What may perhaps not have been made clear is these two flows operate in mutual antagonism/cooperatism one to and with the other. Russell referred to them as the Father (syntropy) and Mother (entropy) progenitor conditions of all waves.
"The father-mother principle is fundamental in every expression and both are simultaneously manifested in every expression, each being preponderant sequentially during half of each cycle." Russell, The Secret of Light, page 125
The Syntropic and Entropic principles are linked together as two oxen may be yoked together pursuing a common direction but individual unto each themselves. What tells the difference is PREPONDERANCE. Whichever pole, state or condition PREPONDERATES within the whole of the pair dictates how the wave will behave AS A WHOLE. Keely's ((14.35.1 - Keely 3 6 and 9|Thirds, Sixths and Ninths)) ratios refers to the degree or proportion of preponderance. This is what I've been referring to with the phrase "differential densities". A change in the preponderance will result in either contraction to a center (formation of matter) or dispersion away from the center (dissociation of matter). A preponderance of the syntropic will form matter. A preponderance of the entropic will dissociate matter. But both states are always present in every wave. Preponderance is regulated by the etheric current known as the Dominant. It must be kept in mind these poles, states or conditions are not two separate things but two conditions of the same thing - a wave, vibration or oscillation. Conventional science tends to view the phases of a wave as separate actions but they are in fact two seemingly different actions of the same wave. See more on this in Part 09 - What Vibration Is. - Part 2, Laws of Being, Modes of Vibration.
