When I lived to be in my fifties, I suddenly realized that life was all about. All beings in the world come and go, one more, no more, one less, no less. There are people who are selfish and have no conscience. Such a person, if you don't eat hard and soft, you can't change it at all.
But no matter what, you have to convince yourself that you can't be angry with such people. When you can't carry it, find a place where no one is around, and then wipe away your tears and continue to live. If you live and live, you will find that the more people live, the more they can carry things.
At what stage of life there are troubles. Everyone is basically the same. Some people see that they are more open, live more transparently, and their lives will naturally be happier. Some people are small-minded and love to drill the horns. The days are always twisted, and in that case, there will be more suffering.
In fact, life is a few decades long. No matter how capable a person is, it is impossible to live forever. A few more years and a few less years is a lifetime. When you are alive, you should live well, and it will be convenient for others and yourself. Regardless of whether there is such a thing as reincarnation or not, we must live with good intentions.
