The unfolding 'now' that is no other now because of all the participating parts creating it. But one thing left out changes now and IS and THAT, because it didn't play its part...it didn't add to the collective now that one is, whereby THAT IS, and became isn't.
Is that saying something all things can adopt? More-so the Universe? But what happens when something is missing and the Universe knows it and everything else doesn't? Can the Universe make up for it, and in doing so, everything else is none the wiser?
The saying still stands...but then again, it doesn't.
Does that make sense?
