"This result is the all-pervading spirit of space (the ether of mankind), as solid as adamant and as mobile as vacuity. If you can reverse the order of this phenomenon, and imagine an irregular retardation of the rapidity of such atomic motion, you can read the story of the formation of the material universe. Follow the chain backward, and with the decrease of velocity, motion becomes tangible matter again, and in accordance with conditions governing the change of motion into matter, from time to time the various elements successively appear. The planets may grow without and within, and ethereal space can generate elemental dirt. If you can conceive of an intermediate condition whereby pure space motion becomes partly tangible, and yet is not gross enough to be earthy matter, you can imagine how such forces as man is acquainted with, light, heat, electricity, magnetism, or gravity even are produced, for these are also disturbances in space motion. It should be easily understood that, according to the same simple principle, other elements and unknown forces as well, now imperceptible to man's limited faculties, could be and are formed outside and inside his field of perception." "I fear that I can not comprehend all this," I answered. "So I feared, and perhaps I have given you this lesson too soon, although some time ago you asked me to teach you concerning the assertion that electricity, light, heat, magnetism, and gravity are disturbances, and you said, 'Disturbances of what?' Think the lesson over, and you will perceive that it is easy. Let us hope that the time will come when we will be able to glance beneath the rough, material, earth surface knowledge that man has acquired, and experience the mind expansion that leads to the blissful insight possessed by superior beings who do not have to contend with the rasping elements that encompass all who dwell upon the surface of the earth."
