淨瓶與金鋼琢 The Vase and the Diamond Bangle
菩薩開口對老君說：「貧僧所舉二郎神如何？果有神通，已把那大聖圍困，只是未得擒拿。我如今助他一功，決拿住他也。」老君道：「菩薩將甚兵器？怎麼助他？」菩薩道：「我將那淨瓶楊柳拋下去，打那猴頭，即不能打死，也打個一跌，教二郎小聖好去拿他。」老君道：「你這瓶是個磁器，能打著他便好，如打不著他的頭，或撞著他的鐵棒，卻不打碎了？你且莫動手，等我老君助他一功。」菩薩道：「你有甚麼兵器？」老君道：「有，有，有。」捋起衣袖，左膊上取下一個圈子，說道：「這件兵器，乃錕鋼摶煉的，被我將還丹點成，養就一身靈氣，善能變化，水火不侵，又能套諸物。一名『金鋼琢』，又名『金鋼套』。當年過函關，化胡為佛，甚是虧他。早晚最可防身。等我丟下去打他一下。」菩萨开口对老君说：「贫僧所举二郎神如何？果有神通，已把那大圣围困，只是未得擒拿。我如今助他一功，决拿住他也。」老君道：「菩萨将甚兵器？怎么助他？」菩萨道：「我将那净瓶杨柳抛下去，打那猴头，即不能打死，也打个一跌，教二郎小圣好去拿他。」老君道：「你这瓶是个磁器，能打著他便好，如打不著他的头，或撞著他的铁棒，却不打碎了？你且莫动手，等我老君助他一功。」菩萨道：「你有甚么兵器？」老君道：「有，有，有。」捋起衣袖，左膊上取下一个圈子，说道：「这件兵器，乃锟钢抟炼的，被我将还丹点成，养就一身灵气，善能变化，水火不侵，又能套诸物。一名『金钢琢』，又名『金钢套』。当年过函关，化胡为佛，甚是亏他。早晚最可防身。等我丢下去打他一下。」
逐句解 Line by line
The Bodhisattva opened her mouth and said to Lord Lao, "How is this Erlang I recommended? He has real divine power, has hemmed the Great Sage in, only he hasn't yet managed the capture.
所舉 ("the one [I] recommended") — it was Guanyin who, in an earlier passage, proposed Erlang for the task; she now claims a measure of credit, with a touch of pride.
I'll lend him a hand now, and he'll surely take him."
助他一功 ("lend him an assist toward the merit"). Guanyin offers to intervene — setting off the friendly rivalry with Laozi over whose weapon will do it.
Lord Lao asked, "What weapon will the Bodhisattva use? How will you help him?"
甚兵器 ("what weapon"; 甚 = shén, "what"). Laozi's question is also a gentle challenge.
The Bodhisattva said, "I'll throw down that pure vase with its willow-sprig and strike the monkey on the head — even if it can't kill him, it'll give him a fall, so the young sage Erlang can take him."
淨瓶楊柳 ("the pure vase and willow-branch") are Guanyin's signature implements, usually instruments of mercy (the sweet dew that revives); here she proposes to use the vase as a missile.
Lord Lao said, "That vase of yours is porcelain — well and good if it strikes him, but if it misses his head, or hits his iron cudgel, won't it just shatter?
磁器 ("porcelain"); 打著/撞著 ("strike home" / "knock against"; 著 = zháo). Laozi's practical objection is also a quiet boast about his own indestructible weapon to come.
Don't make a move just yet — let me, old Lao, lend him the hand."
且莫動手 ("hold off for now"). Laozi takes over the task, and the rivalry tips in his favor.
The Bodhisattva asked, "And what weapon do you have?"
Guanyin's curiosity sets up the unveiling of the famous ring.
Lord Lao said, "I have, I have, I have."
The thrice-repeated 有 ("I have!") — a touch of comic relish as the old patriarch produces his treasure.
