What practical psychological knowledge is there in life?

Buddhism often says that impermanence is the truth of the world and the essence of life. Therefore, understanding impermanence is not to escape from reality, but to recognize the greatest reality of life and the whole reality. People always regard impermanence as an obstacle to life and an invisible killer to destroy happiness, all of which are caused by their wrong ideas. If you can thoroughly understand the nature of impermanence, you won't suffer from impermanence.

Life is impermanent. Physics is successful, alive, broken and empty. Birth, life, change and destruction of psychology; Physically, life and death. If we can thoroughly understand these truths, people will not care about them; I don't care about people's right or wrong. Naturally, I can concentrate on Tao, and I won't be tempted at will in real life!

People are born unreasonable, illogical and self-centered. Life is always impermanent, with ups and downs. Many people say they don't know what they want. In fact, the real meaning of this sentence is that they don't have the courage to face it and don't work hard enough to get what I want.
