The only "thing" (or process) precisely equal to the universe remains the universe itself. Every description, or model, or theory, or art-work, or map, or reality-tunnel, or gloss, et. remains somewhat smaller then the universe and hence includes less than the universe.
What is left in our sensory continuum when we are neither talking nor thinking remains non-symbolic, non-verbal, non-mathematical - ineffable, as the mystic say. One can speak poetically of that non-verbal mode of apprehension as Chaos, like Nietzsche, or the Void, like Buddha; but "Chaos" and "the Void" remain only the words and experience itself stubbornly remains non-verbal.
