Or is it that we are spirit's who are the lord's of our bodies, and every little chemical and electric reaction in our brain is like our own universe, and our consciousness is like a god of that little world?
Eh, I can't make 1 hair of my head change color naturally. I can move my body, exercise it, build up muscle if I wanted to. More or less the same w my mind. I can even shut my eyes if I want to. But I can't turn off my hearing. If I'm in pain, I can't turn that off either - physically, mentally, emotionally, spiritually... well, not without some chemical additives anyway, which I eventually had to forswear. So "Lord of my own body" seems a bit of an overreach. No one else has direct use of my appendages, so far as I can tell, that's good, but that's about it.
Even
that can be an overreach (I know we both quit smoking recently, but how many times did you swear off previously, only to suddenly find you had auto-grabbed a pack and lit one up without remembering the swear-off? Quite a few for me)
I'm not entirely certain where my thoughts come from - I suspect "from the heart/soul" which can be a bit disconcerting depending on their quality and content from time to time.
"our brain is like our own universe, and our consciousness is like a god of that little world?"
Kind of, but small god, small world.
Imagination is limitless, but locked in that world, pretty impotent.
It's also limitless... but in a finite direction, so to speak. And not necessarily the best one.
And eventually things go bad there, like Lewis's "spoiled egg" that never hatched
I don't think we are meant to be Gods there either
(and believe me, I tried - it didn't go well)
(but it's OK, almost no one noticed lol)
Or perhaps we're all interconnected pieces of a larger human spirit.
I think we may be (having been created by a divine spirit) pieces of that divine spirit
So not seeking the will of that Creator and then doing it
(or knowing it, and then refusing and doing the opposite...)
...It's a little like a piece of God turning it's back on itself
Which sounds like it would be a pretty painful contortion
And I can assure you
It is
