Basic Knowledge, "Logic", "Systems Theory", "Physics" and "Quantum Physics", generally help to broaden our understanding.

There are many "Perspectives" of Reality, depending on our Level of Consciousness. All are verifiable within their limits and all are "false" when seen outside the particular system of perception. This is how the need for an Ultimate Truth emerges. The Way is Understanding. Reality is colored by the depth of our understanding. Only He Who is Fully Awakened, Fully Conscious, Sees Reality Directly, as It Is. This Direct View of Reality is the Supreme Experience of Existence, Truth, Life.

The Ultimate Reality Transcends but also "Contains" all Potentialities (all States of Consciousness, all manifestations of Consciousness). This is the "Phenomenon" of the Overlapping of Different States of Consciousness. It is a General Principle Applying Everywhere, (according to the Word of Hermes Trismegistus), both in the Invisible World and in the Physical World of the senses. We are talking about an "Overlapping" Relationship (the "States" are Overlapping, not "Dependent", nor "Parallel", nor "Alternating"). An example in the Natural World is Light (White Light) which contains all the Radiations (Colors) of the Light Spectrum.

When the Conscious "collapses" into a particular State, the Consciousness of the Field (Involving many levels of awareness) is "Projected" with the goal of Transcending the Specific Field of Consciousness. Thus, Consciousness Expands (Awareness Deepens) and there is a qualitative elevation of the Conscious.

Transcendence is actually a reverse process of the "collapse" process. In philosophical-psychological terms we speak of Focus-Absorption of Consciousness ("collapse") and Detachment-Dissolution of Consciousness (Transcendence).

All these follow Objective Laws and are not products of chance. There is Class in Creation.

From the Viewpoint of Awakened Perception Reality is One (the one we described before, of “Overlapping”).

From the point of view of a "Formed Perception" there are Discrete States.

Transition to the State of One Reality is possible by “dissolving” all “formed perceptions”.

Another description:

There is Only One Consciousness which is the Absolute Background of every organizational structure of Consciousness.

Consciousness Is Without Attributes, Space, Time. We call it Basic Consciousness. Upon This Basic Consciousness All States of Consciousness Are Organized. We call them Functional Organizational Structures.

A Consciousness, or Functional Organizational Structure, appears as autonomous and separate. It is a personal view of Reality.

So, how does it connect to Core Consciousness and how do we emerge from limited consciousness to Core Consciousness?

Basic Consciousness exists objectively, it is a given, It Only Exists. The Organizational Structure is nothing more than a "construction". Therefore, there are no two realities. There are not two Selves (Higher and lower). It needs no development, or realization. The "organizational structure" that functions as a distorting mirror of reality simply needs to be dissolved.

Try to understand, on an empirical level, the difference between Direct Perception and conceptual thinking. Direct Perception is the spontaneous, uninhibited and "interference-free" grasp of what is happening (without "process"). It is something that happens objectively. Conceptual thinking has a more "subjective" character, it is our own "construction" and a "personal" perception of reality. We "do" it.

On a philosophical level, where they have analyzed Perception, as Direct Action (and Direct Viewing of Reality) and as a "process" in which we "participate" and more or less "guide", it is in Buddhism. It is worth studying and understanding the difference between Prajna and vijnana . Both terms refer to “knowledge” which is expressed by the root – jna. The preposition Pra - in Prajna means the immediate, the source, the basic that becomes itself and thus Prajna, means the Basis of Perception, the Original Perception in which no "interference" has been made. The preposition vi - in vijnana means “distinguishing” the subject from the object (the dual perception) and refers to limited perception and logical conceptual thought. Prajna, as the Base Perception supports vijnana (at any level), which is nothing but a “Formulation” of the Base Objective Perception. Thus, Prajna not only “precedes” vijnana but also “remains”, like Objective Perception, when every vijnana has been “dissolved”. Watch this.

Moving into an Expanded State of Consciousness (Deeper Awareness) is accompanied by some observable "phenomena" that manifest the Expanded Consciousness or altered Perception of Reality.

1) First of all, there is a sense of freedom, liberation from the limited space of previous perception. We perceive freely, without the conditions and limitations imposed by our "constructed" perception.

2) There is an "alteration" in the sense of Space. The Space becomes "Open" and includes "everything", without the previous limited "classification".

3) The sense of Time changes. There is a sense of independence from specific historical time, a Scent of Eternity.

4) As the psychological center of the previous state of consciousness dissolves a sense of "non-self" emerges, a new state of "non-dual consciousness".

5) As the new consciousness behaves independently (but not "disconnected") from the body a sense of "timelessness", immortality is spontaneously "born". The death of the body ceases to matter because the center of sense of existence has shifted from the body to the inner sense of existence.

6) There are other phenomena that are observed but one can ascertain them himself, moving to this new consciousness.

7) The "Transition" is not the Final Transition but one of the Ever-Expanding States, an "Opening" to Expansion into Open Infinity, to Final Liberation in the Ultimate State.

Note that we are always talking about States of Consciousness (or Perception) that only limited consciousness perceives as real and total states of existence.
