What are the four sentences realized by Buddhism?

Dharma realized four words from the wall: everything is ready, everything is complete, everything is fresh, and everything is beautiful.

Father Dharma has been facing the wall in Songshan Mountain for nine years, and his peace of mind is facing the wall. The second phrase is called "Ruofa" and "Ruofa four lines". The third formula is called "go with the flow", "go with the flow, and you will be free from ridicule". The fourth formula is "if it is convenient" and "if it is convenient, you can't send it away".

The story of Dharma Face Wall:

Dharma, the founder of Zen Buddhism, started his own way of facing the wall after crossing the river with a reed. In fact, the nine years facing the law wall is not what most people call a "journey of cultivating immortals", in which many sad stories have happened, threatened by fire, wolves and leopards, and the road to seeking the law is full of thorns.

At the beginning, the face wall of Dharma was not all day, but also gave lectures at the temple in the evening. After a while, Dharma became addicted to the wall and began to sit cross-legged in front of the stone wall all day, "closing his eyes and having no distractions", which lasted for nine years.
