This couplet is from the 37th visit to Cao Lu, Ergun.
This is how people with moral cultivation exercise themselves. They perfect themselves through meditation and introspection, and cultivate their noble character through thrift and saving money. Without a clear heart and desire, you can't make your ambition clear and firm. Without stability and tranquility, you can't realize your lofty ideals and study hard for a long time. To learn true knowledge, we must study and discuss it peacefully, and human talents are accumulated from continuous learning; If you don't study hard, you can't grow and develop your talents; If you don't have firm will, you can't succeed in your studies. Indulgence and negative neglect can't cheer up the mind; Taking risks rashly and being impatient can't cultivate your character and make your moral integrity noble. If we waste it year after year, the volunteers' time will eventually become as old as dead leaves. Such people will not be used by society, but will benefit society. They will only be trapped in their poor home sadly, and it will be too late to regret it.
For example, Tao Yuanming and Zhuge Liang
Indifferent ambition: it means that only by not pursuing fame and fortune can we make our interests noble and noble. Indifference: a simple life.
