Original text: "My life is also limited, and my knowledge is also limited. With restrictions, there is no restriction, and it is almost there! It's almost enough for people who already know! Good has no near name, and evil has no near punishment. The Governor thinks that he can protect himself, support his relatives all his life, and work for many years. " -"Zhuangzi, the third health proposition"

Our life is limited, but our knowledge is infinite. Then using the limited to pursue the infinite will make people tired and hurt.
