Keely
"So stood matters with Mr. Keely until a few years ago, when, fortunately for his hopes of success, a new conception came to him by accident, as he asserts; one of those happy accidents, it would appear, which only men of the unusual capacity called genius are ready to take advantage of. Just what this conception was, Mr. Keely, with business-like caution, keeps to himself. The public, for the present at least, must be content with its visible results; but these are sufficiently noteworthy to amply repay consideration. They indicate two things: First, that Mr. Keely is no longer dealing with a power arising from gaseous pressure; and, second, that he has made this power capable of producing rotation, levitation, and other effects of mechanical energy. What he claims, in regard to the source of his new system of power, is that he is able to draw vibratory energy directly from space by the aid of special resonating expedients, and that this energy can be made to yield powerful attractive and repulsive force and be converted into vigorous rotary motion through the use of certain apparatus. The power obtained, he asserts, is duplex, or has two opposed conditions, like the positive and negative states of electricity. Mr. Keely denominates these conditions positive and negative, though with the reservation that these terms do not imply excess and deficiency, but simply opposite conditions of energy. He is able, he declares, to disturb the equilibrium of these opposed states of vibratory activity as they exist in the elements of nature, to draw them separately into his apparatus, and to produce mechanical motion as a result of the effort of nature to restore the disturbed equilibrium."

Radiation is the bipolar unity, the ur-information, which metamorphoses itself into proteins. Since information is also bipolar, then the space, the irtter-space and the shell come into being in this way. The energy evolving within the shell is space-energy, which like everything else is also bipolar. The heat-potential gives birth to the form and the cold-potential gives rise to dematerialisation. The latter is elemental motion and the former is the elemental envelope, that is, the multiplied soul and the multiplied body.
