A clear sunny day can suddenly shift to thunder and lightning, a raging storm can suddenly give way to a bright moonlit night. The weather may be inconstant, but the sky remains the same. The substance of the human mind should also be like this.

Diligence means to be keen in matters of virtue and justice, but worldly people use diligence to solve their economic difficulties.
