You can not die.
Simular to a computer turning it of all work stored in ram, gone.
If someone start it again it will get going, rom will guide it along ist's path
The soul is mere occupying the body, flesh bones at this particular point in time, it does not die.
Selling the soul inhibits the reincarnation, rebirth, there is nothing worse as a soul without a body.

Body is vessel for soul and any other clean or unclean spirits you invite through your words,thoughts and deeds . Only the flesh dies
