Keely
"Life begets life; the celestial life begets the terrestrial life; the God life begets the man life. Celestial Radiation is the pure soul of all matter, both earthy and gaseous. Thus we are linked in all our environments to the divine, our cerebral aggregations being the highest medium whereby celestial sympathetic reflection associates with our organisms, and is our only source of knowledge of ourselves. We have, with our mental and physical forces, a duality of action which, when combined with the celestial, makes up the triplet or trinity. With the mental, the superficial visible, or outward sight; with the inward, or spiritual invisible, we have the spiritual link connecting mind and matter, the order of transfer being:

"First. Celestial Radiation, or etheric.
"Second. Mental impregnation, or interatomic.
"Third. Physical movements, or intermolecular.

Or again:

"Ninths. Sympathetic transfer from the celestial luminous.
"Sixths. Sympathetic impregnation of matter.
"Thirds. Physical movements." [Newton of the Mind]

"The sympathetic acoustic impulses are: 

"the DOMINANT - a diatonic third - 

"the HARMONIC - the connective "sixth" - and 

"the ENHARMONIC - or diminished seventh - which Keely calls a ninth - 

"inducing "infinite trajective velocity" or "neutral radiation" from neutral centers. [Snell Manuscript]
