What is the meaning of the ancient words "to leave the world" and "to enter the world"?

The concepts of "leaving the world" and "entering the world" were originally derived from the doctrinal concepts of Confucianism and Taoism, which advocated active participation in the world, helping the world, and contributing to society, while Taoism advocated living in seclusion in the mountains and forests, such as Lao Tzu's "old age and death are not to be associated with each other".

Later, this concept was extended to other people, representing two different outlooks on life. Entering the world is a positive outlook on life and the world to integrate into society, while leaving the world is a negative outlook on life and the world to escape from the society, such as the peach blossom garden in Tao Yuanming's "The Story of the Peach Blossom Garden".

To be liberated is to leave the world, and not to be liberated is to enter the world. If one's mind is free from liberation, whatever one does, wherever one is, one is in the world. Therefore, if one can at the same time develop the bodhicitta mind to realize all sentient beings, then one is doing things in the world with a mind that is in the world. That's why it is said that ordinary people cannot actually have a worldly mind because their mind is not liberated. If one wants to reach this level, then one still has to focus on one's own cultivation, or else one is likely to still be doing good things in the world with an initiatory mind. Of course, even so, more good deeds are still worthy of praise and encouragement, as long as the heart of the Dharma this good deeds will also be able to get the heart of the future liberation, truly out of the world to lay a good foundation.
