Perceiving all in the now is impossible. That does not stop us from trying. Nor does it prevent understanding the all in the now.
Just as a rodent can understand that more dangerous worlds exist beyond its own, so to may we grasp that same truth. The rodents and us will never see or touch the rest of reality in all our existence, yet both can know existence is there.Not seeing what we know is more detrimental to us than to rodents. Rodents are, like us, born with oneness however they do not lose it in their societies as we do. This in-born oneness all things have destroys the need to validate the reasonlessly known.
Much of our pull toward the understanding of the ways of God ironically cut us from the cord of oneness with God. Like telling an engineer to stop explaining things while we use Lincoln logs to figure out what he's trying to explain. Our over active brains have defeated us.
It is not all for lost though. For we at any time may set the logs aside and listen to the engineer. All it takes is quiet.
