Taking the above two quotes we can deduce roughly: A Longitudinal wave is in straight lines (to and fro), this we know. This motion is same as the Infinite Ninths Harmonic Series and is therefore concordant and attractive or syntropic. At some point in its scale evolution (probably 3rd octave where musical thirds and fourths first appear) there is developed discordant overtones (Summation and Difference Tones) which act as Transverse waves moving in a zig-zag (side to side) motion. These are developed by the Law of Cycles and are discordant to the first Longitudinal series and motions. These two motions acting in concert create an additional third motion of Rayleigh Wave or Love waves which is circular or rotating. Keely then says this rotating motion, when considered as a stream, is sympathetically coincident (and therefore attractive) to etheric centers. Such logic would further imply these three streams or conditions of "Locked Potentials" are not fixed absolutely but may be forced into varying degrees of coincidence. These variations would be highly unstable and if amplified beyond a certain point would disrupt (dissociate) the structure.

So these two conditions of Harmony and Discord are the two great sexes or opposites that when considered together, AS ONE, also evidence a third condition. It is to be understood, as Professor Daniel Brinton wrote, these three conditions are never separate or individual by themselves but are always together even though one or two modes are less or not evident at all - and being latent - may be brought out by sympathetic stimulation.
