Of course, the most powerful books are religious books. The Diamond Sutra, The Analects of Confucius and Laozi are all books that are easy to give people strength and are not depressed.
But now it's not easy for us to understand.
So I recommend Mr. nan huaijin's explanation of these three books:
What does the Diamond Sutra say?
The Analects of Confucius
Old He Zi said
If you want to go deeper, I suggest reading some books by Southern Buddhism.
Still flowing water
A book in the forest
Or those tantric explicit content:
How to live a carefree life
Tibetan medical psychology
Mr. Yu's book, with little content, is very popular, but it won't give anyone any strength. Suitable for carrying in a handbag with lipstick and condoms (not discriminating against women).
If it is foreign, the book recommended by Roman Roland upstairs is very good. From the who's who, naturally, and from Mr. Fu Lei's translation. I think my friends upstairs will agree that john christopher won't get tired of reading it.
In addition, the book of Roman Roland's friend Zweig is also very powerful and very good-looking.
I guess it is appropriate to watch Yesterday's World according to the landlord's character.
