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。
