He tends to disturb harmony and get people upset. And just like wind, he is there one minute and gone the next. I was 'hit' by this wind the other day. He popped into my work area, spoke to me for no more than 1 minute and then was gone. In one minute I went from centered and focused to angry, resentful and irritable.
Wind is an interesting thing.
It is relatively insubstantial, but arouses and stirs up the qi, which in turn can cause all kinds of other processes to get out of whack. I can see how wind can be the root of so many problems. It's insubstantial nature is hard to guard against. It slips in through the cracks. Because it does not have much substance it seems weak, but it's tricky, because it's effect is strong.
