The author feels about himself in the palace and the chaotic world he lives in, and pursues a calm and optimistic life that is free from passion and desire. In the book, Marcus Aurelius elaborated on the relationship between the soul and death, analyzed personal virtue, personal liberation, and personal responsibility to society. He required frequent introspection to achieve inner peace, abandon all useless and trivial thoughts, and think with integrity. And, not only think good and aboveboard things, but also act on them.
