The first sentence is that all law is empty, and the origin is empty. We can't go back to the past, even for a second, and we can't reach the future. The present will become the past again, so what people actually exist is only the continuation of the present, so this sentence reveals the truth of the life universe, but it is hard to accept that everything is true. The second sentence is, secular desires, give up people, can see themselves, people's eyes can't see things. According to the actual anatomy, people's eyes only send out a signal, and the feeling they can see is the true face of people. The third sentence is about what people should do. There are changes at any time. It's not eternal. It's all fake. So do you still need to care about persistence? Everything just goes with the flow, doing nothing and doing everything. Although I am doing it, I am not led by my heart, just like a wild goose crossing a lake without taking a picture. The last sentence is about everything in life, and it is also a summary of the previous three sentences. All the laws of the universe are in the first three sentences. The first sentence is aspect, the second sentence is phase, the third sentence is use, and the fourth sentence is a summary of the previous words, including the use of aspect.
