What does it mean to know that the universe is vast but still pity the green grass and trees?

The meaning of this sentence is that even after experiencing the ups and downs of the world and reading all the vicissitudes of the world, when you bend down and see the grass and trees growing, the spring breeze is green, you can still feel compassion.

This sentence comes from "Kuang Yi Ting Kou Zhan" by the Confucian master Ma Yifu. The full text is as follows:

As time goes by, we know how long it has been, and this pavilion is still there in the country. All the soldiers who came here were deserted, and they were in mourning and disorder, leaving behind scriptures.

Already aware of the vastness of the universe, I still pity the green grass and trees. The sky sends bird prints, leaving illusions and human spirits.

This is a state of understanding the vastness of the world, which means that you have understood the vastness and complexity of the world, but you still have not given up your natural love for the subtleties. This is a human nature. For example, some people often disdain small daily things once they see big events. Some people are different. On the one hand, they have seen big things, but their basic humanity has not been damaged at all. What is the fundamental difference between the two types of people? In fact, it is "awe". No matter how great you are, you can't escape the constraints of nature and yourself. Therefore, we should have awe of nature and human nature. ?

The more experience you gain, the more deeply you realize that it is difficult for a person's knowledge and opinions to jump out of his level and attitude. The questions asked and the answers sought also tend to be selfish. If you want to bend down to do something, you must first stand at a high place.
