No. You are adding too much to it. Being in union with God is simply being who and what you are right at this moment, without any idea (or implication) of God. The moment there is "implication", there is otherness, and God cannot be an object. Within the realm of divine union, There is no thought of either "God or not-God". In other words, God is just the ordinary state of affairs. It is Nothing Special; no calling attention to itself.
If that's the case, then why use the term "God" to describe this at all? What reason do you have to use it?
Belief is always based on rational thought.
It is? :sarcastic
That is the problem. The nature of God is non-rational (though not irrational). Belief in God is always about having an idea of God, and that is not God. The rational, thinking mind cannot grasp the Infinite. Therefore, all rational thought, all belief, all idea, concept, conjecture, notion, etc. must be dropped. There must be complete and total surrender of the "I" before one can begin to see. Divine union is not about belief; it is about seeing.
Hmm. It seems to me that you're talking about knowledge, but while taking away any tool we have to obtain knowledge. To me, this is contradictory.
History and religion are both about the past, one being a study of the traces of past events, and the other about the traces of the spiritual experience. But neither is about what is occurring right at this moment, and what is occurring right at this moment is what determines the course of history and religion. This is in sharp contrast to what we have been indoctrinated to believe: that the past creates the present. The wake of a ship does not create the ship; it is the ship that is on the cutting edge which creates the wake. History and religion are about the study of artifacts. The spiritual experience occurs outside of time, and therefore, outside of history and religion.
I take it you're not a fan of history, then. That's fine - different strokes for different folks. I do disagree with your idea that "spirituality" is distinct from religion, though.
Part of the answer is that they are approaching the question from the point of view of conceptual thought coupled with a strong identification with the self.
And what's wrong with either of these things?
When did they ever embark on the path of proof at all? The thought of proof or no-proof never entered their minds.
Right - there's no point "embarking on a path" for something that's readily at hand.
You're trying to make a false equivocation here, and I'm not buying it. There's a big difference between accepting something because the evidence is so overwhelming that you never bother to question it and accepting something simply because you never bother to question the complete and utter lack of evidence for it.
Divine union is like a fish being born into the sea. His being in the sea and the sea being inside him is just his ordinary state of existence. He does not know of the sea because it is not an object for him; he was born into it so he is unaware of it. And so it is with man. Man is always in union with the divine, but he does not realize it, and so he formulates beliefs and opinions about the divine as if it were something Special and separate from him. So he embarks on a path of seeking in order to unite with something that he already is in union with. Because of this fallacy of separation, Buddhists say: "That which you are seeking is what is causing you to seek".
Fine; so we're "immersed in water". This doesn't imply we can't measure the water.
The existence of air can be determined via of instrumentation that are extensions of man's sense apparatus.
So can invisible TV signals which are not readily apparent as existent.
But the divine essence cannot be tested via of any such means, either directly by any of the five senses, nor by any scientific instrumentation to date.
IOW, all your fancy analogies about being immersed in evidence weren't really correct, were they?
All of these methods are based on rational thought. The spiritual experience is beyond the senses, beyond reason, beyond time and space, and yet, it is as close as your very next breath.
Great - then it's beyond knowledge as well. Any concept of God, including the one you've described here, can be rejected as being totally without foundation.
After all, if you can know about a thing enough to talk about it at all, then it's not "beyond the senses" or "beyond reason".
In fact, it IS your very next breath, but you do not realize it because that is not where your seeking mind thinks it can find it. In fact, science has eviscerated the Greek idea of breath as spirit, which they referred to as pneuma, via analytical methodology. Today, moderns see breath only as a function of biology and air only as a gas.
In contrast with the ancient Greeks, "moderns" also don't see earth, air, fire and water as elements. Guess what? The ancient Greeks were wrong and the "moderns" are right.
What I am getting at is that ancient man actually had a better immediate connection with the divine essence because he experienced things directly, rather than through the filters of acquired knowledge.
That's a foolish statement. "Ancient man" had just as much acquired knowledge as we do; it's just that their acquired knowledge was more often of poor quality.
