I've been writing when I should be drawing, but the writing is becoming fascinating in an unexpected way: what is a soul?  In Christianity & associated beliefs, the soul is the spiritual, the impersonal piece of  being that returns to wherever it came from - Heaven or Hell.  It's the bit that reaps the rewards for actions over the lifetime, karma and not.  It's the part that doesn't belong to the individual but to the creator.  The creator's breath of life.  The spark of life, of divine life within the muddy clay of matter. 
In my PhD novel, A Fabulist's Alternity, there is a world where souls are different - they have existences that are apart from their physical counterparts (so far there is no mention of mind, though it's obvious the entities have one).  This autonomy goes as far as the soul being able to enter and remain with another being altogether, therefore consigning its previous physical counterpart to death - without a soul, the entity cannot survive.  But the soul can.  And does.  However, these souls, unlike the human idea of soul, is mortal.  It is probably very very long-lived, but nonetheless, can be killed, can die.  And does.  It has the powers of healing, of restoration, but not resurrection of the dead - as far as I'm aware.
I hadn't expected to encounter souls in this fashion.  Souls are generally accepted but really, they are part of religious belief - the spiritual side of being that we generally don't interact with, not in any meaningful way in the 'real' world.  It belongs to the realm of prayer.
I am encountering a different type of soul, one that apparently can and does interact with its physical environment.  It is the spiritual side, but something that is both more and less than that.  It is certainly the non-physical side of these beings, though their souls also have a physical presence.
It's intriguing.
Is it some 'divine' spark?  The 'divine' breath?  I don't get that sense from them, but I will have to wait and see what develops.  And what do the souls bring their entities (unable to move one they reach maturity) that the younglings (who range freely and have their souls within them) can't bring them?
I'm going to be writing more on this.
