Finally, the teacher's comments:

You have all seen the process of completing this flute by Cai Youyou, it was completed according to the method I taught, it can be called perfect, with only two small flaws. From the appearance of the very detailed, not even a little rough, although the quality is not good, that is subject to the material. The alloy I used for you to practice was scrapped from the intermediate class, and you are just practicing, so it is impossible to give you good materials. So I give the demon this flute 95 points.

The most important thing I want to emphasize is: Cai Youyou's mastery of the hammer. Holding a 50-pound hammer in his hand, he has achieved a light weight, a light weight, flexibility, and accuracy. There are places where he can set the mark, and many of you can't. You may have to hit it twice, three times, or even scrap, and you may have to return to the furnace, and the number of refurnaces will lead to a decrease in the quality of the alloy. This is what we have repeatedly emphasized, the physique, strength, accuracy, durability, and melting strength of a forger are the foundation of what makes a senior forger, and the key is the key.

"Classmate Cai Youyou, you have passed the flute casting class this time. You're good to go. Tomorrow, the day after tomorrow can not be used. The fourth day is a class on "Retention and Sublimation of Mineral Aura", and you are coming. "The teacher has given the order to evict the guest.

The demon was unwilling to leave, and paid so much tuition. The demon asked again if there were 2 steps to forge a flute and if it could be combined into one, and there were 3 steps to reverse the order. The answer given by the teacher is: beginners do what the teacher says, and when they are proficient, they do it according to the demon's own ideas.

The demon calculated, three days of class let me take 2 hours, the school is 20 taels of silver a month, and the three-day tuition fee is 2 taels of silver, which is a big loss. The demon was very depressed, and he had to get the two taels of silver back.

If you can't take a casting and forging class, you will take a physical fitness class. The demon interjected into the class, which was skillful and skillful, and the result was nothing, and the demon went to listen to history and geography classes. The demon felt bored, so he had to go to the library and continue to flip through the books.

The demon continued to study. "Wen Shi Zhenjing" Seven cauldron kettles, turn also.

Guan Yinzi said: The Tao is nothing, and those who return to the Tao with things will get a rest; ①

The Venerable One who has attained the Tao can assist the world, and the only one who has attained the Tao can establish me. ②

Those who know that they can be restrained by time can take one day as a hundred years and a hundred years as a day, and those who know that they can hinder it can take one mile into a hundred miles and a hundred miles as one mile. ③

Those who know that there is no qi can be lucky, and those who know that the invisible can become tangible, can change birds and beasts. ④

Those who have attained the Tao can not get tired, and their bodies are light, and they can ride phoenix cranes; those who have attained the Tao can drown in things, and they can sit on the whales. ⑤

There is nothing, there is nothing, and those who know this way can control ghosts and gods. The real is the virtual, the virtual is the real, and those who know this way can enter the golden stone. Up is down, down is up, those who know this way can serve the stars. The ancient is the present, the present is the ancient, those who know this way, can divinate the turtle. People are me, I am people, and those who know this way can peek into the lungs and livers of others. The thing is me, I am the thing, and those who know this way can become the dragon and tiger in the womb. ⑥

Knowing the image changes from the heart, and by contemplating the mind, you can become a baby girl; With this victory, the tiger and leopard can be ambushed, and with this same thing, water and fire can enter. ⑦

Only a man of the Tao can do it, and he can do it without doing it. ⑧

This passage is a bit long, so it is divided into 8 sentences.

(1) The first sentence talks about the relationship between things and the Tao. The Tao is summarized from things, and the Tao can be applied to dealing with things.

(2) The second sentence says: Those who have obtained the "Tao" can help the world when they enter, and they can be good to themselves when they retreat. It is similar to the original sentence from "Mencius: Devoted to the Heart", the original sentence is "If you are poor, you will be good to yourself, and if you are good, you will be good to the world".

(3) The third sentence talks about the two attributes of "the Tao": there is no time and space.

(4) Sentence 4 talks about the other two attributes of "the Tao": two columns are given to illustrate this. The "Dao" can operate without qi and summon the wind and rain, and the "Dao" can be transformed into tangible and become birds and beasts.

