冥

Denotes darkness, typically implying a state of obscurity or occlusion:

1. Sensory/Physical: Dark, gloomy, or dim; often describes an indistinct quality that obscures vision or understanding.

2. Cosmic/Spatial: The Underworld or the realm of the dead; refers to a profound, unreachable depth or a desolate void.

3. Psychological/Spiritual: A state of oblivion or being "clouded"; can refer to the intentional closing off of external stimuli to achieve internal depth.

• Adjective: Dark, obscure, profound.
• Noun: The Underworld, the void.
• Verb (Rare): To fade, to become obscure, or to be shrouded.

Contrast with 幽 (yōu): While both describe seclusion and darkness, 幽 tends toward the quiet, sequestered, or hidden, whereas 冥 leans toward the void, the desolate, and the metaphysical abyss.

Standard reading is míng. Tang-period records indicate variants meng and mèng; these should be treated as historical or dialectal artifacts rather than primary guides for translation.
