Paul is about to return to Kiev after his illness. He came to the tomb of the martyrs to mourn his revolutionary comrades. The passage from "man's most precious life" to "everyone can end his own life" is a life principle that Paul abides by all his life and is also the central idea of the book.
This passage has become an oath that represents the spiritual pursuit of revolutionary youth for decades.
After reading the article "The Meaning of Life", I understand a truth: life can't be twice. Since you have been to the world once, you should cherish the value of life, don't face death, give in to death and pursue happiness. Without the pursuit of happiness, life is meaningless. Even if there are only a few minutes left before death, make yourself happy, do something meaningful and go to heaven happily.