(5) The fifth sentence talks about the two attributes of "Tao": purity and mixture. Those who have attained the Tao will not be burdened by things and confused by things, and can be accompanied by phoenixes and cranes and whales. It's a figurative sentence.

(6) Sentence 6: Those who have attained the Tao know the attributes of the "Dao": nothingness, emptiness, space, time, others and me, things and me, and they can do things that ordinary people cannot do.

(7) Sentence 7 talks about the relationship between "image" and "heart". This is the theoretical basis of the Dan Dao school.

(8) The eighth sentence is an addition that has to be added. In this passage, the meaning of "knowing" and "attaining enlightenment" is basically the same, and the first seven sentences are all the actions of those who have attained enlightenment, and they are all promising. The true "enlightened one" is one who does nothing and does nothing. So I had to add this sentence "can but not do it".

Said: The power of human beings can take over the heavens and the earth, such as thunder in winter and summer creation. Dead corpses can do, dead wood can bloom. ①

The ghost in the bean, the fishing in the cup, the painting door can be opened, and the earth ghost can speak, all of which are made by pure bowls, so they can turn all things into things. ②

And the bowl is a thing, there is a combination and a dispersion, the reason why I do the bowl, I have not tasted the combination, nor have I tasted the dispersion, there is a combination of life, there is a scatter of death. He has not tasted the people who have not been separated, there is no life and no death, there are guests who come and go, and the mail is always free. ③

Said: There are those who recite blessings, those who have gods, those who have ink characters, and those who change their fingers, all of whom can serve the gods and change all things. However, those who are not sincere are difficult to be confident and easy to tokenize, so if they do this, they know that they are sincere, and there are those who do not wait for them. ④

①②③④

This passage has nothing to do with the Tao or cultivation, it talks about change. Those who recite blessings, those who have gods, those who have ink characters, and those who change fingers, these four types of people "can all serve the gods and bowls and change all things". These four types of people are quasi-saints or saints. But this sentence and the following paragraph: "The saint knows one, the sex is one, and there is no transformation." "Contradictory. "The power of man can conquer the heavens and the earth", which means that people can conquer the heavens?"

Said: One of the people breathes in, travels 400,000 miles a day, and the transformation can be described as fast, but the saint does not remain the same. ①

Said: Qingluanzi is a thousand years old and a thousand years old, and the peach is five and the heart is five. Wouldn't a saint want to be established in the world? The visible number is fearful of the unknowable. ②

Said: All things change, although they are hidden from each other, and the qi is one, but the saint knows one and does not change. ③

Said: The birth of the claw, the length of the hair, the line of glory and guard, there is no instant. Everyone can see it, but they can't see it, and the sage can see it in the sage, but they can't let it go. The saint is willful, so there is no transformation. ④

Said: There are common news in the room, the party in the neighborhood of the door, the mountains and rivers in the suburbs, the different things you see and hear, the likes and dislikes follow, and the competition follows, the gains and losses are successful, and the saints move and stop the precepts. ⑤

Said: For example, the sea changes hundreds of millions of fish, and the water is just one. My and things are so clear, in Dahua, sex is just one. Knowing the husband and nature, no one has no self, no death and no life. ⑥

Said: The principle of the world is to turn yes or wrong, non or yes, grace or hatred, hatred or grace, and it is a saint who is always worried about change. ⑦

He said: The young people should be admired by the teachings of their fathers and brothers, the strong people should be up to the proverbs of their friends, and the old people should be warned of the young and strong. Although Wanhua moves, it can't be misused by me. ⑧

Said: The principle of the world is easy to change, and the heavy is difficult. For example, the wind and clouds must change in a moment, and the nature of gold and jade will last for a long time. Those who are light and enlightened can be transformed with creation without remaining, and those who have not been transformed exist. ⑨

Said: The two young are good together, and they are strong, but they don't know each other when they meet; the two strong are good and they are old, and they don't know each other when they meet. Like the transformation of a sparrow, a pigeon, a dove, there is no past or present. ⑩

①②③④⑤⑥⑦⑧⑨⑩

It is elaborated from various aspects: things have changed, and the saint knows the same, and the nature is one, so there is no transformation.

The demon demon thought: "The saint is too far away from me, and the content of the paragraph has nothing to do with cultivation, so it's over the page." ”
