(Song Dynasty) Li Bangxian's "Saving Heart Miscellanies" says: "Eating can quench hunger, drinking can quench thirst, fear can quell disaster, and enough can quell greed." Today's realization: Forbearance can quell anger, and calmness can quench anger. It can stop delusion, humility can stop conceit, understanding can stop doubt, tranquility can stop impatience, sincerity can stop deception. Laozi said: "Knowing to stop and always stop, you will never be ashamed throughout your life."

Tranquility and tranquility have always been one of the main contents of Laozi's Taoist philosophy. People will face many things in their lives, and excessive persistence in things It will definitely be an obstacle to the progress of people's mind and vision, and will make people excessively paranoid about a corner of the world, making it difficult to see the sky beyond the sky and the people outside of others.

And 'indifferent' (looking down on external objects) can dissolve and get rid of 'madness' (over-persistence). That is what Laozi said: "If you know how to stop, you will always stop and you will never be ashamed."
