元神詰風 The Primal Spirit Questions the Wind
好大聖,拔下一根毫毛,吹口仙氣,叫:「變!」就變作一個假行者,立在唐僧手下。他的真身出了元神,趕到半空中,高叫:「那司風的是那個?」慌得那風婆婆捻住布袋,巽二郎劄住口繩,上前施禮。好大圣,拔下一根毫毛,吹口仙气,叫:「变!」就变作一个假行者,立在唐僧手下。他的真身出了元神,赶到半空中,高叫:「那司风的是那个?」慌得那风婆婆捻住布袋,巽二郎札住口绳,上前施礼。
逐句解 Line by line
Good Great Sage! He plucked out a strand of hair, blew on it a breath of immortal air, and cried, “Change!”
拔下一根毫毛: the level tone of 根 keeps 一 at yì. 吹口仙氣 "blew a puff of immortal breath" -- the standard mechanism of his transformations, and by this point in the novel as familiar as a conjuror's flourish.
It changed at once into a false Pilgrim, standing there below the Tang Monk.
變作一個假行者: 行 = xíng; the falling tone of 個 pulls 一 to yí. A stand-in left below, so that four figures are still visible from the tower while only three are real.
His true body sent forth its primal spirit, rushed up into the mid-air, and cried aloud, “That one in charge of the wind — which of you is it?”
半空中: 中 = zhōng. 元神 "the primal spirit," the part of a Daoist adept that can be sent out of the body and travel on its own -- so the trick he is using against the Daoists is a Daoist one. The line then does the two-reading turn again: 那司風的 has 那 = nà, pointing at whoever governs the wind, and 是那個 has the same character as nǎ, asking which one it is.
In alarm, Granny Wind pinched shut her cloth bag, Xun the Second knotted fast the mouth-cord, and both came forward to make their bows.
慌得: 得 = de. 那風婆婆: 那 = nà. 巽二郎 is Xun the Second, a wind spirit named for 巽, the trigram of wind. 劄住口繩 "to knot the mouth-cord fast" -- shutting the wind sack. The character 劄 reads zhá here, as in the sense of pinning or fastening.
Now we learn how it is done, and the method is worth admiring. He leaves a hair-double standing beside his master so the court sees four monks, and sends his own spirit up into the air to find out who is running the weather.
What he finds is not a rite to be broken but two frightened officials. Granny Wind pinches her bag shut and Xun the Second knots the cord, and neither of them argues. The Daoist commands by paperwork; the Great Sage commands because they know exactly who he is and what he did the last time heaven annoyed him.
There is a nice irony in the mechanism, too. Sending the spirit out of the body is a Daoist technique. He beats the Daoists with their own equipment, and it does not occur to him that this is worth remarking on.
