Are there really six divisions of the wheel of karma of Buddhism in the world? What examples can prove it? I hope some experts can solve the problem!

Many people don't believe in reincarnation because they can't see the complete trajectory of life. But not seeing it doesn't mean it doesn't exist. Let me make an analogy. We can get a general understanding of the cycle of life:

Take the process of caterpillar, pupa and butterfly as an example. Everyone knows that caterpillars will turn into pupae and then break into butterflies. In fact, only the same life changed its life form. However, please note that even if the pupa and the pupa chat, they don't believe that they have been changed by the caterpillar, because this life has not changed, but the memory of the caterpillar has been cut off (it has not been lost, but exists in its subconscious and has been discovered). Of course, they don't believe that their past lives were caterpillars, and they don't believe that their afterlife will become beautiful butterflies, because from their point of view, the memory of every life is over, but as people who are one level higher than them, they can clearly see it. This is the mystery that Buddhism discovered that everything in the world is "divided into life and death": life is always going on. Every life is the same life in reincarnation, but the parties don't understand or believe it. Therefore, there is a saying of "three-life karma", that is, "the afterlife of past lives", which is changed to "past, present and future" in modern words. If this caterpillar understands the cause and effect of the third world, it will eat leaves desperately and try to avoid natural enemies. In this case, if you become a pupa, you will naturally be fatter than other pupae. Then once it breaks into a butterfly, it will naturally be bigger, stronger and fly farther than other butterflies. Buddhism uses "if you want to know today, your previous life is;" If you want to know the afterlife, it is appropriate to describe this process. In the same way, if there are creatures more advanced than us, they can easily see our past lives and afterlife (we can't see and don't believe it, the principle is the same as pupa).

Not everyone can see the life cycle, because our ordinary people's body and mind are confined to the three-dimensional space of our lives, while Buddhists can see the six divisions in the wheel of karma. Just because Buddhist practitioners have crossed the three-dimensional space of ordinary people, the life cycle does not have to be seen by religious people, nor is it a Buddhist patent belief. Anyone who can go deep into high-rise space can find that people have past lives and life cycles. Under hypnosis, many normal people can find their past lives, so the life cycle is. So what's the point of knowing the cycle of life? My understanding is that once you know the law of life cycle, you know the meaning of life, you know the meaning of life, and you know what you should do. How should you spend your life?
