It is said that to cultivate self-cultivation, we must first correct our mentality, because anger can't correct our mentality; With fear, it is impossible to be right; With preference, it is impossible to be correct; You can't be right if you have concerns. A bad heart is like a heart that is not on you: although you are looking, you don't seem to see it; Although listening, I don't seem to hear it; Although I am eating, I don't know what it tastes like. Therefore, to cultivate self-cultivation, we must first correct our mentality.
