二次念咒 The Second Recitation
唐僧一見，驚下馬來，睡在路傍，更無二話，只是把緊箍兒咒顛倒足足念了二十遍。可憐把個行者頭勒得似個亞腰兒葫蘆，十分疼痛難忍，滾將來哀告道：「師父莫念了，有甚話說了罷。」唐僧一见，惊下马来，睡在路傍，更无二话，只是把紧箍儿咒颠倒足足念了二十遍。可怜把个行者头勒得似个亚腰儿葫芦，十分疼痛难忍，滚将来哀告道：「师父莫念了，有甚话说了罢。」
逐句解 Line by line
At the sight of it the Tang Monk toppled from his horse and lay in the road, and without another word he took the Tight-Fillet Spell and recited it, over and over, a full twenty times.
驚下馬來 (jīng xià mǎ lái) "fell from the horse in fright." 緊箍兒咒 (jǐn gū er zhòu) "the Tight-Fillet Spell," the suffix 兒 (er); 顛倒足足念了二十遍 (diān dào zú zú niàn le èr shí biàn) "recited it fully twenty times over," 顛倒 (diān dào) here "again and again, the whole thing through" (倒 (dào)). Twenty recitations — the elder makes good, and more, on his earlier threat, the second punishment far exceeding the first.
Pitiable! — Pilgrim's head was squeezed till it looked like a pinch-waisted gourd, the pain past all bearing; and rolling over to plead, he cried, "Master, stop reciting! If you have something to say, then say it, and be done."
頭勒得似個亞腰兒葫蘆 "his head bound tight till it resembled a wasp-waisted gourd" — 勒得 (lēi de) "bound so that" (the complement 得 (de)), and the vivid figure of the 亞腰兒葫蘆, a gourd pinched in at the middle, for the constricted skull. 滾將來 (gǔn jiāng lái) "rolling over," 將 (jiāng). 有甚話 (yǒu shén huà) "what [you] have to say," 甚 (shén). The grotesque image measures the fillet's cruelty — and Wukong's helplessness before it.
The second recitation escalates the first with deliberate excess: twenty times over, 顛倒足足, "again and again, the whole thing through." The elder who once threatened twenty recitations for further "evil" now delivers them in full — his mercy, once so easily moved to pardon, hardening under Bajie's influence into a readier cruelty. The cycle is repeating, but the terms are worsening.
The narrator's grotesque figure — the Great Sage's head "squeezed till it looked like a pinch-waisted gourd" — makes the fillet's power viscerally physical. The one being who overturned Heaven is reduced to rolling in the road, begging for the pain to stop. Each turn of this scene drives home the chapter's central inversion: absolute strength made helpless before the spell of a deceived and gentle master.
