There is three monks discussing about a red flag flapping in the falling rain and storm.
“It’s the flag that is really moving,” the first one said.
“No, I think the flag that is moving,” the second argued.
“No, I think your mind is moving” the third discuss
Three of them argue each other like a storm.
A abbot, who coincident walking by, hear their debate and spike them. “Neither the flag nor the wind nor mind is moving,” he said,
“Your mouth are moving.”
