Don't underestimate the phrase "the origin is empty". These four words can sum up all the laws of life and death in the world.
The origin is that all methods of birth and death are born of karma, karma gathers to produce, and karma disperses to destroy. So there is no such thing as eternal life.
Sexual emptiness means that since all birth and death methods are born of karma, there is no self that will never disappear.
Life or death, these eight words are to further describe the origin of emptiness, flowers and plants die or glory, life or life or death, everything is impermanent.
The last sentence "What kind of life is this?" Asking us: How will you spend your life? The reason why Buddhism talks about the emptiness of origin is not to make you pessimistic and disappointed, but to make you understand the truth of the law of birth and death of cause and effect, so that you will not return to clinging to money, beauty, high officials and so on, because these are all like floating clouds and unreal. At this point, Buddhism tells you that the law of life and death in the world is not worth pursuing, and what we should pursue is the state of nirvana that is immortal.
