What is past is non existent, like death as an abrupt end or even as what you were experiencing yesterday or five minutes ago has disappeared. It is irrevocable and unrecoverable, but gone completely and quite unreal. The moment you take experiencing as the fundamental reality this stares you in the face. Insofar as past occurrences have consequences affecting present and future these belong entirely to present and future, to their peculiarly constrained structure, the past does not inhere in them. Unlike the past they are not fixed, and much of future oriented intentionality is directed towards evading or confirming these constraints. This being-in-time is so fixed in experience as to be itself not subject to time. The complete and utter falling into non-existence of the past is the ever-present death which 'powers' experience. Any way out which is not a way out of time is no way out.
