To talk about anything, we need a context, or a frame of reference. Where you are is always relative to some other place, When is it, is relative to some other period in time. Tomorrow is relative to Today. Far is relative to Near.
The World we experience is a projection on a beautiful fabric made up of crisscrossing threads of time and space. These magical threads form the framework, the matrix, or the canvas on which are laid all the events of the drama of life.
While space is a perceptual dimension, time provides the temporal aspect. At any point in time, one seems to have access to a series of events in space, stacked one over the other in time slices of the past. We refer to this as memory.
One can access the childhood slice. days of school. or any other event in the past. there is a distinct boundary as to when these events occurred.And each time these are accessed they always appear in that exact order,and always the same events at same points in time. If we recollect the first time ever of going to school, we always recollect the same school irrespective of how many times or when we recollect. Also the order in which events have occurred seems to always be the same. This apparent persistence or permanence of the past gives credential to a reality of the past. A random recollection will appear a lot less real. The brain as a device that seems to capture the temporal stories is a fabrication for further authenticity. If all the pieces of information are in fact stored in the brain, who is it that accesses it?
Similarly one encounters space. It seems to be really fixed. we know where we are. We do know where other places are. The distances between places seem to be absolute. Both objectively as well as subjectively the spatial relationship of things and places don't seem to change. This continuity or persistence gives credibility to the reality of space and things in it. The distances between our home and the stores, distances between our city and others are absolutely fixed.They measure the same exact length.
A deeper examination of time shows that, only the moment or the Present is actually experience able. Past is only accessed through thoughts from memory. Similarly the place we are at now is the only place we can experience.Even the next room is only accessible in our thought. When we do move to the next room, then we may be experiencing it at that Present moment, and the experience of the previous room becomes a thought in the past.
Similarly a deeper study of materials show how immaterial they really are. From a physical as well as temporal point of view matter as we experience it is not as real as well think.
A clear understanding of how such a Matter without reality is placed in the matrix of Time and Space which are as much a fiction themselves, is a striking revelation that results in the true Knowledge of Who we are. If Time, Space and Matter are not real, then the one asking about it, talking about it and having an apparent experience is the only real Self. Knowing that I am that only Self is Knowledge.
Obtaining and staying in this Knowledge, one is able to experience life as a mere play of light and sound in the apparent matrix of Time and Space.
