I’ve noticed some people using “spiritual” to describe notions they consider aesthetically sublime and morally uplifting but not well understood, when they are not particularly motivated to understand them, without any commitment to their being supernatural. This may be what you refer to in your second meaning, I’m not sure.
There is, of course, a lot of potential overlap here with supernatural notions.

Yes, that’s roughly what I was referring to.
