Confucius climbed the East Mountain, and Xiao Lu made the following sentence.

Mencius said in Mencius: "Confucius climbed the East Mountain but was small, and climbed Mount Tai but was smaller than the world. Therefore, it is difficult for people who look at the sea to swim in the water, and it is difficult for people who swim in the holy gate to say. If you have the ability to watch the water, you must watch its glory, and the sun and the moon will shine. Running water is also a thing, but it is not a mirror; The ambition of a gentleman is also in the Tao, and it cannot reach the chapter. "

Mencius said: "Confucius climbed Mount Meng and thought that the whole country of Lu had become smaller. He climbed Mount Tai and felt that the whole world had become smaller. Therefore, it is hard for people who have seen the sea to see other waters, and it is hard for people who have studied saints to hear other remarks. There are certain ways to see water. You have to watch its big waves first. The sun and the moon can shine into a small gap. This kind of thing, running water, will not advance unless the pit is filled; The ambition of a gentleman, pursuing the avenue, is not accessible until a certain stage. "
