"I assume that sound, like odor, is a real substance of unknown and wonderful tenuity, emanating from a body where it has been induced by percussion, and throwing out absolute corpuscles of matter - interatomic particles - with a velocity of 1120 feet per second, in vacuo 20,000. The substance which is thus disseminated is a part and parcel of the mass agitated, and if kept under this agitation continuously would, in the course of a certain cycle of time, become thoroughly absorbed by the atmosphere; or, more truly, would pass through the atmosphere to an elevated point of tenuity corresponding to the condition of subdivision that govern its liberation from its parent body. The sounds from vibratory forks, set so as to produce etheric chords, while disseminating their compound tones permeate most thoroughly all substances that come under the range of their atomic bombardment. The clapping of a bell in vacuo liberates these atoms with the same velocity and volume as one in the open air; and were the agitation of the bell kept up continuously for a few millions of centuries, it would thoroughly return to its primitive element. If the chamber were hermetically sealed, and strong enough, the vacuous volume surrounding the bell would be brought to a pressure of many thousands of pounds to the square inch, by the tenuous substances evolved. In my estimation, sound truly defined is the disturbance of atomic equilibrium, rupturing actual atomic corpuscles; and the substance thus liberated must certainly be a certain order of etheric flow. Under these conditions is it unreasonable to suppose that, if this flow were kept up, and the body thus robbed of its element, it would in time disappear entirely? All bodies are formed primitively from this high tenuous ether, animal, vegetal and mineral, and they only return to their high gaseous condition when brought under a state of differential equilibrium." [Keely in More Science]
"Taking into consideration even the introductory conditions of the etheric stage, etheric vibration has proved to me that the higher the velocity of its rotating stream the greater is its tendency towards the neutral centre or centre of sympathetic coincidence. Were it otherwise, how could there ever be any planetary formations of the building up of visible structure? If a billiard ball were rotated to a certain velocity, it would separate in pieces, and the pieces would fly off in a tangent; but if it were a ball of ether, the higher the velocity of rotation the stronger would be the tendency of its corpuscules to seek its centre of neutrality, and to hold together."

"On this subject Mr. Keely writes: - "Every disease that the physical organism is subject to has its connective link in the cerebral domain; where it unerringly telegraphs, as it were, its molecular differentiations, through the spinal dura mater or physical sympathetic transmitter, and vice versa back again. The sympathetic communication, as between the physical and mental forces, shows up truthfully the pure conditions that govern the celestial and terrestrial link of sympathy, as between the finite and the Infinite in planetary suspension. The whole system governing the suspension of the innumerable planetary masses, - the infinite certainly and harmony of their eccentric evolution and revolution, in their orbital and oscillating ranges of motion, - the triune sympathetic streams of Infinity that permeate their molecular masses - focalizing and defocalizing on their neutral centres of attraction - are all subservient to that Great Ruling Power: Mind Flow. There is not a grain of sand, nor an invisible corpuscle of floating matter, that does not come under the same rule that governs the most mighty of planets. . . ."

"Corpuscles are inconceivably small particles of matter, or light, or Mind substance, which have been churned into motion by the electromagnetic forces of the thinking process of Mind, exactly as bubbles are particles of water and air churned into motion by the force of a propeller.
"As it should also by now be thoroughly understood that the words "matter" and "light" are used in the sense of characterising the substance of Mind, and that the word "energy" is used in the sense of characterizing the force, or life principle which makes of Mind a thinking substance; that the words "electricity" and "magnetism" are used in the sense of characterizing the apparent division of the One force of energy into the appearance of two, the relator will henceforth use these words with the assurance that the line between reality and illusion has been sufficiently well drawn to justify the omission of qualifying words." [The Universal One, Book 02 - Chapter 01 - Dynamics of Mind - Concerning Light Units of Matter]
"From the definition of energy it is the potential of the Universe. When matter is in a phase allowing it to be active, it effects other quantities of matter at a distance. The method of transfer is known to be by means of wave motion. Each impulse moves from the omitting to the receiving mass on a rigorously straight line. One continuous set of oscillations in this right line is called a ray. Each negative or Thomsonian corpuscle makes a double vibration to and fro like a pendulum straight across the direction of the ray; i.e., at right angles to it, the corpuscles moves over and returns to its original position it had before the excursion. Since the corpuscles are negative and can be drawn out of their original straight path by the action of magnetism, the entire wave motion of the Universe is electro-magnetic. This is what Maxwell prophesied many years ago. Thomson fulfilled the prophecy." [source unknown]
