“Seth material” search engine (Jane Roberts)

This inwardness is so adaptive and self-generating, seeking all outlets and possibilities, that it not only in your case formed a physical universe, but found new ways, operating through the new physical universe, to construct an additional field or plane within and completely through, or on the other side of while yet within the physical universe; this being your dream world, which is made possible because of the physical mechanisms and involvements themselves.

The unified units, then stronger, began again the process of joining with other such units through attraction. Some such units closed their boundaries and therefore captured, so to speak, no other psychic inwardness, but were content at this stage; and they became self-contained, relatively changeless physical units.

These units however, while not adding any more matter to themselves and being self-contained, could and did become units that were used as building blocks by other units which continued, not yet completed. And here the self-completed building block units, while not expanding within themselves, still became part of more complicated gestalts.

There is a communication possible between your universe and the universe of negative matter, but it does not involve the physical self. You are, in your present, confined to our imaginary fruit, yet to some extent you can know it much more thoroughly than you do, and its three layers can be understood to a much greater degree.
