In Islamic cosmology and other spiritual systems, the nadir is one of the six directions, often symbolizing the lowest spiritual state or the depths of the material world. In poetry, it represents the 'dark night of the soul,' a period of profound spiritual desolation, doubt, or suffering. This state is not merely negative; it is often a necessary stage of purification and humility on the path to enlightenment. Poets use the nadir to explore themes of abandonment, existential crisis, and the search for hope in utter darkness.

Nadir, the spiritual “lowest point,” appears in the Psalms (“out of the depths I cry”), in Job’s despair, or in the Dark Night of the Soul; it is not mere depression but a crucible of purification; poets use nadir moments to explore abandonment, doubt, and the paradox that divine absence may be the prelude to deeper presence.
