What kind of realm is "not happy with things, not sad with yourself"

Don't be happy with things, don't be sad for yourself: don't influence everyone's mood and mood with the surrounding environment and scenery, and don't influence your mood with your own situation, status change and migration. It means to focus on the following sentence (like the ancient benevolent heart) Worry about the world first, and enjoy it later.

Don't feel happy or sad because of the quality of foreign things and your own gains and losses. We should take the affairs of the world as our responsibility, and only have the country in our hearts, so that you can worry about my humiliation and humiliate my death.

Don't be happy with things, don't be sad for yourself, not only means looking down on everything, there is no difference, etc. , but also a realm beyond the secular. When a person yearns for his heart and is willing to give his life for it, and all external things are just tools to assist him, he really reaches the realm of psychology and actual combat training. At this moment, all external things: communication, capital, relationships, emotions, etc. They are all external elements that linger around you to help you cultivate your mind. Only you know your own attributes. The attribute of the heart. Of course, the premise is the essence of your heart. It must be positive, lead people to do good, and conform to the objective laws of heaven.
