The speaker is talking about how they can track the wind by observing what it blows. They mention that the wind comes from somewhere and moves very fast. They also mention that nobody knows where the wind comes from, but they can tell where it goes. And then when I found it, whatever it blew, I should know that the wind had been going there too. It's flying from somewhere as fast as it can. I couldn't keep up with it if it ran. No one can tell me. Nobody knows where the wind comes from, where the wind goes. So then I could tell him where the wind goes, but where the wind comes from, nobody knows.
