Right out of the starting gate, @Sunstone I rated your post as funny because it really did strike me as more than slightly ironic. Then again, almost everything does. *bursts into laughter*
Where to begin?
The key here is "come away from" and so is necessarily within the domain of critical analysis. This is where the normal conscious mind tries to compartmentalize the experience in neat terms that fit understanding. The simple fact is, having been through this numerous times, that the individual does not know what they have experienced but the conscious mind has to come up with something and more often than not, because the experience is so divorced from normal experiences they determine that it is from some kind of god.
In those terms, but in those terms only, there would be some truth to the assumption. But... and it's a rather large but, it is just an assumption the conscious mind superimposes on the experience.
Again, in those terms, for sure, but again, only in those limited terms. Reality, quite fortunately, isn't quite so binary. In larger terms, the conscious self has simply created a fantasy that papers over what they are grappling to understand in order to understand. It's akin to shooting oneself in the toe, really. I will admit, that due to the incredible nature of the experience, one cannot easily understand it and so the leap to some kind of deity is fairly common, natural and not unexpected. It's all part of the cognitive process. With luck, that process with not stop there however.
While this is true, presented in this way, one comes to understand that "the oneness of all things" is itself an illusion, a stepping stone, as it were to an even greater understanding. To understand a greater picture of reality, one does need to go through this phase. On that, I will agree.
Oh well, just smack me if my drool is getting on the carpet. I have broad shoulders.
I'm not at all sure what your post has to do with the OP, Paul.
