Once upon a time, a father and his son were walking from one town     1     another. While they were traveling, they happened to pass by a river. They were tired and stopped there to     2    . Then the father asked his son to get him some     3     from the river.

Then the son walked to the riverside     4     he saw some women washing clothes there. Right at that moment, a bullock cart (牛车) started crossing the river. As a result, the water became very     5    . “I mustn’t take the dirty water to my father,” he thought. So he came back and said, “Look, Father. A bullock cart     6    crossing the river now, so the water is dirty and it can’t be drunk.” Father said nothing.

After a while, the son was asked to get some water     7     by his father. The water was still dirty, but he didn’t go back. He thought, “My father is so thirsty. I must take back     8     water this time, even though it will take me a long time.” Then he sat there, waiting     9     the water was clean. He collected some in a bowl and took it back.

“Oh, you are back at last. I have waited for you for almost half an hour,” Father said. After     10     the water, he looked up at his son and said, “Now, think about what made the water clean. You let it be and the water became clean on its own. It is also the same with your mind. When it is disturbed (打扰), just let it be, and it will calm down on its own.”
