From a psychological point of view, why are all monks and nuns now monks and nuns?

The entry foundation of Buddhism is "alienation", that is, leaving the six divisions in the wheel of the heart of karma.

Why do astronomers look for a second Earth or actively explore emigrating to Mars? Because the earth may not be able to carry human beings in the future, there are many reasons, such as excessive population expansion, environmental deterioration, lack of resources, celestial disasters and so on. This is also a kind of "alienation", because the existing living environment is not beautiful enough and there is no ability to change it, so we should seek a better place to go.

Buddhism is a similar thing from a broader perspective: because we suffer from the six divisions of the Karma Wheel, we have no ability to change the six divisions of the Karma Wheel. Therefore, people who study Buddhism need to leave the six divisions in the wheel of karma, go to a place where there is no reincarnation, that is, the clean world of buddhas and bodhisattvas, learn the ability of being born without forbearance, and then come back to save all beings. The alienation in Buddhism is based on the following factors: first, how rare it is for us to practice Buddhism; Second, how impermanent and perishable our lives are; Third, reincarnation, especially the drama of hell, is unimaginable (a humane life has eight kinds of sufferings, and death is the greatest suffering); Fourth, the law of causality is so selfless.

To some extent, practicing in Buddhism is a process of tempering psychology. The real becoming a monk is becoming a monk with the heart, that is, the heart is no longer attached to the existing world, including not greedy for love or hating. This is a peaceful middle way psychology. If the earth becomes no longer suitable for human habitation, once human beings move to other planets, future generations of human beings will gradually forget the earth.

If you want to know how a true Buddhist temper his mind, how to turn a greedy, ignorant and dull heart into purity, and how to turn a heart that treats everything differently into equality and compassion, you can find a temple with short-term experience of becoming a monk. Or find a video on the Internet to explain Buddhism, which is actually a way to change your mentality.

Generally speaking, becoming a monk is to better practice Buddhism and inherit Buddhism. Of course, there are also many people who have no chance to choose to study at home, as long as they really become monks. Some people don't understand Buddhism and think that becoming a monk is passive seclusion, which is like opposing the search for a second earth.
