In the wild Longchang, Wang Yangming realized that "the way of a saint is that my nature is self-sufficient", that is, everyone has a conscience. In the bloody battlefield and dangerous court, what gave Wang Yangming strength was the "unity of knowledge and action", that is, by following his inner conscience, he can achieve a state of tranquility within and invincibility from the outside. If the study of mind is the skill of sages, then the unity of knowledge and action is worldly wisdom. The unity of knowledge and action does not come from sudden enlightenment, but is a realm of life that is finally forged through continuous reflection and practice in hardships. After experiencing the humiliation in public, the fear of being imprisoned and waiting to die; the despair of being exiled to the Southern Barbarians, the danger of the plague; the loneliness of the barren mountains and the loneliness of no one, until the ecstasy of enlightenment and the peace of attaining the Tao, Wang Yangming not only found inner peace, but also gradually gained the power to change the world through the "unity of knowledge and action".
