Eh? Again you are just making stuff up.
Buddhism teaches dependent arising and conditionality, not absolutes like "Brahman" or "God" or "Cosmic Consciousness" or "Ultimate Reality". The notion that sunyata is equivalent to Brahman is ludicrous, and merely demonstrates your ignorance of both Buddhism and Hinduism. You continually misrepresent teachings from both traditions in a desperate attempt to pursue your shallow syncretic agenda.
The point of the Visuddhimagga verse was to underline that in Buddhism there is no God to be found, and no mystical "reality" behind or beneath phenomena. Only phenomena. As the Visuddhimagga verse clearly states it: "Phenomena alone flow on.." And of course this is just another way of talking about sunyata, emptiness.
Note that I say "sunyata", not "Sunyata" because it is NOT an absolute, that was the point of Runewolfs quote about emptiness of emptiness. Clearly you don't understand this pivotal point.
This is never going to fit your syncretic agenda, get over it. Stick with your idiosyncratic idea of "spirituality", which looks like a sort of pseudo-Hinduism. You seem to be suffering from the "There must be more than this" syndrome, continually clutching at metaphysical straws.
