It means that blind people focus their vision on their ears, so their hearing is sensitive; Deaf people focus their hearing on their eyes, so their eyesight is extraordinary. If you can cut off the side that makes you convenient, so as to collect your mind and achieve sincere concentration, it is ten times better than learning from the teacher; If you can rethink, think repeatedly day and night, and achieve concentration, it is better than learning from the teacher for ten thousand times.
Normal people are neither deaf nor deaf. However, when doing something, if you can work hard, listen but not listen, turn a blind eye and have no side drive, then things will be easy and work will be easy. All knowledge and undertakings are easy to succeed if they can be thoroughly cultivated for a long time, and it is difficult to succeed if they are half-hearted.

Original text: "The way to watch the sky, the trip to watch the sky, is tired. There are five thieves in the sky, and those who see them are prosperous. The five thieves do it with their hearts, and the sky does it. The universe cares about hands and everything is born. "
Looking at the trajectory of heaven and doing the mission entrusted by heaven, (the mystery of everything) will be exhausted. Jin Mu has fire, water and earth (the five elements coexist), and people who see it will prosper. The five elements are experienced in the heart and are in harmony with heaven. In this way, although the universe is big, it is still in the palm of your hand (heaven and earth in the palm of your hand), ever-changing and not outside (the human body is a small world). "
Original text: "Nature, people are also; People's hearts are full of opportunities. The way to establish heaven lies in fixing people. "
Nature is the foundation of human beings, but human heart is deceitful. Therefore, it is necessary to settle people's hearts with heaven. "
