How to treat the sentence "a loss is a blessing" Tell me.

If we understand this level, I think it is still superficial, because it is just a question of "losing is happiness". We need to know more about it. Laozi once said, "it is not because of selflessness that one can be selfish", which means that one can be selfless, but he has achieved himself in the end. Look at the people around us, those who are dedicated to the public and selfless, and they will live a full life. The so-called "private" is your ideal and ambition, which belongs to the spiritual aspect. The completion of the ideal, the realization of the ambition, and everyone's help, and finally completed smoothly, this is personal settlement. Tell us that a person should not haggle over every ounce on the material level and feel how much he has suffered. In fact, what we get is the spiritual part, which is intangible and bigger than the material part.
