it is your mind that is moving

A Zen story describes three men observing a flag fluttering in the breeze:

One man says, “The wind is moving the flag.”

The second man says, “No, the flag is moving the wind.”

The third man says, “You are both wrong; it is your mind that is moving.”

三个人正在观察一面旗帜在微风中飘扬：一个人说，旗帜在移动。

第二个人说，风在动。

第三个人说，你们都错了，是你们的心在动。
