 after pondering these things for most of my life, and pondering them in Greek, not in Hebrew, it's even more chaotic in Hebrew. You've got the nefesh, you've got the neshomi, you've got the ruach. Those are three words that have to do with breathing. In Greek, you just have two. You've got apneuma, which means wind or breath, and you've got psiche, which is related to a word for breathing, but came to mean breathing.
