"Tao" is a term used by the Chinese nation to understand nature, which means the trajectory or trajectory of everything, and it can also be said that it is the change and movement of things.
Everything is not the thing itself, the sun and the moon are self-evident, the stars are self-ordered, animals are self-made, the wind is self-driven, water flows by itself, plants are self-planted, breathing does not breathe, the heartbeat does not beat, and so on.
Because all things are not things, they all follow something without exception. It is the root of change, immortal, intangible, without image, without beginning or end, and all-encompassing. Nothing more than big, nothing more than small, changing with time and never changing. I was unknown at the beginning, and I don't know whose son it was. Laozi has a strong name: "Tao."
Taoism believes that Tao is the old gentleman on the throne. In old Xiangzi's place, "Tao" was dispersed and condensed into "the old gentleman on the throne".
"Too old gentleman" is the ontology (Tao body) of the avenue, and "innate touch" is the function (Tao use) of the avenue.
Chapter 17 of Tao Te Ching: The "Tai Shang Lao Jun" didn't know about it. Chapter 25 of Tao Te Ching: Things are miscellaneous (Tao body), and Tao is things, among which there are essence, among which there is faith (too old gentleman). ..... Independent and unchangeable, free and without danger (innate).
Grand Master Zhuangzi: Fu Tao, love and faith (Tao style), inaction and invisibility (Tao usage), can be passed on but not received, can be obtained but not seen; Since its roots, it has been preserved since ancient times; Ghosts were born; Before tai chi, it was not high, but below the six poles, not deep; Born, not long, longer than ancient, not old.
