The Buddha touched a flower and smiled. When he laughs, it is not a process, but a static state. In this static state, a person touches a flower with his hand and looks at it quietly with a smile, but he can't see what he is thinking, but he can only appreciate it quietly. Look at this simple and quiet scene, not guessing what Buddha is laughing at, not guessing what Buddha is laughing at, not guessing what secrets are in the flowers.
This kind of scene is very comfortable and can calm the heart. This scene has a heart-wrenching effect, just like being in a daze quietly, but it is different from being in a daze. Ordinary people are in a daze, thinking about things, giving onlookers a dull illusion that their hearts are actually turning;
Mahakasyapa is motionless, watching quietly, without paying attention to his mind, while the Buddha smiles at the flower, and Mahakasyapa smiles at the Buddha's flower, so when the Buddha says that Mahakasyapa has understood, he actually means this extremely meticulous and peaceful state of mind, which is beyond the realm of all things.
Extended data:
There are two stories about the origin of the story. One is that the Buddha picked a flower from a flowerpot when he was in class. Another way of saying this is that the Brahma King presented a precious golden Borneo flower to invite the Buddha to give a lecture in jiusan. But it doesn't matter. The development of the two versions is that the Buddha is touching the flowers, and the treasure is solemn, but he seems to smile without saying a word, as if to imply something.
Of course, the disciples understand that the Buddha's action contains profound meaning, but only the great disciple of the Buddha, Mok Ye Jia, can really understand it. The venerable Ye Jia smiled through tears, which puzzled all the monks. However, the Buddha knew that Ye Jia knew Zen. He said: "I have the Dharma, hidden eyes, wonderful heart, no reality, subtle practice, no writing, no telling people, and giving instructions to Mahayana."
This means that I have a good way to understand Buddhist scriptures, and I have just taught it to the venerable Ye Jia. If you want to know, learn from him. It is said that the Buddha also gave Ye Jia his cassock and alms bowl. This is the story of "the true story of clothes". Therefore, Zen Buddhism listed Mahagaya as "the first ancestor of the Western Heaven". It is said that this is the beginning of Zen.
