You will remember from previous posts or from reading the Seth material yourself, that a nonphysical, hidden reality preceded physical reality. Every possibility or probability that could ever exist was thought of all at once by All That Is and became “Divine Fact” in a different framework–one that is completely mental, not physical.
Before anything that is part of our physical world becomes physical, Seth says, it passes through various stages. The most important thing to know about these stages is that what propels them into being is consciousness. Everything is made up of consciousness.
Consciousness is the agent that directs the transformation of energy into form and of form into energy. (Dreams, ‘Evolution,’ and Value Fulfillment, Volume 1, Amber-Allen, 1986/1997, p. 137)
Seth describes consciousness units or CUs as the “building blocks” of matter. Fifty years ago we were all taught that the atom was the smallest building block of matter. Today, most physicists think of some yet undiscovered sub-atomic particle as the smallest building block of matter. Seth claims that ultimately humanity will realize that consciousness units are what they have been searching for. You can read a bit here about the physicists who have already come around to this idea: http://www.collective-evolution.com/2014/11/11/consciousness-creates-reality-physicists-admit-the-universe-is-immaterial-mental-spiritual/
Seth says that CUs act as both particle and wave at different times. When CUs act like particles, they experience their reality from the center of those forms, they focus on unique specifications, and they become individual. When they act like waves they do not set up boundaries for themselves and they can be in more than one place at a time. Think of a vast ocean in relation to a drop of ocean water to get an impression of this concept. And Seth says that CUs act as both particle and wave (or matter and force) all the time. So literally everything in our reality, even space, is made up of consciousness and results from consciousness.
Metaphysically, they [CUs] can be thought of as the point at which All That Is acts to form [your] world–the immediate contact of a never-ending creative inspiration, coming into mental focus . . . the CUs represent the spectacular foundations of the world in value fulfillment, for each unit of consciousness is related to each other, a part of the other, each participating in the entire gestalt of mortal experience. (Dreams, ‘Evolution,’ and Value Fulfillment, Volume 1, p. 170)
This word, “gestalt” is one that Seth uses frequently. A gestalt is a unified whole that is greater than the sum of its parts. Seth says that CUs all have a propensity for exploring possibilities and they form into units of all sizes based on the qualities that are significant to them.
Certain units would settle upon various kinds of organization, find these significant, then build upon them and attract others of the same nature. So were various systems of reality formed. The particular kind of significance settled upon would act both as a directive for experience and as a method of erecting effective boundaries . . . The units can and do intermix, yet because of the propensity for selectivity and significance, whole groups of them will ‘repel’ other whole groups, thus providing a protective inner system of interaction.
