Many saints have said that they are closed to the outside world, but what are they doing?

We often hear or see a master shut the door in TV series, so what are they doing? The word "behind closed doors" means to shut yourself in a set room, not to go out and not to care about the world, only to care about your own land. The original intention of retreat is to let those who retreat, that is, those saints, devote themselves to practice, learn to think and exert their great potential in a relatively difficult environment.

The explanation of the word "shut the door" in Buddhism roughly means that the closed door closes one's six roots, as well as one's body, mouth and heart, so that the closed door's heart is not disturbed and polluted. During the period of retreat, those who retreat will concentrate on practice. For people who have been closed for a long time, even eating is simplified a lot, just to have more time to study and think, and not to let secular life interfere with and occupy the brain. In this way, those saints behind closed doors can devote all their time, energy and attention to practice.

Those closed-door saints read books in separate rooms, sometimes inside, like Buddhism, like Confucianism, and read four books and five classics. Sometimes I write, for example, when reading a book, or write a summary like a class note. Of course, sometimes they will sit still in it, which is equivalent to meditation, that is, they will focus on their own hearts, taste and reflect on themselves.

The retreat of many saints shows that they can endure monotonous life and relatively difficult living environment, and retreat is an excellent opportunity to exercise their mood. During this period of seclusion, those saints who are behind closed doors can improve their knowledge, hone their mood, and learn to look at themselves, others and life from another angle.
