巽宮煉睛 Into the Eight-Trigram Brazier
那老君到兜率宮,將大聖解去繩索,放了穿琵琶骨之器,推入八卦爐中,命看爐的道人、架火的童子,將火搧起鍛煉。原來那爐是乾、坎、艮、震、巽、離、坤、兌八卦。他即將身鑽在巽宮位下。巽乃風也,有風則無火。只是風攪得煙來,把一雙眼火煼紅了,弄做個老害病眼,故喚作「火眼金睛」。那老君到兜率宫,将大圣解去绳索,放了穿琵琶骨之器,推入八卦炉中,命看炉的道人、架火的童子,将火搧起锻炼。原来那炉是干、坎、艮、震、巽、离、坤、兑八卦。他即将身钻在巽宫位下。巽乃风也,有风则无火。只是风搅得烟来,把一双眼火煼红了,弄做个老害病眼,故唤作「火眼金睛」。

Laozi came to the Tushita Palace, loosed the Great Sage's cords, drew out the spike that had pierced his collarbone, and thrust him into the Brazier of the Eight Trigrams; he ordered the brazier-tending Daoist and the fire-stoking lad to fan the flames up and refine him.
兜率宮 (Dōushuài Gōng) — Tuṣita, Laozi's heaven. 琵琶骨 (pí pá gǔ), the "lute-bone" (collarbone/scapula region), through which the captive had been pinned. Both 將s are the disposal-jiāng. 搧 (shān), to fan.
Now that brazier was set by the Eight Trigrams — Qian, Kan, Gen, Zhen, Xun, Li, Kun, Dui. He at once thrust himself in beneath the Xun position.
The eight 卦: 乾 qián (Heaven), 坎 kǎn (Water), 艮 gèn (Mountain), 震 zhèn (Thunder), 巽 xùn (Wind), 離 lí (Fire), 坤 kūn (Earth), 兌 duì (Lake). 將身 again disposal-jiāng. The monkey's choice of 巽 is pure cunning, explained next.
Xun is Wind, and where there is wind there is no fire. Only, the wind churned up smoke, which seared his pair of eyes fire-red, leaving them like an old man's chronic sore eyes — and so they came to be called the "Fiery Eyes and Golden Pupils."
The trick: 巽 (Wind) is the one trigram-position with no flame, so the monkey hides there. But wind-driven smoke does what fire could not — it sears his eyes. 一雙: 一 before 雙 (shuāng, 1st tone) is yì. 煼 (chǎo), to scorch with smoke. The injury becomes his most famous gift: 火眼金睛, eyes that see through every disguise.
This short passage delivers one of the most beloved origin-details in the novel: how Sun Wukong acquired his 火眼金睛, the "fiery eyes and golden pupils" that let him see through any transformation. The mechanism is a small masterpiece of allegorical wit. Placed in the brazier to be reduced to ash, the monkey reads the 八卦 structure of the furnace and hides in the 巽 (Wind) position — for "where there is wind, there is no fire."
But the cleverness is incomplete. Wind without fire still carries smoke, and seven times seven days of smoke do to his eyes what flame could not. The injury is real — his eyes end "red as an old man's sore eyes" — yet it is precisely the wound that becomes the power. In the inner-alchemical reading, the 心猿 placed in the crucible is not annihilated but transmuted: the refining that was meant to destroy him instead sharpens his discernment. The 易經 trigrams are not decoration here; the monkey survives by reading the pattern of Wind and Fire, the very competence the pilgrimage will later demand of the disciplined mind.
The lute-bone detail (琵琶骨) recalls his capture in Chapter 6: a spike driven through the collarbone was the standard way, in this fictional cosmology, to immobilize a shape-shifter and prevent transformation. Laozi removes it — confident the furnace needs no such restraint — which is exactly the overconfidence the next passage punishes.
