B

A wise man was walking from one town to another with a few of his followers, and they happened to pass a lake. So they stopped there to rest for a while, and the wise man said to one of his followers, “Could you please get me some water from the lake ?”

One of the followers walked to the lake. Some people were washing clothes in the water, and right at that moment, several carts started crossing the lake. As a result, the water became very muddy(浑浊的).

Then he went back, and told the wise man that the water was very muddy and not fit to drink. After they had rested for about half an hour. the wise man again asked the same follower to go back to the lake and get him some water to drink. And the follower went to the lake. This time he found that all the mud had settled (沉淀)to the bottom. the water was very clear and looked fit to drink. So he filled his water bottle and took it to the wise man.

The wise man took the water bottle and drank, then looked up at the follower. “ See what you did to make the water clean?” he said. “you let it be for a while and the mud settled down on its own, so that you could get some clear drinking water. Your mind can also be like that lake when it is disturbed (使恼怒)by something. If you just let it be and give it a little time, it will most likely settle down on its own without you having to put in any effort at all to calm it.”
