"We will carry the example of the electric tube still further. Consider that tube as a miniature replica of the COSMIC VACUUM ZERO of the Creator's Mind. Now consider it as YOUR Mind. Now follow that up by realizing that there is no light in the tube, because you are not recording your thought-images in them." [Atomic Suicide, page 158]
