The sons of Belial besieging the house are the base, worthless impulses of the lower nature swarming the body and beating at its openings the moment the person relaxes into ease. The house is the body, its master is the ruling mind, and the guest is a higher visitor taken in for shelter. These clamoring appetites demand that the elevated element be handed down to them, dragged into their level and used up in the flesh.
Belial means without worth or without yoke, the ungoverned craving that acknowledges no rule. Merry and off guard, the inner house is surrounded by these unyoked drives pounding to seize whatever rises above them.
City: the settled mass of habits and thoughts a person builds up around the self
House: the body, the dwelling in which the ruling mind and its guests reside
Sons of Belial: the worthless, unyoked cravings of the lower nature that acknowledge no rule
Door: the opening of the body through which the lower drives press to reach what is within
