This is the fate of the soul when it is handed over to the base energies of a person, for the concubine is the feminine, receptive part of consciousness, the tender inner life offered up to appetite. The men who will not hearken are the lower drives of the body, the mob of unbridled desire that seizes what is given and uses it through the whole dark span of ignorance. Night is that darkness, the long unconscious stretch in which the higher nature is misused by the lower.
When day begins to spring they release her, for the rising light of awareness ends the reign of the appetites, and the coming of inner dawn is the only thing that loosens their grip. The abused soul is let go at the exact moment consciousness begins to wake.
Concubine: the feminine, receptive soul, the tender inner life surrendered to appetite
Night: the long dark stretch of ignorance in which the lower nature misuses the higher
Day beginning to spring: the rising of inner light and awareness that ends the reign of the appetites
