Sanming TonghuiVol. 1, On the Nature and Fortune of the Sixty Jiazi (verdicts & remarks)
Ding You Fire is the spiritual resonance of ghosts and deities, formless Fire; it delights in Chen, Xu, Chou, and Wei. Heavenly Officer, Joyful Spirit, Flat Head, Broken Character, Deaf and Mute, Great Defeat.
In Yi Mao, Gui Si, Ding You, and Yi Hai, though Water and Fire are dead and extinct, they remain pure, luminous, and wondrously fine.
When Fire dies and reaches extinction, it shines bright within while shadowed without, reflecting its light back inward; when Water dies and reaches extinction, it becomes profoundly limpid and clear, bright enough to mirror one's beard and brows; hence they are pure, luminous, and wondrously fine.
