The body is a borrowed vessel, like a rental car. sure, the soul may not truly be sold (as I see has been implied), and by this I mean irredeemable, but in order for certain entities to enter your house, they must be given permission to do so by the owner/resident, and not in an implied consent sort of way.

i feel this is why people who get famous take their own lives. i think for a brief moment they regain control and off themselves to stop the cycle of kiving in ones body (the soul) without having control. the ultimate example of watching a movie.

just my thoughts.
