An Internet dictionary describes the adjective "spiritual" as meaning:
Let's give "spirit" a pass for the moment and pretend we all know what that means.related to your spirit instead of the physical worldreligious, or related to religious issues
But still, using the dictionary definition, where is the line between anyone's uhhhh spirit "instead of the physical world?"
Spiritual stuff is sort of invisible, I guess, and it's usually big ... bigger than a breadbox ... big, as in god-big.
It seems to be imbued with something benevolent, but you can never quite be sure when it might come around and bite you on the ass.
Separation from the physical world may be OK for a definition of "spiritual," but when you try applying that separation, when trying to say for sure what is and is not "spiritual," things seem to fall into disarray.
"Spiritual" has a presumptive truth (why else use the word?) and yet what, precisely, is presumed seems to live in a land of wubba-wubba.
Even dissecting the word "spiritual" can seem to be bad manners -- it's taken that seriously.
Taken seriously enough to use without a backward glance and a sometimes-oozing insistence and yet not seriously enough for anyone to know what they're talking about.
Or maybe it's just me.
