階前得珪 The Tablet on the Step
行者果然開門,一齊看處,只見星月光中,階簷上,真個放著一柄金廂白玉珪。八戒近前拿起道:「哥哥,這是甚麼東西?」行者道:「這是國王手中執的寶貝,名喚玉珪。師父啊,既有此物,想此事是真。明日拿妖,全都在老孫身上。只是要你三樁兒造化低哩。」行者果然开门,一齐看处,只见星月光中,阶簷上,真个放着一柄金厢白玉珪。八戒近前拿起道:「哥哥,这是甚么东西?」行者道:「这是国王手中执的宝贝,名唤玉珪。师父啊,既有此物,想此事是真。明日拿妖,全都在老孙身上。只是要你三桩儿造化低哩。」
逐句解 Line by line
Pilgrim did indeed open the door, and as they looked together, there in the light of stars and moon, upon the step beneath the eaves, truly there lay a gold-mounted white-jade tablet.
The proof-object crosses from the dream into the world, and the staging is careful — starlight, the step under the eaves, and 真個, "truly," doing the work of a held breath. 看處 is "as they looked"; 星月光中 takes the locative zhōng; 放著 has 著 as zhe, lying there.
Bajie stepped up and took it, saying, “Elder brother, what thing is this?”
Bajie picks it up and has no idea what it is, which is exactly the right question from exactly the right character. 甚麼 has 甚 as shén.
Pilgrim said, “This is the treasure the king held in his hand, called the jade tablet.
Wukong knows. Note that this is the one place in the chapter where the object is called simply 玉珪 rather than 白玉珪 — ten times elsewhere the white jade is spelled out. 手中 takes the locative zhōng.
Master, since we have this object, I think the matter must be true.
The argument is settled by the object, not by reasoning: the thing is here, so the story is true.
Tomorrow’s catching of the fiend rests wholly upon old Sun.
He takes the whole job on himself, which is the pattern of every arc he appears in. 全都 has 都 as dōu, wholly.
Only, it will call for three turns of low luck on your part.”
And immediately spoils the solemnity. 三樁兒 is "three items," with 兒 as the light er ending; 造化低 is low luck, poor fortune — he is telling Bajie that tomorrow is going to be a bad day, and enjoying it.
The dream is confirmed by daylight evidence: the jade tablet lying on the step in the starlight. This is how recognition-tokens work in romance — the object appears, and the argument stops. Even Bajie cannot wave it away, though he can still fail to recognise it.
Wukong shoulders the entire task, as he always does, and then punctures his own gravity by promising Bajie "three turns of low luck" tomorrow. The joke plants the next passage and keeps the chapter's rhythm going: every time the story reaches for solemnity, one of the disciples pulls it back down.
