雷音勝境 Barred At Thunderclap
大眾舉目看之，果是兩個行者，吆天喝地，打至雷音勝境。慌得那八大金剛上前擋住道：「汝等欲往那裡去？」這大聖道：「妖精變作我的模樣，欲至寶蓮臺下，煩如來為我辨個虛實也。」大众举目看之，果是两个行者，吆天喝地，打至雷音胜境。慌得那八大金刚上前挡住道：「汝等欲往那里去？」这大圣道：「妖精变作我的模样，欲至宝莲台下，烦如来为我辨个虚实也。」

The whole assembly raised their eyes and looked; and sure enough there were two Pilgrims, bawling at heaven and shouting at earth, fighting their way into the holy precinct of Thunderclap.
吆天喝地, bawling at heaven and shouting at earth. 喝 takes hè, to shout, under the standing ruling; the automatic reading gives hē, which belongs to drinking.
This so alarmed the eight great Vajrapāṇis that they came forward and barred the way: "Where would you two be going?"
Both readings of 那 stand inside these nineteen characters: 那八大金剛 points at them, nà, and 那裡去 asks where, nǎ. 慌得 takes the light de.
This Great Sage said: "A fiend has changed himself into my likeness. I would go below the precious lotus dais and trouble the Tathāgata to tell the false from the true for me."
Notice what he no longer asks for. 為我辨 takes wèi, on my behalf — against the wéi that means "is taken for" and governs 非有為有 in the discourse two passages back.
The pair arrive at the last court in the cosmos and are met, as at every gate before it, by guards asking where they think they are going. The chapter has now run this beat four times — the Dharma-guarding devas, the South Heaven Gate, the gate of the shades, and now the Vajrapāṇis — and each time the institutional reflex is to treat the problem as trespass.
Wukong's request has changed shape, though. He no longer asks anybody to look. 煩如來為我辨個虛實 — trouble the Tathāgata to tell false from true for me — drops the whole vocabulary of vision, the eye of wisdom and the strength of the eyes, that he used at Potalaka and in Heaven. Since Diting he seems to have grasped that what he needs is not a better observer.
