Desire is only human, but it must be kept in check. Give in to greed, and you destroy yourself.
There is cause and effect in this world. Humanity follows Heaven, Heaven follows Earth, Earth follows the Dao, and the Dao follows nature. Nature has its own spirit, and so it brings retribution.
Heaven's will and fate are intertwined, each forming its own cause and effect.
When cause and effect fall into chaos, natural disasters emerge and Heaven and Earth tremble.
Desire disturbs one's nature; integrity preserves clarity. Greed disrupts cause and effect, but the fundamentals can still be understood.
A little greed is harmless; when everyone is greedy, even Heaven cannot be fooled.
White silk can be dyed with woad, but woad-dyed silk cannot be printed on.
The good do not fear your deceit. Goodness is not evil, yet it can still be deceived.
