Spirit energy animates the body without which the body would have no motion or life. Spirit then, would be in scientific terms, an ever increasing degree of harmonicity ala the Bjerknes Effect acting within the higher interetheric realms which of course permeates all lower realms as well. There will be more discussion on this dynamical principle in later Parts to this work.
"Likewise the body of man does not live, and having never lived it cannot die.
"The spirit alone lives. The body but manifests the spirit. That which we think of, as life in the spirit of man manifests itself by willing the body to act." [Russell]
What Russell is saying, is the physical/material body does not have anything of and in it to animate itself. Matter is inert unless animated by some force and energy. Like an automobile cannot move without Electricity in its wires and fuel in its engine. In the human body the animating force comes from spirit which as we now know is the same as and acts within Keely's interetheric realm of matter/energy. This is also the mana of the ancients. This process is encompassed in currents of Keely's sympathetic streams. And now with an explanation we can see Russell was absolutely correct.
"The spirit is the impelling influence of infinity, or the one creative source, force, that is manifest. ... spirit is the life-giving force in every condition, whether of mental or material action." Cayce (5749-3)
"Spirit is the vibrating energy which underlies the manifestations of all matter." Harvey Spencer Lewis
"Mr. Keely affirms, with other philosophers, that there is only one unique substance, and that this substance is the Divine spirit of life, and that this spirit of life is God, who fills everything with his thoughts, disjoining and grouping together these multitudes of thoughts in different bodies called atmospheres, fluids, matters, animal, vegetable, and mineral forms." [Bloomfield-Moore See Etheric Elements]
"Spirit is the First Cause. Mind is an effect, or an active force that partakes of spiritual as well as material import. Mind is an essence or a flow between Spirit and that which is made manifest materially.
"God, the First Cause, in spirit, created in spirit the separate influences or forces that are a portion of, and manifested in the spirit of, God. In that essence, to become materially manifested through the evolution of the spirit of God, sin first began.
"The first concept as may be had of that in materiality is that it is an essence, without form, save as it begins to manifest, - as would be gas, odor, wind, smoke, - yet that it has with it the will, the mind, the power to make manifest by that with which, in which, it manifests, - as does also odor, gas, wind and the like. [See Etheric Elements]
"Thus - as the activities came - we may assume that the First Cause was Spirit, Mind, Will." [Cayce (262-123)]"Hence, in the fruits of that - as is given oft, as the fruits of the spirit - does man become aware of the infinite penetrating, or inter-penetrating the activities of all forces of matter, or that which is a manifestation of the realm of the infinite into the finite - and the finite becomes conscious of same." [Cayce (262-52) see Celestial Radiation]
