Not the wind, not the flag

Two monks argue about a banner. A stranger settles it in one line, and the abbot asks to be his student.

Chapter 04 of 12 in The masters were funny

Two monks are watching a banner move in the wind and arguing. One says the flag is moving. The other says the wind is moving. They go back and forth in the way that people do when the argument has stopped being about the flag.

A stranger standing nearby says it is not the wind that moves, and not the flag. Your mind is moving.

The stranger was Huineng, still a layman at that point, and the later editions of the Platform Sutra have the abbot recognising what he is a moment later. The line has survived thirteen hundred years mostly because it is a great put down.

Read fast, it sounds like the standard idealist claim that it is all in your head and the flag is not real. Huineng does not say the flag is imaginary. He is answering two men who have made an argument out of a distinction they invented, and he is pointing at where the distinction is being made.

What I take from it is smaller and more testable than a theory about matter. Through a day, much of what looks like a fact about the world is a movement in the observer. The order is late. The message is rude. Each of those has a fact in it and a motion in me, and I report the whole package as news from outside.

This is also the most abusable line in Zen. Said to someone whose problem is real, your mind is moving is a way of telling them their trouble is their own fault, and spiritual people use it like that. The monks in the story were arguing about a piece of cloth. They were not hungry or being cheated.

So I keep it for the flag sized cases, which turn out to be most of my week.
