In my opinion, properties of the soul are:
-Tied to the consciousness, but seperate from the consciousness
-Affected by the choices the consciousness makes, nothing else (every religion I know of has this idea when it comes to souls)
-Has no physical presence in the world, unless it has been seperated from the consciousness by death (angels, ghosts, spirits, etc.)
I'm very tired so I'm probably leaving stuff out... I'll add more criteria if needed.
