不言而信，不動而威，不施而仁，志也。
Mourning, when not embodied in hempen garb, consists of sorrow.
鍾鼓之聲，怒而擊之則武，憂而擊之則悲，喜而擊之則樂。
Music, when not embodied in sound, consists of joy.
The thing that inspires belief without speech, that inspires awe without action, and that inspires human empathy without acts of charity is the will.
其志變，其聲亦變。
When gongs and bells are struck in anger, the sound will be martial; when they are struck in sorrow, the sound will be tragic; when they are struck in delight, the sound will be joyous.
其志誠，通乎金石，而況人乎？」
When the will changes direction, the sound will change as well.
When a person’s will is without adulteration, even stone and metal will be stirred by it—so how much more must this be true of human beings!
