Forgot to mention something about the last part of your post. I've found it very interesting that there does seem to be an "I" underlying discussions that relate to the spirit, soul, mind, heart, etc. I have to be focused on the study to best be picking it up. It could also be a rhetorical device.
Take our brain it is a blob of organic matter it is not alive it dosent think. It is the circuit bord if you will call it that. It is the electricity that fires between neurons that allows you body to function. It is the soul stearing the electricity. Like this. 1-2-1 left leg goes forward 1-3-1 right leg goes forward. Just to walk to the refrigerator and open a pop and take a drink requires billions of firings in just the right combination. That denotes a level of intelligence beyond human understanding existing right inside of every human being. Just the level of intelligence required to get a "stupid" person to walk into the restroom in time requires a higher intelligence than any human alive can function at. Its mind blowing haha.
