Art doors in China have been divided into two types since ancient times: the Xuanmen and the Daomen? So what's the difference between them?

Xuanmen mystery, Lao Tzu's morality is mysterious.

Xuanzhe is the father of nature and the bulk of all things.

An ontological proposition put forward by Ge Hong. "Xuan" is the core concept of Ge Hong's Taoist philosophy ontology. Ge Hong put forward the proposition that "Xuan is the ancestor of nature and everything is different" in Chang Xuan, the first article of Bao Puzi. Everything is different. Ge Hong thinks that "Xuan" is omnipresent and mysterious. Subtle, far-reaching and endless. "Its far cover nine clouds, its wide cover octagon. The light on the sun and the moon is the opposite of flying. ..... Stone can't be stronger than it, and Zhan Lou can't wait for it to be soft. Square but not moment, round but not straight. Don't look, don't chase. " ("Bao Pu Zi Chang Xuan") Such a profound and subtle thing, which comes and goes without a trace, is full of mystery. It can make the sky high, the land low, the clouds flowing and the rain pouring, and it can give birth to the breath of Yuan Yi. Zhu Fan's two instruments of heaven and earth are the beginning of all things. In a word, "Xuan" is the mother of all things in the world and the total source of the universe. Ge Honghu combined Taoism with metaphysics. "Tao is also a person, so the Bai family is educated, and there are hundreds of kinds of students, and those who are easy to discuss are also brewed." (Bao Puzi Ming Ben) Ge Hong believes that it is impossible to simply judge the existence of Taoism or metaphysics. "Without it, the impact is still far-reaching; On its existence, everything is still innocent. " Tao or metaphysics (the Tao meaning of Bao Puzi) is not there, nor is it there. "Because of omen, there is nothing because of silence" (Song of Eternal Sorrow by Bao Puzi), but in the end, there are "born out of nothing" and "Palace of Nowhere" (Zhi Li by Bao Puzi), and nothing is dominant. Ge Hong established the philosophical system of Taoist idealism on the basis of this proposition.

The first chapter of Tao Te Ching Lao Tzu is the door to all good things.
