1. To keep a normal mind is to be neither arrogant nor impetuous, to do things with the heart of joining the WTO, and to keep a normal mind is to feel that shame under the pressure of modern stressful life. Before the idle flowers fall into the court, look at the sky outside the clouds! 2. The so-called normal mind is just a state of mind in dealing with things around us in our daily life. Normal mind should be a "normal state", which can only be possessed after a certain accomplishment, and belongs to a "philosophy of life" that sustains life. As Mencius said, "Benevolence is human heart, righteousness is human way." In the final analysis, the normal mind is just the confluence of ideas such as "inaction, no dispute, no greed and contentment". As an attitude towards life, it can be further interpreted as indifference, humiliation or kindness ... However, "inaction" does not mean advocating inaction, and "not fighting" does not mean cracking down on evil forces ... As for what some people pursue, it cannot be regarded as a realm of life, as the author commented: "When they reach the realm of pure self-care, it is morality. Vulgarizing, secularizing and simplifying the normal mind is a misinterpretation of the original intention of the normal mind. 3. Classically, our hearts are like waterfalls, constantly thinking, just like choppy waves. It's really difficult to keep a calm and normal heart. What is a normal heart? It is a state of mind, "don't be happy with things, don't be sad with yourself", and don't be happy or worried about environmental changes; Normal mind is a state. Master Huineng said, "There is nothing. Where did the dust come from? "It transcends things and transcends itself. There are four kinds of normality here: First, it is normal to do good: no matter what you do or do good, if you persist, you will be hindered; With persistence, there will be expectations. When expectations fail, you will be disappointed, even angry and uneasy, and your heart will not be calm. If you can do good deeds, do good to others, ask for nothing in return, and don't stick to your heart, you can achieve "three rounds of emptiness", and the pure and equal heart of those who give, receive and give is the normal heart. Second, it is normal to die of old age without fear: the cycle of life and death is the normal way of the universe. People will inevitably get sick, face aging and even die, but they can be fearless, unshakable and feel at ease. The so-called: "Death is the beginning of life, and life is the preparation for death; Life is never born, and death is never dead. "This is called normal heart. Third, it is normal to ignore losses: there is a saying: "Learning to lose money can cultivate morality. Sometimes it's not a bad thing to suffer. You can accumulate life experience from loss, and you can learn to yield to the world from loss. Especially when people get along with each other, it is inevitable that there will be injustice and debt. It is normal to be able to ignore and compare when suffering losses. Fourth, it is normal not to be troubled by adversity: as the saying goes, "If there is no yen in the month, there will be no good days in the day. When we meet the realm of disobedience, we should be able to see our troubles clearly, put them down, not dance with them, and deal with them calmly. For example, in a game, you always want to beat your opponent. In fact, to defeat your opponent, you must first defeat yourself. To overcome yourself is not to be disturbed by the environment, trapped by other thoughts, moved by adversity, forget your opponent, forget winning or losing, and treat it with a natural attitude. This is the normal state of mind. " Men want nothing, and their hearts are good; If the heart wants nothing, people will feel at ease. In fact, "normal mind" is a persistent mind that takes nothing, gives up nothing, is neither arrogant nor impetuous, and asks for nothing in daily use. As the saying goes, "the most common things are the most magical, and those who know nothing about all kinds of mysteries and seek Tao in succession have doubts about their meaning." "The last chapter revealed that the normal mind is the Tao, and the Tao is in ordinary life. The above normal mind can be used as a reference for our life. First, it is normal to do good, second, it is normal to die of old age without fear, third, it is normal to suffer losses, and fourth, it is normal not to be troubled by adversity.
