Time is a construct of the mind as shown by Albert Einstein in his special theory of relativity. The fact that even the most "sophisticated" minds of our age have yet to grasp this fact, is suggestive of how conditioned we have become by certain persistent but erroneous assumptions of "reality."
Einstein realized that the speed of light is absolute, the same for all observors, whatever their speed. Space and time are not a constant but vary with the speed of the observor. So Einstein realized something called the space-time continuum, out of which both space and time appear. This continuum is neither space nor time; it is the noumenon, something we don't know or describe. All we know is the space and time it gives rise to.
What Einstein also showed is something called the "interval," which is the subtraction of the square of space and time, or the square root of time, and this turns out to be a constant. The distance in space-time never changes, although what we experience as time changes. So, this leads to more discoveries about light.
What happens if you actually travel at 100% of the speed of light? Light experiences itself as traveling NO distance in NO time. From light's point of view, light does not actually exist in space and time. The birth and death of a photon are the same moment. There is no "locality" for light. From light's point of view of the space-time interval, light does not have a speed (186 kmps). So the "C" of E=MC2 is actually a constant ratio of the manifestation of space and time (think about this very carefuly).
So, however real time may appear to our restricted sense of objective self in space, it cannot and must not be an absolute reality, but an effect of our perception. Some may say that we can never know the point of view of light because we can never actually travel at light speed by any known technology. Yet, this way of thinking may be the result of that same persistent, but erroneous assumption of "reality" that has attenuated many of the most brilliant mind of our age (even those working at NASA).
"Light" appears to be an apt metaphor for the state of "pure consciousness" as described by many explorers of consciousness. Those who have experienced "pure consciousness" through zen and meditation have an overwhelming sense of being "light" or "enlightened" which transcends any sense of time and space. If you want to get a flavor of what this experience may be like, ask astronauts like Edgar Mitchell, Rusty Schweikart, and others who've been outside of earth's gravity, experiencing the cosmos from a pespective of oneness and interconnectedness.
