What if each cell in your body has a soul? Is "your" soul a composite of all the little ones, or something supported by the little ones, or separate from the little ones?
What if we all are connected back to one soul? What if every incarnate living entity is a door to the one soul we all share? What if personality and mind are small valves that leak just enough soul so that it looks like there are lots of us, but actually there's only one?
