For doctors, death is actually the inevitable result of a disease or injury. From a medical point of view, any death is caused by disease or injury. Even those elderly people who died quietly in their sleep must have some The cause of a disease can be explained. Therefore, the understanding of life and cause and effect in medicine has become very mechanical, simple, and even crude. If you have a fever, lower your body temperature. If you have stomach cancer, remove a part of the broken stomach , If the blood pressure is too high, dilate the blood vessels, if the heartbeat has no strength, use a pacemaker, if the mouth cannot breathe, insert a tube in the trachea... So I often reflect on myself, although this explanation sounds It sounds very reasonable and intuitive, but can it really explain the cause and effect of life? The Buddha said: Fear cause and effect and don't hate death!
