Calmness is a kind of rationality, a kind of perseverance, a kind of tolerance, a kind of style, a kind of optimistic attitude towards life, and a kind of transcendent realm of life. Each of us needs this kind of mentality, so that we can be calm in life, be unfazed by favors and disgrace, not be too excited and forget ourselves, nor be too sad and miserable. In life, we are often affected by the environment and dominated by our own bad emotions. We feel that life is very hard, and our spirits are increasingly empty. Because, while we are constantly pursuing material interests, we forget about spiritual provision; while we are constantly pursuing "gain", we are also losing at the same time.
