enharmonic". This is brought about by the reception and dispersion of sympathetic streams, the ruling mode of whose vibration is the dominant, and the density of the coarser grades of matter, whose ruling vibratory mode is the enharmonic.
As every mass consists of vibrations in thirds, balanced in harmonic equilibrium without cancellation or diminution of energy, it stands therefore in harmonic relation to every other mass. All forms of matter and of motion are thus interrelated and interchangeable. Through resonance, increasing this sympathy, we can control the states of matter." [Mass Action, Snell Manuscript - the book]
Every mass is an aggregation of molecules each having its "neutral center" wherein are equated its component forces consisting of the three fundamental modes of vibration. The balanced activity of these vibrations at the "neutral center" without diminution of force, makes possible the permanence of form and matter.
Since the continuity of existence of all molecules and all masses depends on the three fundamental component modes of vibration being held in balance at the "neutral center" it follows that certain orders of vibration can, by their influence on this neutral center, break the balanced equation, divide the components of the molecules, and therefore divide the components of the mass.
