SETH:

"Your present is the result of your own poised consciousness, choosing its perception and the nature of its life from a field that is at all predictable only because of the greater area of organization available to it."

SETH:

"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 "no-self," or "beyond self," because of the focus of selectivity as it now operates."

SETH:

"By means of the brain the functions of the soul and intellect are connected with the body. Through the characteristics of the brain, events that are of nonphysical origin become physically valid. There is a definite filtering and focusing effect at work, then. Practically speaking, you do indeed form the appearance that reality takes through your conscious beliefs. Those beliefs are used as screening and directing agents separating certain nonphysical probable events from others, and bringing them into three-dimensional actuality.
