首楞嚴義疏注經 3.410

3.410

破面生也。初二句牒，從彼下四句破。被拂之人面若生風，應合順吹，汝當受拂，汝自整衣，不干風出，云何其風反吹彼面？

This refutes arising from the face. The first two lines restate the premise, and the four lines beginning with 'from that' refute it. If the face of the person who is brushed produced wind, it should blow straightforwardly and you should receive the wafting; since you yourself straighten your robe, it has nothing to do with wind coming forth, so why would that wind instead blow against that person's face?
