Metaphysics is the presumption that there is an absolute frame of reference for experience without any presumption as to what the 'space' of all possible experiences may be. As such it is irrelevant since if there were such a frame it would have no effect upon the experiences that were enabled by it. Worse than that however is that the idea of such a frame gives rise to a distortion of the ideas that can locally order experience from within. Apply this to the notion of existence as it arises in relation to whatever it is that distinguishes the immediate presence of the now, that which differs from all possible qualities. You are tempted to ask whether this sense of existence penetrates all the way through experience to being, but the question is asked as if you already know what is being. This question ought to be directed at, or oriented to, the mysterious 'already know' and not at the 'being'.
