Such are the crowding thoughts, born of interior knowledge, that flood the mind as we view these sacred revelations within the sacred chamber of the soul. As yet, we are gazing upon the undulating flow of the astral light. We yearn within our utmost being to become the center of the Penetralia and gaze upon the glorious radiance of the Adonai, from whose ineffable presence we are only screened by the last shining veil of semi-transparent matter, that waves and trembles with every spiritual aspiration. The soul sends forth its pleading cry for light: "Who and what is God?" Faintly, as the distant vesper sounds upon the cooling eve, comes the answer: "Who and what art thou? What canst thou see? What delectable blessing does Nature vouchsafe to the pure in heart?" We tremble with the awful, yet thrilling, revelation. We know dimly, yet fail to realize in our outward consciousness the full import thereof. We realize wherein the mistaken selfhood hath become the only begotten of the Father, but the revelation is too much, and too little. We know that, faint as the voice seemed to the yet unprepared soul, an echo only, IT WAS THE VOICE OF THE ADONAI BEHIND THE VEIL. And now we crave the knowledge of the Where and Whither. Again, we see the Earth as the vital function of the interplanetary being. It is composed of substance termed matter, which substance is the aggregation of countless atoms, which science has not, and never can, resolve into their individual selves. These atoms are rings of the atomless ether, which, thus differentiated from the formless ether, become centers of force, the center of such force being a vacuum within the atomic ring--a center so small that a microscope with lens one thousand times as powerful as the most perfect modern instrument would fail to reveal it. These atoms form systems, under the control of another apparent vacuum; or, rather, this vacuum seems to be the focus, or center, about which they revolve. THIS SYSTEM CONSTITUTES A SCIENTIFIC MOLECULE OF MATTER, and, in response to the innumerable vibrations, they assume different forms or dimensions, and become, indifferently, molecules of oxygen, hydrogen, nitrogen, or carbon, as the case may be, all of which are but different modes of motion of the same primitive atoms, there being in Nature but three things--Ether, Intelligence, and Motion. What Ether is, no one knows. We call it the formless spirit, the unmanifest, etc. But, there can be no doubt but, that Motion is the product of Intelligence, since we never see Motion but as the manifestation of evolution, and this is the expression of Mind. Therefore, we have a duality--Ether and Intelligence; one the living spirit, the other the eternal substance for its manifestation.
