All rivers flow again and again to the same place. They all flow to the sea, but the sea never becomes full.
The wind blows to the south, and the wind blows to the north. The wind blows around and around. Then it turns and blows back to the place it began.
Words cannot fully explain things, but people continue speaking. Words come again and again to our ears, but our ears don’t become full. And our eyes don’t become full of what we see.