He pushed up his sleeve, took a bangle off his left upper arm, and said:
捋起衣袖 ("rolled up his sleeve"; 捋 = luō); 膊 (bó, "upper arm"); 圈子 ("a ring, a bangle"). The unassuming object is Laozi's most potent weapon.
"This weapon was forged of fine kun-steel, transmuted by my reverted elixir, nurtured to a body full of numinous force; it can transform at will, is proof against water and fire, and can lasso anything.
錕鋼 (kūn-gāng, a legendary fine steel); 摶煉 (tuán-liàn, "kneaded and refined, forged"); 還丹 (huán-dān, "the reverted cinnabar elixir" of inner alchemy). The ring is a product of Laozi's own alchemy — fire- and water-proof, transforming, and able to 套 (lasso) any object.
It is called the 'Diamond Jade-Cutter,' or else the 'Diamond Snare.'
金鋼琢 (jīn-gāng-zhuó, "diamond bangle"; 琢 = zhuó, a jade-cutting tool) / 金鋼套 ("diamond snare"). The two names stress its two virtues: hard as diamond, and a snare that catches all.
In years past, when I passed the Hangu Pass and converted the barbarians into Buddhas, I owed a great deal to it.
An allusion to the old 化胡為佛 ("converting the barbarians [into Buddhas]") legend — that Laozi, departing west through the Hangu Pass, became the Buddha or taught the western peoples. 甚是虧他 ("was much indebted to it"; 甚 = shèn, "very").
It's the best thing for self-defense at any hour. Let me throw it down and give him a knock."
早晚 ("morning or evening, at any time"); 防身 ("to guard oneself"). Laozi prepares the stroke that the next passage will deliver.
This passage is a small comedy of divine one-upmanship, and a revealing one. Guanyin, who recommended Erlang in the first place, claims a sponsor's pride in his performance and offers to finish the job with her own implements — the 淨瓶楊柳, the pure vase and willow-sprig that are everywhere else in the novel the instruments of her mercy (the vase holds the sweet dew that revives the dead and heals the sick). Here, charmingly, she proposes to use the holy vase as a projectile, to bean the monkey on the head. Laozi's objection is gently devastating and entirely practical: the vase is mere porcelain, and if it misses or strikes the iron cudgel it will simply break. The exchange has the texture of two old colleagues vying, with perfect courtesy, over who gets to land the decisive blow — and a quiet joke about the unsuitability of mercy's instruments for the work of force.
Laozi's weapon is the famous 金鋼琢, the Diamond Bangle, and the passage takes care to establish its pedigree, for it will become one of the novel's recurring marvels. Forged of legendary kun-steel and transmuted by Laozi's own reverted elixir, it is fireproof, waterproof, shape-shifting, and — crucially — able to "lasso anything" (套諸物). The detail that it played a part in the old 化胡為佛 legend — the Daoist tradition that Laozi, passing west out of the Hangu Pass, became the Buddha or converted the western peoples — is a sly bit of sectarian mischief on Wú Chéng'ēn's part, folding the Buddhist Guanyin's intervention and the Daoist patriarch's ring into a single scene that quietly asserts Daoism's priority. The two great Ways stand side by side at the gate, and it is the Daoist who strikes.
In the allegory, the choice of weapon is meaningful. The mind-monkey could not be beaten by force or caught by speed; even the mirror only located him. What finally subdues him is not a sharper blade but a snare — an object that does not wound but binds, that catches the protean thing and holds it fast. The Diamond Bangle's two names capture the logic exactly: it is hard as diamond (it cannot be broken by the cudgel as the porcelain vase could) and it is a snare (it does not kill but encircles). This is the third of the chapter's instruments of subduing, after the rout-by-stratagem and the all-seeing mirror, and it points forward to the greatest of them: the Buddha's palm, two chapters on, which will not strike the monkey at all but simply close over him. The pattern is consistent and pointed — the restless mind is mastered not by overpowering it but by containing it. (On the 化胡為佛 legend and the Diamond Bangle's later appearances, see the notes; 還丹, the "reverted elixir," is a central term of Daoist inner alchemy.)
