What is the enlightenment from talking with the last four sentences of Zhu Yuansi's book?

I have a feeling after reading The Meaning of Life

Time flies, time flies, and in the infinite universe, only one creature has its goal. They pursue their dreams and cut through thorns. The stormy waves can't stop them from moving forward, and the mountains and dangerous peaks also make them fearless. They are great human beings.

The Meaning of Life shows us that there are four stages in the course of life, including physical layer, biological logic layer, biological culture layer and value layer. People's life can't get rid of the laws of physics after all, just as no matter how high we jump, we still have to land under the action of gravity, no matter how far we can jump, we still can't get rid of gravity and jump out of the earth. In the biological logic layer, we know that there are thousands of different creatures besides human beings. One of the characteristics of * * * is that they are all alive. Therefore, none of us can live without the control of biological laws. People are different from other creatures, that is, there are cultural exchanges between people, and there are different life cultures from country to country and from home to home. They interact with each other, and * * * is isomorphic into the biological and cultural layer of life. Man is conscious, and he can grow by communicating with others.
