We dont just possess a consciousness, We Are Consciousness Itself. Every "thing" is made of Consciousness, including of course, our brain and body. When Consciousness observes any modification of its own inherent radiance, it creates a "brain fart" and makes scientific experiments go wonky.
When you Realize the Enlightened State, you are resonating at the speed of light. You Realize you are not a mortal body-mind, rather you Are Consciousness Itself, but not as an ego personality who says to itself, "I am consciousness" There is no duality left. Only Consciousness Itself, blissfully and eternally enjoying its own Play and Self-Radiance. Consciousness is not a creator, yet all manifestation occurs within Consciousness Itself. Consciousness is Acausal, Self-Existing prior to cause and effect, prior to time and space, yet includes time and space. And dont forget, Im not talking about an abstract "thing" Im talking about the royal "we", our True Self nature. We Are truly One on the most intimate level possible, to the degree of it being absolutely impossible for there to be any kind of separation In Reality, there are only modifications of the Light of Consciousness.
