Now we're there Nick.
There is no word or thought for what you are trying suggest is deeper than the "mystery of existence" because you're talking about that which can not be spoken at all.
Now because it can not be spoken, and there is no word (logos) for it, the term "mystery" is used because it signifies something outside of the range of thought and speech (ego) - something that thought and speech can't get at directly.
You are talking about the very thing that Campbell is talking about when he says "mystery" (mysterium tremendum).
The best things can't be spoken, because they transcend all speech.
The second best things are usually misunderstood because they are simply 'metaphors' that point past themselves to that which can not be spoken.
This "unspoken" which can only be referred to indirectly, by way of metaphor (words) is the ground of all being and non-being (duality). This is what the Gods of mythology are metaphorically representing across the board: "Is he or is he not, neither is nor is not"
The images, thoughts, and words of time and space are metaphorical for the ground of their own existence which is more fundamental than what we can get at.
Now we're there.
We're at the border of what can be addressed with language and what can not.
The realization is that everything that exists IS this unspoken factor that we've both been referring to the entire time. This unspoken factor is the ground of "all existence", and therefore is not separate from existence, or apart from existence, or opposed to existence. The great "mystery" is present in all of the forms and images of time and space which point right back to it.
The vital energies of the universe, the sun, the moon, the stars, the natural elements, the whole world, are radiant of this "unspoken" factor which can only be referred to with thoughts and words as a complete "mystery".
That's what I am, that's what you are Nick, that's what everyone IS.
This is NOT in opposition to astrotheology!
The astotheology is a way of speaking about the "unspoken" ground of all existence. Everything in mythology points to this realization and astrotheology is the second function of a traditinal mythology and therefore any religion that has evolved out of traditional mythologies, it can not be down played or removed.
The observation of the world and the heavens abroad is observation of the underlying "unspoken" factor that you're trying to point toward. Everything that can be called either subjective or objective (dual) points directly to the "unspoken".
Focusing on the subjective can serve the purpose of getting down to the inward "unspoken", but once there, once it has been discovered, when you turn around and move back toward the objective world of your senses you can see the radiance of the inward "unspoken" as being present in all of the objective forms and images of time and space.
"I and my Father (unspoken) are one"
(beginning and end)
(ground of being)
Metaphors, Metaphors, Metaphors...
