You are the eternal consciousness that is the source of all consciousness, experiencing life though the filter, the lens, of the experiences you are exposed to in this temporary experience, this mental construction, where you have forgotten that you are the very force animating the world around you, the characters you interact with, and the experiences you have. I am you experiencing life through my eyes; you are me experiencing life through your eyes. Together we explore this holographic, meditative, mental universe exiting only within the one consciousness that is within all consciousness.
Every decision that has ever been made, is a split between new realities, both timelines continue on their path with more choices along the way, it is like an endless tree with endless branches. We experience reality like a drop of water that follows the path from the soil through the roots and the trunk, and on into a branch until the very tip. One drop can only take one path, what we identify as the self, the sense of "me", is the drop of water. But what we truly are is the consciousness that holds all the "water". We are that tree that contains all the paths, we are the water that takes the paths, and we have forgotten we our both. You cannot change the path your life is going to take because you have already made all of the choices, but you can control how it makes you feel, and learn the lessons you wished to learn when you made your decision to experience being a drop of water on a specific path and forget you are the tree.
The physical universe is an illusion, a mental construct, created within the mind of "The All". We are all the characters in this dream we call universe, constructed and animated by the mind of "The All", intentionally forgetting our true nature, to test our consciousness of our own immortality. I am all that I see, you are all that you see. I am you, you are me, and we are one. Separation is an illusion, the absolute truth, is there is only one of us here; the relative truth is that there are many individuated points of consciousness. There is no need to fear death, or anything else, because you are not your body, and therefore no real harm can ever come to you.
