Boqin could only call the servants and have the horses led along.

只得 ("could only," read dé) again marks a reluctant necessity — here Boqin's agreement to make the ascent and marshal the party.

He then supported Sanzang and climbed once more up the high mountain; clutching vines and clinging to creepers, they made their way to the very summit,

The scramble up — 攀籐附葛, "clutching vines and clinging to creepers" — conveys the roughness of the peak. Sanzang, physically weak, must be supported the whole way.

where indeed they saw ten thousand shafts of golden light and a thousand strands of auspicious vapour. There stood a great four-square boulder, and pasted upon it was a paper wrapper bearing six golden graphs: 唵嘛呢叭𠺗吽.

The summit is wrapped in the standard signs of the sacred — golden light and auspicious mist. The six graphs are the great mantra 唵嘛呢叭𠺗吽, a phonetic transcription of the Sanskrit Oṃ maṇi padme hūṃ, the six-syllable mantra of Avalokiteśvara (Guanyin). The rare graph 𠺗 (U+20E97) is used purely for its sound; the reading given here — ǎn má ní bā mī hōng — follows the conventional Mandarin recitation of the mantra.

Sanzang came forward and knelt; facing the graphs upon the stone, he made several bows, and turning toward the west he prayed:

Sanzang approaches the Buddha's seal with full ritual deference, kneeling and bowing before he dares to touch it.

"Your disciple, Chen Xuanzang, has come by imperial command to seek the scriptures. If it is my destined lot to have a disciple, let me peel off these golden words, free the divine monkey, and together attain the Numinous Mountain. But if no such lot is mine — if this be some fierce and stubborn monster deceiving your disciple, unworthy of any blessing — then let the words not come away."

The prayer turns the rescue into an ordeal of destiny. 陳玄奘 is the monk's name (his lay surname Chen with the monastic Xuanzang); 徒弟之分, "the destined lot of discipleship" (分 read fèn, "allotted fate"), is what he asks Heaven to confirm. 靈山, the "Numinous Mountain" (Gṛdhrakūṭa, Vulture Peak), is the Buddha's seat and the pilgrimage's goal. He frames the test plainly: if the seal lifts, the monkey is his fated disciple; if not, a fraud.

His prayer done, he bowed again; and when the bowing was finished, he stepped forward and gently peeled the six golden graphs away.

The seal yields to a gentle touch — the sign that the destiny is real. 將 is again the object-marker, read jiāng.

At once a gust of fragrant wind arose, snatched the seal-strip from his hand, and swept it up into the air, while a voice cried: "I am the Guardian appointed to press down the Great Sage. Today his ordeal is fulfilled, and we return to see the Tathāgata and deliver back this seal."

The talisman does not merely fall: a fragrant wind carries it off, and the guardian spirits announce that they are returning it to the Buddha now that the sentence is served. 難滿 ("the ordeal is complete," 難 read nàn) formally ends Wukong's five-hundred-year term.

So startled were Sanzang and Boqin and all their party that they bowed toward the empty sky.

嚇得 ("so startled that," 得 read de) marks the party's awe; they can only bow to the vanished spirits.

Then they went straight down the mountain and came again to the stone chest, where Sanzang said to the monkey, "The seal is peeled away — you may come out now."

The scene returns to the prison to release its prisoner. Sanzang's plain announcement — the seal is gone, come out — completes his part in the rescue.

The monkey rejoiced and called, "Master, please stand off a little, so that I may come out without alarming you."

The monkey's courtesy — asking the monk to step back lest the eruption alarm him — is a small, almost comic touch before the mountain splits and he bursts free in the next passage.
