“Seth material” search engine (Jane Roberts)

The great communication system within the body itself is dependent, then, upon the constant inner flux and flow of these units. On one level the body’s very survival is largely determined by the units’ propensities for selectivity and significance. Also, however, the body’s physical reality is a seeming constant in a seemingly constant physical existence.

At no time, as a rule, is your body not here to you. Your experience seems centered within it, with the rest of the world safely outside. However, the particular selectivity of your kind of consciousness rides over lapses that you do not recognize. In a manner of speaking, your bodies blink off and on like lights. Their reality fluctuates, from your standpoint. For that matter, so does the physical universe.³

You can understand what is meant by saying that your consciousness fluctuates — for each individual is aware of various intensities and concentrations. You are more alert, or, in your terms more conscious on some occasions than others. Now the same applies to these units of consciousness — and to atoms, molecules, electrons, and other such phenomena. The world literally blinks off and on. This reality of fluctuation in no way bothers your own feeling of consistency, however. The “holes (spelled) of nonexistence” are plugged up by the process of selectivity. This process chooses significances then, again, around which experience is built, and around which “life” is felt. The very sensations of one kind of life then automatically set up barriers against other such “world-schemes” (hyphen) that do not correlate with their own.

The one self that he recognizes is the only part of himself of which he is presently aware. Other facets of consciousness available to him, and a part of his greater nature, appear foreign, or “not-self,” or “beyond self,” because of the focus of selectivity as it now operates.
