Many people who practice meditation begin to identify with the emptiness they see and feel as their "real self," misunderstanding that to be the Absolute, the witness because everything flows from this emptiness and emptiness, or space, pervades all experiences.
But the Void, the inner and outer spaces, are not the witness, are not the Absolute, because the Void itself is experienced and is an object of awareness.
The Absolute is entirely beyond experience, including that of the Void. It cannot be experienced itself. You can only be the witness as a position of sentience, but you can know nothing about it. You cannot feel yourself as a witness, for then it would be an experience of the witness. Anything, any knowledge is within phenomenality.
Now, some say phenomenality springs from noumenality, that it is a reflection of the Unborn aspect of your being. Some call the world the "created," meaning it popped out of the uncreated, noumenal, unmanifest, which they call the "real self."
But why would anyone want to call something unknown and unknowable as their real self? This Absolute, this unmanifest is entirely beyond knowing and experience, including the Void, so why label it and infer qualities and characteristics to it? It is merely the mind trying to grasp something entirely beyond its ken. Leave this philosophizing alone. It does not help in any way to talk about the relationship between the Absolute and phenomenality.
And remember, the Void, the spaciousness, is part of Consciousness and is not beyond it.
The only "reality" is what is presented in experience, including the world, your body, your senses, emotions, thoughts, etc. Even though it flows and changes continuously, it is the only thing we will ever know. We cannot know the Absolute.
Some say look at your experience and find out that which does not change, for that is your real nature. Of course that is the Void, the emptiness that pervades all inner and outer experience. Yet, it is still an aspect of experience, and is not beyond experience. Even this silence is not beyond experience.
Yet, you also are the Absolute. You begin to know this by intuition, then by a kind of inferential knowledge I call apprehension, and then it becomes a certainty once you realize that the Void is not the Absolute.
However, never forget that the you who really counts, is the manifest you, the human living in a world of form and actions. Do not deny this as being you in an attempt to run away from inner conflict, emotions, or the hurt and hate of the world. Embrace that human self.
