Bodhi has no trees, and the mirror is not a stage. There was nothing, so there was no dust. Everything is empty. Nothing in the world is difficult for one who sets his mind to it. Advise everyone not to be persistent. Sometimes, understanding the development history of Buddhism can help us to understand the contents of Buddhist classics more deeply, and the same is true for understanding the meaning of "Bodhi has no trees, mirror is not Taiwan, there is nothing, where there is dust". "Bodhi has no trees, the mirror is not a stage, and there is nothing. Where can it be dusty?" It is a poem written by Huineng, the sixth ancestor of Zen Buddhism. Through this poem, Huineng established his position in Zen, and Zen also established its final position in China. Zen was first introduced to China from Dharma. It entered as an unknown faction. At that time, the famous and dominant factions were Legalists and other factions. However, Zen has made great progress in China and eventually became the mainstream of Buddhism in China, which is related to the contribution of Huineng, the sixth ancestor of Zen. Huineng, the sixth ancestor, is an epoch-making figure in the history of Zen. Because in the era of Huineng, the sixth ancestor, there was an important debate within Zen Buddhism, that is, whether Buddhist practice was "self-cultivation" or "cultivation of mind". This argument is expressed in two poems by Shen Xiu and Hui Neng. The school represented by Shen Xiu believes that it is difficult to become a Buddha without personal efforts if one wants to cultivate one's morality and become a Buddha, that is, the idea summarized in the so-called "being a bodhi tree and having a heart like a mirror". In other words, to become a Buddha, you should practice, "always wipe, not make dust", and avoid being contaminated with the "miscellaneous dyes" in the world. This was the mainstream thought of Zen at that time. Huineng laughed at Shen Xiu's incompleteness. His view is that since Shen Xiu admits that "everything is empty", isn't your body "empty" too? Since your body is also "empty", what do you "always rub"? Therefore, Huineng thinks that Shen Xiu's view is wrong. Huineng advocates "cultivating the mind" to become a Buddha, that is, the thought of "Bodhi without trees, mirror without platform" summarized in the poem. Huineng said that only by solving the problem of mind can we become a Buddha. Because the body is "empty" and the "mind" is real, practice can only be to cultivate the mind. Huineng's son represents such a theoretical system. Huineng Masako's theoretical significance lies in his most satisfactory exposition of the true meaning of Sakyamuni Buddha from the perspective of Zen. Sakyamuni Buddha believes that the so-called "Buddha" is "enlightenment", and people can become Buddhas when they wake up. But how to achieve it, Sakyamuni Buddha did not say. Huineng tells people that the enlightenment mentioned by Sakyamuni Buddha lies in an idea in people's hearts, which is called "epiphany". This is indeed the most accurate embodiment of the essence of Sakyamuni Buddha's thought. In fact, the so-called "put down the butcher's knife and become a Buddha on the spot" is a proverb formed by this idea and the most typical concept expression. The emergence of Huineng theory actually marks the highest development stage of Buddhism. And defeated other schools of Buddhism in China in theory. In a short time, other sects of Buddhism in China basically disappeared. Therefore, "Bodhi has no trees, the mirror is not Taiwan, there is nothing, where can it cause dust" is so famous because this poem is a milestone in the history of Buddhism, and Zen has become the mainstream Sect of Buddhism in China at this time, and it is also the representative of the highest stage of Buddhism development. Some Buddhist scholars believe that it is precisely because of the formation of Zen Buddhism that the highest stage of development of Buddhism was actually completed in China. This can also be used to explain why Buddhism finally disappeared in India, that is, Indian Buddhist disciples did not complete the mission of finally perfecting Buddhist theory, so Indian Buddhism could not compete with other emerging religions and was eventually abandoned by Indian society. Of course, after Huineng, Zen developed. For example, Zen master's "Reading Buddha and Resenting Ancestors" in Deshan Xuanjian said: "I have no ancestors and no Buddha here, and the founder of Buddhism is an old man who feels ashamed of himself. Bringing Huineng's thought to the extreme is a typical example. But despite the extreme, I still didn't jump out of Huineng's thinking track. It also reflects the fact that after Huineng, in theory, there is no one beyond Huineng in Buddhism. That's about it.
