Water vapor, that gas, refers to the state of gas.
In metaphysics, the so-called "qi" is actually a state. This state is not the state of water, but the state of the spirit of all things. For example, when we look at Feng Shui, this "qi" is the core of Feng Shui. Feng shui talks about weather. This weather is not the weather in the "weather report", but the weather of the harmony of yin, yang and five elements. Our ancient Taoists pay attention to "aura". In fact, this aura is the manifestation of the functions of all things in the world. Foreign countries talk about magnetic fields, and this concept is somewhat similar, because science has proven that everything on the earth has magnetism, but the size is different. This magnetism is a function.
In addition, people have the eight functions of earth, water, fire, wind, and space, and the wind can also be said to be Qi. It’s a person’s Qi. But this pulse is different from the anatomical pulse.
For more details, I hope LZ can check some information on his own. I only know so much at the end of my studies.
Wish you good luck and good luck
