土母調和 The Earth-Mother's Mediation
那長老聽說,一時解悟,明徹真言。滿心歡喜,稱謝了悟空。沙僧在傍笑道:「師兄此言雖當,只說的是弦前屬陽,弦後屬陰,陰中陽半,得水之金;更不道:那长老听说,一时解悟,明彻真言。满心欢喜,称谢了悟空。沙僧在傍笑道:「师兄此言虽当,只说的是弦前属阳,弦后属阴,阴中阳半,得水之金;更不道:

The elder, hearing this, in a moment grasped it and understood clearly the true words.
解悟 "to comprehend, awaken to"; 明徹 "to understand thoroughly"; 那 read nà, 長 read zhǎng.
Filled with joy, he thanked Wukong.
稱謝 "to express thanks"; 了 the aspect particle le.
Sha Monk, at his side, said with a smile: “Brother, though your words are apt, they tell only of how before the quarter belongs to yang and after the quarter to yin — the yang half within the yin, the metal that has got its water;”
在傍 "at the side," 傍 read páng; 雖當 "though apt/correct," 當 read dàng; 陰中陽半 "yang half within yin," 中 read zhōng; 得水之金 "the metal that has obtained water," 得 read dé — the fusion of metal (yang) and water (yin).
but he does not go on to say:
更不道 "does not further say," 更 read gèng. Sha Monk offers a completing verse.
Water and fire mingle, each by its own affinity, relying wholly on the Earth-Mother to match them so.
相攙 "to blend, mingle," 相 read xiāng, 攙 read chān; 土母 "the Earth-Mother," the element Earth (spleen / intention) that mediates and harmonizes the other agents — in Five-Agent alchemy, Earth is the go-between uniting Water and Fire.
When the three houses meet together without contention — water lies in the long river, the moon hangs in the sky.
三家 "the three houses," the agents brought into union; 長江 "the long river," 長 read cháng. The closing image: perfect equilibrium, each thing in its place, water below and moon above.
Tripitaka grasps Wukong's teaching at once, and Sha Monk — usually the most reticent of the disciples — steps forward to complete it. His point is that Wukong has described only half the process: the mingling of yang and yin (the "metal that has got its water") still requires a mediator. His verse supplies it: Water and Fire cannot unite of themselves but must be matched by the "Earth-Mother," the agent Earth that in Five-Agent alchemy harmonizes the others.
The passage deepens the symposium by adding the doctrine of the "three houses" brought into concord through Earth's mediation — a standard refinement of the internal-alchemical scheme, in which the intention or true-earth reconciles the opposed forces. Sha Monk's closing couplet resolves the whole discourse into a serene image of things in their right places: "water in the long river, the moon in the sky." That each disciple contributes a further turn of the doctrine is itself significant — the moon becomes an occasion for the pilgrims' shared understanding, a collaborative unfolding of the teaching.
