What they say is just nonsense that they don't pretend to understand. What I'm talking about here is the real root. If you don't believe me, you can check all kinds of ancient books: in short, God, Immortal and Buddha are the highest cultivation realms of mortals, Taoists and Monks respectively. God is the highest realm of human cultivation. Remember, ordinary people here refer to non-religious laymen who are neither monks nor Taoists, because they have no patriarchal clan system to follow, so the so-called cultivation of ordinary people refers to all kinds of behaviors and achievements in the world. After death, if you get an official position in the heavenly palace, you will become a god. Therefore, most people in the Heavenly Palace are gods, such as Erlang God, God of Wealth, Door God, King Tota, Nezha and Four Kings. Immortals are the highest realm of Taoist cultivation, that is, according to Taoism, they will eventually become immortals, such as the first Buddha, Bodhi Bodhi Bodhi Bodhi Bodhi Bodhi Bodhi Bodhi Bodhi Bodhi Bodhi Bodhi Immortals and so on. They are all immortals, but because Taoist precepts are not as strict as Buddhism, the relationship between Taoist and mortal is relatively close, so the relationship between immortals and immortals is also relatively close. For example, there are immortals in the Heavenly Palace who assist the Jade Emperor, such as Tailaojun and Taibai Venus. Buddhism is the highest realm of monk practice, that is, practicing according to Buddha and eventually becoming a Buddha.
By the way, the difference between ghosts, demons and demons is attached: ghosts refer to people who die and fail to reach any one of the gods, immortals and Buddhas, and will inevitably become ghosts (remember, ghosts are not all terrible, but only a necessary stage); Magic means that non-monks and non-Taoists practice witchcraft and evil methods to reach the highest level (this level is the six divisions in the wheel of eliminating karma, reaching the realm of immortality and immortality), that is, magic; Demon refers to the highest cultivation realm of non-human objects.
