Our sense of time is a composite illusion cause by the interaction of several factors; (1) the movements of and the changes displayed by objects as they move and change in space, (2) our memory of the movements and changes that have occurred before the movements and changes happening now - this memory is the actual container of what we call the past, and (3) our imagining of the movements and changes that will occur behind the movements and changes happening now - this imagining is the actual container of what we call the future. Time is only metaphysically conceivable. It does not physically exist. It is easy to differentiate time from space because one can easily reach out and physically touch the here-ness and there-ness of space, but one cannot do the same for time except through the mediums of memory and imagination. Physically time is only an abstract of the mind extracted from the perception of the sequential movements and changes of concrete objects in space. An object's movements or changes that preceded the object's presently perceived movements or changes are retained as an abstract in memory and is called the past. An object's movements or changes that are anticipated to occur after the object's presently perceived movements or changes are abstracted from imagination and called the future. One cannot physically reach out and touch the here-ness and there-ness of time; one cannot physically reach out and touch either the past or the future except via a mind field, because it is only within an abstracting observing mind that a time field can be conceived. Once concieved it can be used as an existent by which to percieve alternate worlds whose present fit the time-traveled-to point at which one wishes to arrive. If time physically existed one would actually be able to move through it as easily as one moves through space from here (the present) to there (the past or future). One would be able to physically move from the now to the past or to the future, and vice versa. Astral Projectors, seemingly, can travel to the past or future at will, and therefore apparently contradict the assertion that there is no time. However, on closer examination - given what is known about the macroverse and its ability to create microverses based on any longings that we have for the fulfillment of desires for things in our memories or imaginings - astral projectors are able to experience time traveling illusions when they enter universes that present historical re-creations or imagined expectations. This movement of consciousness can easily give the illusion of time traveling and is similar to the linear illusion of moving through time that people physically experience. Sooner or later an astral projector discovers that he, or she, can enter different universes presenting different presents that may re-present something in his or her memory or expected future. But, this is not time traveling. It is still space traveling.
When the frame of reference is changed, the succession of time as it has been experienced in one frame is experienced via an altered succession in the new frame of reference. That is, the succession of time does not remain the same from frame to frame. If success is experienced by the forward movement of time in one frame, success is experienced by the reverse movement of time in its opposite frame. In a frame in which time moves in reverse, one cannot succeed by trying to enter the future from the present. Instead, one succeeds by entering the past as it is induced, induced via recollection, within the present and the effects of that induction observed within the present.
