It is commonly known that space has three dimensions identified as length, width, and height. But, when it comes to time, modern science has yet to discover its true nature. Now, let us think for a moment about our own experience of time.
From a subjective standpoint based on our own experience, time would seem to be much like a line or continuum. Webster defines a continuum as "...a continuous sequence in which adjacent elements are not perceptibly different from each other, although the extremes are quite distinct."
Although, when measured, the passage of time appears to be a constant (i.e., under normal circumstances, 24 hours will always be 1,440 minutes which will always be 86,400 seconds, etc...), our subjective experience of it is not. We often have the subjective experience of time moving faster or slower than it actually does. We even have expressions such as "time flies when you're having fun" or "a watched pot never boils," indicating that our experience of time is governed more by our state of being than through direct perception.
The Line of Time
Now, think for a moment about the nature of a line and try to imagine what it would be like to exist as a being that experienced life as a singularity or point along a line. You cannot look right, left, up, or down for those dimensions do not exist to you; only forward or backward along your line of experience.
Looking ahead, one would only see the point directly in front of oneself. Looking behind, one would only see the point directly behind oneself. Such a being would be incapable of seeing beyond his or her immediate place in the line and would not know the past or inclination of the future.

And yet, for us, this is not the case, for we possess the faculties of memory and foresight.
Concurrent Time
Thus, we can see that our experience of time is not limited to one dimension. we can recall past events and predict future ones. Therefore, upon contemplation, it must be seen that, at a minimum, our perception of time is not linear but two-dimensional that includes both an "x" and a "y" axis. This introduces the concept of concurrency, which is simply a way of saying that two or more events happen at the same time.

For example, As I write this, I'm sitting in my hotel room in Seattle and drinking a cup of coffee. People around me are engaged in several activities concurrent with my own process. If time were truly a linear phenomenon, I would have to wait my turn until others had finished their 'events' before I could engage in mine. Furthermore, I would have to finish my coffee before I began writing.
Note: The human complex, with its Five Centers, is designed to simultaneously process five frequencies of experience. Though due to our imbalances, this is rarely the case:
Its automatic associations as well as what it portends. (White)
Its physicality, as well as its style and nature of movement. (Red)
Its suitability for oneself or its possible dangerous aspects. (Blue)
Its emotional content and what it's connected to. (Yellow)
Its creational value or propositional aspects. (Green)
Third Force Blind
The Law of Three states that for any event to manifest in the universe, three distinct forces must be present; an active (+), a passive (-), and a neutralizing force (N). Yet, because of our lack of conscious development and refinement, we tend to be 'third force blind,' meaning that while it's often easy to see the active and passive principles involved, it is very difficult to see the neutral vector which exists in everything. Indeed this is the case with the third dimension or aspect of time: Eternity.
Eternity as defined in The Tradition, simply states that everything that has happened or will happen is both extant and enduring. This is a difficult concept to grasp. By way of example, consider the fact that one may look up at the heavens on a clear night and witness the event of a star that happened 100 million years ago. Because of the vast distances in the universe, it takes time for the light of a star to reach us.
And so it can be said from our perspective that the past events of a distant star are occurring at the time we witness it - even though elsewhere it may have happened 100 million years ago, for us, it's happening now.
Another example; it takes approximately 8 minutes for the light of our sun to reach us, which means that if our sun were to disappear suddenly, we would not know of it for 8 minutes. Not only would we not have any knowledge of it, but for those 8 minutes, it would not yet have happened.
Now, think for a moment about the profound ramifications of this notion. If you could travel alongside a particle of light (photon) that was emitted in the final breath of the sun's demise - the information it carries about the event would be an eternal phenomenon. Ever present. As it successively passed by the "now" of Mercury, then Venus, and Earth, it would carry this information on its eternal journey outward to the farthest reaches of the universe.
However, from your perspective as its light-speed traveling companion, the event of the sun's demise would always be "now." Time does not exist at all for a photon. So too, since light does not expend energy to achieve "movement," space does not exist for a photon either.
Light neither moves nor experiences the passage of time. It is simply the carrier of a bit of eternal information that coexists with all of the rest of the information in the universe. This is called eternity.
It is a bit more challenging to explain how the future is eternally present, but an attempt will be made.
Thinking again from the standpoint of a particle of light, one can imagine a scenario wherein a photon carries the information of the event of a star that exploded 6 billion years ago. Now, if you recall, for this photon - this information is always "now"; the information it carries is always "the present." Now imagine that it passes by the earth, which is 6 billion light years away (but remember there is no space and no time for a photon). If it had eyes, it would observe our planet as it is 6 billion years from its own "now." For the photon, this, of course, would be the observation of a "future" event (in our terms), but since there is no past or future for a photon, it simply would observe it also as "now." Thus eternity includes all 'past,' 'present,' and 'future' events simultaneously.
Note: The knowledge presented thus far is a great key to understanding the reciprocal nature of the Ray of Creation in that it explains how the universe can be likened to a perpetual motion machine wherein there is no effectual diminishment of the essence of The Absolute due to the passage of time.
And thus, it is time to conclude this writing with the intention that we will examine, refine and elevate the subject in another writing regarding the perception of time and levels of consciousness.
Many respects,
Pierce!
