Wang Yangming is a rare thinker in the history of China. He firmly believes in the idea of being at home. Wang Yangming believes that "it is easy to break a thief in the mountain, but difficult to break a thief in the heart." The main reason is that it is difficult to control all kinds of greed in my heart.

Wang Yangming's outstanding achievement was to wipe out the bandits at the border of Hunan, Guangdong, Fujian and Jiangxi provinces. At that time, thieves were everywhere in these areas. They were entrenched in the mountains at the junction of two provinces or three provinces. They were easy to defend but difficult to attack, and they also extensively developed their internal affairs. The government could know in advance what it did, and the thieves were so rampant that the former governor Vincent had to resign due to illness. However, after Wang Yangming took office, relying on his outstanding military talents, combining suppression with appeasement, selecting elite soldiers, making a diversion from the East to the West, and establishing ten card methods, it was a miracle to wipe out thieves who had been suffering for decades in just a few months.

In the face of such contributions, Wang Yangming thinks that "it is easy to break the thief in the mountain" and clear the thief in the mountain, which is easy to solve, and there is nothing to boast about; In his view, there is something millions of times more difficult than breaking a thief in the mountains, and that is-breaking a thief in the heart. The so-called "thief in the heart" can be said to be four kinds of thieves: name, profit, power and color. A thief is a good name. This is most prominent in literati and scholars.

Since there are so many thieves in people's hearts, we should try our best to eliminate them. There are three ways to break the thief's heart: First, sit still. The sit-in mentioned by Yang Ming only strives for fame, profit, power and lust, so he wants to recover the lost hearts through sit-in. Second, tempering things. The so-called tempering things is to temper one's own mind and eliminate the hearts of good fame, profit, power and lust in the process of dealing with others and things. The third is to conscience. If meditation is hard work when it is "quiet", and physical training is hard work when it is "moving", and it is divided into static and dynamic, then the conscience is to combine static and dynamic.
