Maybe! I'm not sure. This seems like a pretty broad category of things.
Over the last 10 years or so, I've had perhaps three or four of what I'll call "spiritual episodes." (Brief background: I'm not in the least bit religious, in that I broadly reject all institutionalized definitions of God, explanations of Creation, etc. I suppose I'm more of a naturalist or "pantheist.") Anyway, these "spiritual episodes"... The only way I can think to describe them is this: They were times when I felt the enormity and complexity and..."amazingness"...of the universe so deeply that, for a few moments, all of my earthly concerns were washed away. I vividly remember the first time this happened, because it was so new to me: I was out for a walk in my neighborhood, and found myself looking up at the sky as I walked along. Not long into my walk, I spotted a squirrel running along a cable between two utility poles. For some reason, that set me off. I got to thinking, "How funny that our world has gotten to be so dependent on the intangible electrical impulses running through that cable, and yet, to that squirrel, the thing is no better than a particularly long and straight tree-branch."
Almost as soon as I had that thought, I felt this odd sort of release, as though I'd "gotten it," whatever that might mean. In the moments that followed, I remember thinking, "What if a car came around that corner ahead and just flattened me--killed me right now." Ordinarily, while a thought like that wouldn't inspire fear, it would at least seem bad or undesirable. What surprised me, at the time, was that the thought didn't seem bad. Rather, the thought just sort of rolled off my brain as insignificant and unimportant. Everything, for a moment, seemed to be part of one big equation, and my own part was so unimaginably minuscule that I couldn't be bothered to dwell long on it.
That lasted a very short while, and pretty soon I was back to thinking about family, stuff I wanted to do, work, etc. And that was fine, and I felt fine too.
I've had similar episodes since, some with less-obvious triggers. Some might look at these as sort of depressing, and certainly not uplifting. I'll admit that, in hindsight, it's easy to look at them that way. When they happened, though, they actually did feel uplifting in an odd sort of way. It was like being given a glimpse of Something Bigger. Perhaps, eventually, I'll have accumulated enough of these to connect the dots and put more of a shape to whatever it is.
Or not!
