眼脈（上五限反釋名云眼限也謂視物有限也從目限聲下莫獲反切韻血脈也釋名云脈幕也謂絡幕一體也說文從肉派省聲經文作脉俗字也）。

Eye veins (眼脈: the first [character] is *yan*, fanqie 五限. The Shiming says: 'The eye (眼) means a boundary (限), meaning there is a boundary to seeing things.' Derived from the eye radical 目 with 限 as phonetic. The second [character] is *mai*, fanqie 莫獲. The Qieyun says: 'Blood vessels.' The Shiming says: 'Vessel (脈) means curtain (幕), meaning enveloping the whole body.' The Shuowen jiezi says it is derived from the flesh radical 肉 with the phonetic 派 abbreviated. In the sūtra text it is written as 脉, which is a vulgar variant).
