二丈四尺 Threads Matched To The Solar Terms
即變作三條絲線,每條各長二丈四尺,按二十四氣,托於手內,對唐僧道:「這不是我的金線?」近侍宦官在傍道:「長老且休講口,請入宮中診視去來。」即变作三条丝线,每条各长二丈四尺,按二十四气,托于手内,对唐僧道:「这不是我的金线?」近侍宦官在傍道:「长老且休讲口,请入宫中诊视去来。」
逐句解 Line by line
They turned at once into three silk threads, each two zhàng and four chǐ in length, to match the twenty-four breaths of the year. He held them out on his palm and said to the Tang Monk, "Are these not my golden threads?"
長 is cháng here, length — against the zhǎng of 長老 in the line below, the two readings a dozen characters apart. A 丈 is ten 尺, so each thread runs to twenty-four chǐ, and 二十四氣 are the twenty-four solar terms into which the Chinese year is divided. The length is a calendar.
The attending eunuch said from beside them, "Elder, leave off arguing and come into the palace to make your examination."
傍 reads páng in 在傍, at the side, and not the bàng of drawing near, which is what the machine offers. 講口 is to dispute — the eunuch is telling a monk and a monkey to stop bickering.
The measurement is not decoration. Two zhàng four chǐ is twenty-four chǐ, and the twenty-four breaths are the divisions of the solar year, so each thread is a calendar laid out in silk. The correspondence is exact rather than approximate.
That is the answer to the four classics. Tripitaka asked what chapter and verse his disciple had read; the reply is an object built to a cosmological measure, produced from a tail, and it settles the argument because it can be held out on a palm.
And then a eunuch tells them both to be quiet. The chapter's last word on the quarrel comes from a servant with somewhere to be.
