Therianthropy as seen by a loaf : Souls have shapes
Reincarnation! Souls! All those fun things.
I believe that there are a finite number of souls, but that they're just recycled over time. However, They're not just randomly tossed, they're put in the same if not the next best body *most of the time*.
The soul matches the shape of the body, as species evolve slowly over generations, the soul slowly changes with the body. The more interesting experiences come from misplaced souls, for me, that's a soul in the shape of a coyote. It's why i experience things like phantom limbs, echos of this original shape.
Why was my soul 'misplaced'? I'm not sure. Maybe there's some reason for me to experience life as a human, maybe there just wasn't a coyote or similar body available, but that's not much of my concern right now.
I'm here, I'm human (at least physically), and that's okay.
