Don't be hung up on 'spiritual'.
I'm attempting to better understand what you mean by that word, and
perhaps help you better understand as well in the process.Maybe I don't need to understand...
If an experience is “nutritious", who cares what it’s called or what it means etc?
Apparently, you do?
As for the experience, I suggested you read post 21 of this thread. I noted and corrected an error introduced by the pesky autocorrect on my tablet. In case you can't backtrack, here it is again..
The processes that brought about this world we live in are awe-inspiring to me and go so far beyond the capabilities of humankind and even what most of humankind can comprehend that such awe becomes “spiritual". Not because it involves magic or supernatural but simply because it is so far beyond present human capabilities.
What don't you understand about this?
