Without compassion, we can't feel the pain and happiness of others, and we can't communicate with others normally. Think about it, you hate eating durian, but your friends insist on eating it and feel nutritious. You are immersed in the pain of lovelorn, but people around you insist that you tell him a joke. So you can't get along with him. Autistic people can only live in their own world and have no social skills because the function of the area of their brain that is in love with others is damaged and they can't perceive other people's emotions.
Because of human emotional ability, we can support each other, and individuals can face the difficulties in survival together with the help of collective strength. As a species, human beings can continue on the earth. Without emotional ability, business activities are basically impossible. Because businesses don't know what customers like. How to improve people's emotional ability can be said to be the ultimate goal of religion, art and other literature. Christianity requires believers to "love others as themselves", while Buddhism regards the achievement of great compassion as the ultimate achievement of practice. The so-called "no pity, no pity". We ordinary people are more sympathetic to our brothers and sisters than passers-by. Buddhism advocates sympathy for all people and even all animals.
When you see the pain of others, you will suffer from your inability to help them. It shows that you are very compassionate. Personal strength is limited. If you try your best to help others and pass on this spirit, the pain in society will be much reduced. At the same time, we should also realize that people will experience many pains in their life, including birth, illness, death and various accidents, which are difficult to eradicate by external forces. Some pains can only be borne by psychology. If we show sympathy for each other, we can also make him accept the pain he has to face, which can also alleviate his inner pain.
