That Dweller at the Threshold is your Holy Guardian Demon.
My view is that:
- The HGA is the entity that operates the Christian soul body (Neshama, higher mental body:5.3 to 5.1) until after first stage enlightenment when it progressively withdraws
- The Dweller on the Threshold is the defensive entity on 5.4 (top of personality mind) that operates the defense systems for the human. The Dweller's highest asset is its self-esteem. It hates to be wrong. When the human learns to control its lower mind, the Dweller moves from defense to creativity. Thus the "demon" appears to change to an "angel"
