Because suffering forces people to change, they force people to give up those stubborn ideas that they think are right. If you change, you will live; if you don't change, you will die.
But if it is painful and does not change, it is the greatest pain in life. Change is a virtuous circle, and unchanged is a vicious circle.
Because life is a process of constantly adapting to society and improving itself, pain is inevitable.
Some people take the initiative to deal with these pains. They use self-control and willpower to prepare in advance for the coming of pain; some people passively endure these pains, and when they come, they use their patience to overcome them. Whether it is to prepare in advance or to deal with it afterwards, it is certainly not an easy process. But this process is often also a process of social progress.
The day when human suffering completely disappears, I am afraid that it will not be far from the end of humanity, because such a human society may not have any forward momentum. It is precisely because of this that we say that we are born in sorrow and die in happiness.
So why do people suffer? That is because nature forces us to make changes. Whoever makes the first step to adapt to the natural changes will have a little bit less pain; whoever makes the appropriate changes later will have a little bit more pain.
But in any case, it is definitely a constant fact that all living beings suffer; on the other hand, pain and happiness are also constant facts.
So Luo Yan Luolan said that there is only one kind of heroism in the world, that is, after recognizing the truth of life, still loving life.
