Humans, gods, immortals, ghosts, demons, as well as birds, beasts, fish, insects and other animals and plants, together form the universe.
Gods, immortals, ghosts, and demons are also members of the universe. It's just that the living space is different. They coexist with humans, but they don't interfere with each other, and they don't know each other.
Why is everyone afraid of ghosts? When people are in the Yang world, Yang Qi governs life, and they like Yang and hate Yin; ghosts are in the underworld, and Yin Qi governs death, and they like Yin and hate Yang. Therefore, humans are naturally (subconsciously) afraid of ghosts.
In the same way, ghosts are also afraid of people.
In fact, under normal conditions, the two do not interfere with each other, and there is no channel to interfere.
Under special conditions, such as a terminally ill person, whose yang energy is severely damaged, yin energy gradually increases, and the soul flies out of the body, it is possible to see ghosts.
The gods mentioned by the old man Yehe describe the hexagrams that are as accurate as gods.
There is no denying that ancient prediction books have chapters on predicting gods and ghosts, but in real life, they are not very practical. Because no one has ever seen a certain god. For example, if the hexagram shows that it is related to the God of Fire, how can it be confirmed?
To stubbornly believe in a statement that is completely unverifiable is superstition.
