How to understand "if a person shows the moon with his fingers, he should look at the moon because of his fingers"

"If a person points his finger at the moon, he should look at the moon because of his finger." It means that the so-called yogi looks at his fingers more often than at the moon, and because of confusion, he identifies his hand as the moon. For example, the Diamond Sutra says, "If you know what I said is like a metaphor of a raft, then the law should be abandoned, not to mention illegal." Interpretation: the raft means also, and the other side means the moon. When you reach the other shore, you don't need a boat, that is, you see the moon and you don't look at it anymore. There are many ways to do things. Some practitioners read more classics and want to be a great scholar instead of practicing. For example, the Shurangama Sutra: For example, Ananda, although he has heard a lot, if he does not practice, he will not hear it. If people say they eat, they will never be full. If you smell more, you are serious. Practice is the process of observing the moon. When you see the moon, you will become a Buddha. If you don't eat, you can't eat. If you don't practice, you can't become a Buddha. "Grinding bricks can't make a mirror, and meditation can't make a Buddha." Master Dharma Zen came to the West and reprimanded the practitioners in this area, who were obsessed with meditation rather than practicing Buddhism, which was an important manifestation of pointing to the moon and looking at their fingers.
