Reality, like god or actuality, is something that cannot be understood or explained. We can know about but what we know is not the actual thing. There is always more we don’t know.
Beyond what we know (knowledge) and what we don’t know is a witness or conscious, an un-knowing and deeper sense. Our actuality, of self and experience as projection, is already beyond what we can determine (including what we know and don’t). With deeper sense of knowing and unknowing we may join the process of reality in relation with the whole body alive in creation, in and of reality.
We may know and understand that we are a projected actuality, and as such may relate with the whole self, whole being, and whole body in reality, because we are his or her projected part.
