Chapter 56 of Tao Te Ching: Those who know speak, and those who speak know. Plug the switch and close the door; Frustrate their spirit and resolve their disputes; Its light, its dust; It means Xuan Tong. So, you can't get close and you can't get it. If you can't get it, you can't get it, and it hurts; If you can't get it, it's expensive. If you can't get it, it's cheap, so it's expensive for the world.
Interpretation: because smart people can't talk big, people who talk big have no wisdom; Block the hole of lust and close the heart of desire; Cut off the edge and get rid of troubles; Contain your own glory and confuse yourself and the world;
This is the so-called deep and subtle Xuan Tong. So it is impossible to be close to him, and it is impossible to be alienated from him; It is impossible for him to gain or lose; It is impossible to make him noble or humble, so he is valued by the whole world.
Extended data:
The rich cultural heritage of the Chinese nation is far beyond our understanding and imagination. Moreover, our heritage is alive, unlike the pyramids in ancient Egypt and the temples in ancient Greece, which makes people marvel at the incredible creativity of the ancients;
But today, our overall scientific and technological strength is certainly much stronger than that of the ancients, whose wisdom is condensed in material civilization. The biggest role is to warn people today, especially modern people who think they have mastered the scientific and technological means to transform nature, not to be too conceited.
The thoughts, philosophy and wisdom of the ancients condensed in China's writings not only make the Chinese nation the only ancient nation with thousands of years of history and continuous blood, but also play a correct leading role in the construction of the future world;
It is a great gospel for building a new world, because these ideas, philosophies and wisdom have stood the test of thousands of years of history and are proved by a lot of positive and negative experiences and lessons. As long as we dig a little bit of this treasure, China and even the world will benefit a lot.
