Experience is “layered” or “doubled” since the experience of every object is also the experience of the subject who experiences that object and the subject is known non-dually in every act of cognition: one can say that the subject is like the cloth from which all the particular objects of experience are then cut out.
The extrinsic vision sees multiplicity whereas the intrinsic one sees unity: objects are always Many whereas the subject is always One.
Concentration is a technique for the attainment of self-knowledge and, a fortiori, realization of God, that functions by artificially conforming the extrinsic vision to the pattern of the intrinsic one. That is, the commonplace manifold differentiation of experience is collapsed into a single point which, in itself, as a unity, is a fractal, hologram, or participation of Oneness as such. The isomorphism between the artificially-induced concentration on an object of the extrinsic vision through voluntary effort and the inherent unity of the intrinsic one, recognized, can kindle self-knowledge.
But more directly, God has no parts and no spatial situation. For this reason, God is therefore nowhere and, by the same token, there is nowhere he is not. In this light, it can be seen that the difference between “the world,” of which we are a part, and God is not one of space but of mode of existence. God has no parts while the world is constituted of them, of which, again, we are one. “The world” is the same thing, perceived piecemeal, as God, experienced through full participation and communion of spirit. We can’t become part of God even though we are part of the world because God has no parts, howbeit we can become God through participation in his nature, which is to say, through theosis. That potentiality of the human person has been the message and injunction of saints and martyrs and theologians and prophets since the beginning:
Is it not written in your law, I said, Ye are gods?
Hi Max,
It sounds like you are describing the so-called, "Experience of Subject-Object Distinctions", which is this cookie--cutter process of bringing the young human being into the realm of relativity. Steiner describes it very well in this lecture in which he demonstrates the true meaning behind the Son of God - Son of Man dichotomy, which is infused throughout the four gospels.

We experience the transfer from being a Son of God to a Son of Man around three to four years of age. That is the necessary time to begin to experience the Earth's pattern of relative relationships. Sometimes this experience can occur quite dramatically, and wherein Light Itself becomes the active agent. The atmosphere begins to shimmer and glitter, and it is like a kind of magic wand is being waved in order to create a kind of flux. At least, that is how I remember it. Then, light wraps itself around objects that were previously conjoined. Subject-object distinctions. I remember a specific moment in which Intellect and Individuality came together. Is this the transition from Son of God to Son of Man status? I was just six years old when this happened. Thanks again, Max.
The Trinity is another perfect mind-transcending example of God's unity and multiplicity. Have you attended a Divine Liturgy? It is truly the revelation of the multiplicity and unity through ritual.
