Inheriting Lu Jiuyuan's theory and carrying forward Lu's thought, it is called "Lu Wang School". Based on the theory of "mind is reason", Lu Jiuyuan thinks that the place where things start is to realize the truth. Wang Shouren was dissatisfied with Lu Jiuyuan's explanation. He said: Lu Xiangshan's learning, "he knows speculation and the language of things, although he is tired and does not follow."

Oppose Cheng's method of "seeking the ultimate truth through things", because things are endless and unique, which is too tiring. Therefore, he advocated seeking the truth from his own heart, believing that the truth is in his own heart, and the truth is transformed into all things in the universe. People have grasped its subtlety, so people have grasped its essence.

As Lu Jiuyuan said, "The heart is rational and the heart is rational." Why not look outside? Therefore, it is obvious that "initial heart" is clear about "heaven". Therefore, Wang Shouren emphasized: "There is only one heart, which means benevolence in terms of all its troubles;" As far as its appropriateness is concerned, this means righteousness; As far as its organization is concerned, this means reason. Can't seek benevolence, justice and reason from outside? This knowing and doing is two because it seeks truth from the outside; Seeking truth from my heart, this holy gate is the teaching of unity of knowledge and action. "
