Sometimes rebirth doesn't have to be a death here, a soul out of the body to another person, and then the process of opening up a life. Maybe it's an event in your life that you will never forget; Maybe it's a moment of realizations that come from work; Or maybe it's just because of the death of a loved one, so that you start to completely change your life after getting to know yourself again. Probably this is a complete rebirth of a person. Phoenix's Nirvana ...... The most important thing in life should be the sublimation of the spiritual level, not just the soul re-changing its body. The young master of a feudal slave family, because of a dream, dreamed of himself in another world, where the world and his own world have completely different worldviews, outlooks on life, and values. And his righteousness, kindness, and courage in that world made him slowly begin to change himself and change the changes of an era. Even at some point, he can talk to himself in a distant world in his dreams, two different time and space selves, influencing each other and spurring each other.
