"The remaining work on the device is finished by painting the interior of the globe, one hemisphere black and one white, and attaching a rubber bulb such as is used to spray perfume, to the hollow end of the shaft. This bulb equates vibratory undulations, thus preventing an equation of molecular bombardment on its dark side when sympathetically influenced. It is now in condition to denote the sympathetic concordance between living physical organisms, or the receptive transmittive concordance necessary to induce rotation."

"As a first step we again remind you that Nature creates everything in pairs, and that all pairs unite to form masses. The hemispheres of a sun are united pairs, for example. Try, therefore, as a first mental exercise, to image the uniting of two hemispheres of the sun, which are spinning in opposite directions. The fact that you, yourself, are right-handed and left-handed, adds to the difficulty of the subtle thing which we must explain about our universe, which has led these observers to form such conclusions. What we mean by this is that Nature is bilateral. Everything which is created is equally extended in pairs from a cathode dividing equator. The equator acts as though it were a mirror. It reflects each extended unit of each pair in reverse. These divided pairs unite as two hemispheres of a sphere, which is also divided by an equator." [Atomic Suicide, page 280-281]
