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.

For those who reflect on themselves, everything they encounter is medicine. For those who attack others, every thought is a weapon. One is the way to initiate all good, one is the way to deepen all evil. They are as far apart as sky and earth.

Diligence means to be keen in matters of virtue and justice, but worldly people use diligence to solve their economic difficulties. Frugality means to have little desire for material goods, but worldly people use frugality as a cover for stinginess. Thus do watchwords of enlightened life turn into tools for the private business of small people. What a pity!

Generosity should begin lightly and deepen later, fro when it is first rich and then lessens, people forget the kindness. Authority should begin strictly and loosen up later, for if it is loose first and then strict, people will resent the severity.

Warm weather fosters growth: cold weather destroys it. Thus a man with an unsympathetic temperament has a scant joy: but a man with a warm and friendly heart overflowing blessings, and his beneficence will extend to posterity.

Blessings often give rise to injury, so be careful when things are going your way. Success may be achieved after failure, so don't just give up when you've been disappointed.

Human affairs are like a chess game. Only those who do not take it seriously can be called good players.
