Some Thoughts

Many traditions present the idea of reality as interpenetrating levels. Certainly we are aware of interpenetrating levels within us such as cells, molecules, electrons etc.
It is not as easy to conceptualize (and perceive) levels above us, but it can be done.
What science calls the quantum vacuum is a dim perception of a higher (deeper) level of reality. And that level of reality follows different rules than the levels we are used to.
The reason for that is that this higher level (astral level) has a greater degree of freedom. For example it is not constrained by time and space.
In this post I wish to focus on one very small (but important) aspect of this issue. The subject is time.
We often say that a higher level ("God" if you prefer) is beyond time and space.
It would be more accurate to say that "God" is beyond our time and space.
It ("He") still has its own time and space.
For example let us say that the sun is a higher level of being.
The sun level is beyond our time. All of human history is but a moment in the time (life) of the sun.
The sun experiences (sees) all of human history together.
As an analogy, imagine a DVD playing infinitely quickly so that all of history recorded on it (in full 3d) would take a fraction of a second. If you had the capability to take it all in, then you would be approximating to the level of the intelligence of the sun.
The word for this is "eternal". The word eternal is often thought of as an infinite extension in time. This is not the sense in which I am speaking. In the sense in which I am speaking, it is continuously present.
So in our analogy with the DVD, you as the watcher of the DVD are constantly present across all of the time of the DVD. Whenever someone on the DVD would look "up", you would be there unchanged. The rate of time is different between the two levels.
Science is dimly aware of this idea in the Theory of Relativity and in the unique nature of light which is beyond time.
As Bernhard Haisch put it:
"..let us ask ourselves how the universe of space and time would appear from the perspective of a beam of light. The laws of relativity are clear on this point. If you could ride a beam of light as an observer, all of space would shrink to a point, and all of time would collapse to an instant. In the reference frame of light, there is no space and time."
As Rodney Collin put it:
"If light can diffuse and endure undiminished for half-a-billion years, it can surely do so for ever. This means that all light, from a candle or from a super-sun, sooner or later fills the entire universe. Light is undiminishable, eternal and omnipresent. In every religion that existed these qualities have been recognized as divine. So that we are forced to the conclusion that light - actual sensible light - is indeed the direct vehicle of divinity: it is the consciousness of God."

In summary, "God" is eternal in relation to our time.
