不眴（玄絹反考聲眴視也從目旬聲也旬音縣從目經文從旬非也有不曉之徒音舜者非也皆不達本文也）。

Not blinking / unwinking (buxuan 不眴: [xuan is pronounced with the] fanqie xuan-juan 玄絹. The Kaosheng says: “Xuan 眴 means looking. Composed of 'eye' (mu 目) with xun 旬 as phonetic.” Xun 旬 is pronounced xian 縣. It takes the 'eye' classifier; in the sūtra text it is written merely as 旬, which is incorrect. Some ignorant people pronounce it shun, which is wrong; none of them understand the original text).
