If you imagine a single complete moment of your waking experience occurring out of a durationless void empty of emptiness there is nothing to distinguish it from that same moment within the flow of ordinary waking mind. Whether it is preceded or followed by other such moments in a sequence has no bearing on the moment itself. It is a sort of Markov property of experience as self-understood that it needs no connection to other moments - or you could say that its nature is to have always already been 'Markov-ised', that is, that to be what it is it must already contain every retention and protention that defines it. This thought experiment shows that experience and consciousness are two different things - or that the greater part of what it is to be conscious is not experienced.
