The bottomless pit is the base of the spine and the lower nature coiled there, the depthless reservoir of raw desire in a person. When it is opened without control, the fire in it does not rise as light but pours upward as smoke, and the smoke is confused thought, the fumes of passion clouding the whole inner sky. The sun is the illumined mind and the air is the breath and clear reason, and both go dark when the lower furnace vents unchecked into the head.
This is an inward eclipse. The same serpent-fire that could give vision instead blackens it, because it was released from below in disorder. A person in this state cannot see; the light of the mind is smothered by the smoke of an ungoverned lower self.
The bottomless pit: the base of the spine and the lower desire nature, a depthless well of raw craving in the body
The smoke of a great furnace: passion turned to fumes, confused clouding thought rising from an ungoverned lower fire
The sun: the illumined higher mind that gives inner sight
The air: the breath and clear reason, the atmosphere of the mind
