The six divisions in the wheel of karma are natural laws, just like mathematical axioms. That's it. No one invented it. All the religions in the world have discovered the existence of Six Daoism more or less, but they all know it but don't know why. Only when the Buddha became a monk, understood the truth, and explained to his disciples in detail the cause and effect of the existence and reincarnation of the six doctrines, could the six divisions in the wheel of karma theory be truly and completely known to the world.
Six ways: Heaven, Humanity, Asura, Beast, Hungry Ghost and Hell. The first three are three good ways, and the last three are three evil ways. All living beings are drawn by their own good and evil all their lives, and they are reincarnated in the six paths. The only way to think of reincarnation is to study Buddhism. ?
