I wondered how many billions, if not hundreds of billions, of these stones were in the river alone. I can't see the flow from the riverbank, but I can see the stones continuing all the way to the mountains across the river. It is a matter of extracting some of the stones from the large amount of stones on the riverbank. And that there are many stones not to choose. If you ask me why I chose them, I could give you some reason. But the words don't seem to be true. There are stones that I choose, and I am certainly picking them up with my own hands. I am just looking at what I am doing.
