Originally, "monster" could not be regarded as an independent category among monsters. He just emphasizes strangeness and strangeness, and is often called a monster. But then gradually derived a real monster, such as Huang Paoguai in The Journey to the West. He is one of the 28 stars in the sky. The Kuimu Wolf descended to earth to do evil, and was called Huang Paoguai because of his strange appearance. So most monsters are strange, even scary, most of them are noble or unknown, harmful to people, and can move around day and night.
In ancient times, "magic" was regarded as "grinding", and Liang Wudi Xiaoyan, the founder of Nanliang regime, turned "stone" into "ghost". Magic is the abbreviation of "magic". Buddhism calls all psychological activities that disturb the body and mind, destroy good deeds and hinder practice magic. Only with high mana and harm to human beings can it be called magic. Demons are far more powerful than ordinary demons. The difference between the two is that demons may have been descended into evil ways by immortals and gods, rather than directly cultivated by animals and plants.
Ghosts, commonly known as ghosts and gods, are the soul of life among the three souls after death. Ghosts are pure yin in Taoist records, so they have a little "super power", but they are too weak to even be called spells. Most of them can only scare people and do no substantial harm to people. Ghosts are mainly formed by the soul after death, and usually can only move in the underworld. There are also some individuals who will return to death if secular things are not over. Of course, the legendary ghost is forbidden. Once you find out where you have to pay the price.
Ghosts generally have three ways out. First, reincarnate as human or animal; One is suffering in the hell set by the underworld; There is also a less common phenomenon, which is becoming a god. Generally speaking, the deceased people who do many good deeds, or cultivate monks, or be guided by experts, or be blocked, have a great influence. Because they may not be able to cultivate immortality, they may not be able to cultivate immortality successfully, so they have no chance to become immortals. They may be chosen by heaven to become gods and hold certain positions after death.
"Essence" refers to the state of plants or nonliving bodies that have not become demons or immortals in the process of cultivation after long-term cultivation, but have certain mana, such as ginseng essence and tree essence. Mana is slightly less than demon, but also kinder than demon. Likes to confuse people, does no harm to people, and can be active during the day and night.
"Spirit" refers to the existence that the living or non-living body absorbs the essence of heaven, earth, sun and moon and produces self-consciousness, but has not yet practiced. For example, in the Monkey King, Heaven and Earth were born without father and mother. "Spirit" also refers to non-human beings who are born with spirituality. As recorded in the Book of Rites, "Lin, phoenix, turtle and dragon are collectively called the Four Spirits. 」
