After all, life has many characteristics and is evolving, but there are only two directions; one is the direction of goodness and light, and the other is the direction of evil and darkness. After the extreme of the direction of goodness and light is the eternal paradise of happiness, which is an indescribable state. And after the extreme of the evil dark direction is hell, which is under the three universes of the dark world. What are the three universes in the dark world? One is the universe of inner demons, one is the universe of physical demons, and the other is the sky of darkness. What is the inner demon universe? What is the demonic universe? It is said that there are two forces in the void, one good and one evil. Good and evil can be divided into internal and external aspects. What does the so-called internal and external refer to? Internal is spiritual power. The external force is tangible and material, but this external material force must also be based on the spirit. When the inner power and nature of evil evolve to the ultimate level, it is called the inner demon. When the external nature and power evolve to the ultimate level, it is called the physical demon, that is, the external demon. Positive power also has internal and external components. The internal ultimate is called the Heart of Light, and the external ultimate is called the God of War. Positive inner power is also mainly spiritual power, and external power is also mainly tangible and material power. However, these two internal and external forces are interdependent and cannot function independently. Sometimes distinctions are made between inside and outside just because of the relationship between strength and weakness.
