Wang Yangming's theory of mind can be roughly divided into three parts: the theory of life that "the heart is reason"; the theory of knowledge that "unifies knowledge and action"; and the theory of cultivation that "cultivates conscience". He believes that the heart is the master of all things in the world. There is no reason and nothing outside the heart. This is also the basic point of his theory of the heart. Knowledge and action must be unified, words and deeds must be consistent, and everyone must practice conscious ethics. Any external actions or things are controlled by thoughts, and everything is unified in the heart. The source of good and evil is people's own hearts. Starting from "conscience", everyone is equal, and mortals can also become saints.

It aims to combine it with modern ideology, so that readers can not only understand the wisdom of Yangming's mind and master its fundamental spirit, but also effectively practice it in real life, cultivate and strengthen their hearts, and resolve the worries in life at any time.
