Scripture uses the term soul (nephesh in Hebrew, psyche in Greek) to speak of the autonomic (self-regulating) depths of bodily life. The soul is the life-force of a body. 

Soul is what runs your life when you’re not actively deciding or choosing to do so. Like the autopilot program of a plane, your soul takes over when the pilot, that’s your heart (or spirit), is just too tired, distracted, confused, or otherwise disinterested in governing life.
