Who can understand the cause and effect in the world, who can be indifferent to fame and fortune in the world, that is, who can clearly see the cause and effect in the world, and who in the world can not insist on fame and wealth.

This sentence is equivalent to what we often say, the causal cycle has its own fixed meaning.

Zhuge Liang said in "Book of Hungry Sons": "Without indifference, one cannot make clear aspirations, and without tranquility, one cannot reach far." This sentence expresses many true meanings of life. Chasing fame and fortune is a misguided approach. Being indifferent to fame and fortune may be ordinary, but it will not lead to mediocrity. Chasing fame and fortune may lead to glory for a while, but the soul will not be free, and one will not be able to live a truly wonderful life. In fact, fame and fortune are external things. In the face of fame and fortune, we must be calm everywhere, neither surprised nor happy; be indifferent to loss, neither sad nor angry. Working hard for fame and fortune is putting the cart before the horse.
