My life is limited, but my knowledge is infinite. It is really dangerous to pursue infinite knowledge with limited life! There is danger, but also the persistent pursuit of knowledge, then there is nothing but danger. You don't need fame to do good, and you don't need punishment to do bad. With the aim of following the nihility of nature, you can protect your life, preserve your nature, save the opportunity of new life and enjoy all your years.

My master is Liang Zainiu. Hands touching the ground, shoulders leaning on the ground, feet treading on the ground, knees touching the ground, there is no rhythm when entering the knife: it conforms to the rhythm of Sanglin (in Tang) dance music and Jing Shou (in Yao) music.

Liang said, "Hey, good! How can technology (you know cows) be so superb? "

My mechanic put down his knife and replied, "I am pursuing Tao (a function word with no specific meaning, which can be translated into the laws of nature), which has surpassed the general technology." At first, when I slaughtered the cow, I saw a complete cow in my eyes; Three years later, I have never seen a complete cow (meaning: I only saw a little cow, that is, I only saw how to solve it). Now, I am in contact with cows by spirit, not by eyes. My senses stopped, but my spirit was moving. According to the natural physiological structure of cattle, cut into the gap between the bones and muscles of cattle and eat along the gap between joints. According to the original structure of the cow, the place where the tendons are connected and the bones are combined, the knife has never touched it, let alone the big bone! Skilled chefs change a knife every year and cut it with a knife (just like we cut a rope with a knife); Skilled chefs have to change a knife every month, and the knife is broken by cutting bones (because they don't know how to cut, cutting bones is easy to break). Now, my knife has been used for 19 years, killing thousands of cows, but the blade is as sharp as if it had just been sharpened on a grindstone. There are gaps in the joints of cattle and the blade is very thin; If you insert a thin blade into a cracked bone joint, there must be room for the blade to operate! Therefore, for 19 years, the blade was only ground from the grindstone. Even so, whenever I meet a place where bones and muscles are intertwined, I see that it is difficult to cut, so I carefully raise my vigilance, focus on one point, slow down, move my knife very lightly, and with a sigh, the bones and meat of the cow are suddenly untied, just like mud scattered on the ground. I stood up with a knife in my hand and looked around. I am carefree and satisfied, then I clean it and collect it. "

Liang said, "Good! After listening to my words, I understand the truth of keeping in good health.
