It means: the sea contains hundreds of rivers because of its wide measurement; The mountain is so tall and straight because there is no worldly desire to intrigue. The last words of couplets-"Da" and "Gang" imply that this noble spirit is the greatest and strongest, and also show the author's supreme integrity. The generosity and honest and frank of this "swing" comes from "no desire". This feeling of tolerance and "no desire" and lofty spirit are indispensable elements of mental health.
"Haina" is a metaphor of tolerance. Jin's preface to the famous ministers of the Three Kingdoms: "The shape of the instrument does not exist, and the square inch is Haina." Li's note: "A heart of square inches is full of rivers. It is said to cover a wide range. "
"Hundred Rivers" is the general name of Jianghuai Lake Ze. "Tolerance is great", from Shang Chen Shujun: "Tolerance is great." Shanglian means that the sea is vast because it can accommodate all rivers and streams; People's virtue should be broad, but also have a broad mind like the sea. Forgiveness has won many people. "Only kind people can be lenient" (Song Chao's "The Story of Glory to the Stone").
With a broad mind and tolerance, we can "tolerate the things that are difficult in the world" and "tolerate everything" with others and ourselves. This kind of tolerance for others is the "forgiveness" advocated by Confucianism, that is, treat people kindly and put yourself in their shoes, and "don't do to others what you don't want them to do to you" (The Analects of Confucius Yan Yuan).
"If you want to be a man, you want to be a man" (The Analects of Confucius, Yongye). This sentiment of unity between man and himself is not only conducive to personal physical and mental health and realm improvement, but also can adjust the relationship between people and achieve a reasonable and harmonious situation.
The first couplet is open-minded when explaining what is big. Big is a whole composed of countless small parts, which can accommodate things that are difficult to accommodate in the world. Being able to accumulate and learn continuously is a profound knowledge; Everything that exists in the universe is bound to happen in people's consciousness and activities. It is of great significance to try to understand different fields, and the greatness and smallness of people are also here!
Where does the indomitable ambition come from? No desire is just. Everyone has worldly desires, and excessive love for something will lead to personal loss and misguided. Wang Bo once said, "If you are poor, your country will be strong, and the sky will never fall." Zhuge Liang also said, "Be indifferent to your ambition, and be quiet and far-reaching.". Confucianism pays attention to self-cultivation, governing the country and leveling the world, while Buddhism also forbids "greed and stupidity" to improve your personal realm.
Only by breaking through fame and fortune, lust, material desire and control desire can we make our ambitions clear and stick to the right direction. In an impetuous environment, some people become political dictators, black-hearted corporate capitalists, and pursue academic research of fame and fortune. Gradually, human nature becomes distorted and life becomes meaningless.
