逐句解 Line by line
The Bodhisattva said: "Tang Monk, the one who struck you the other day was the false Pilgrim, a Six-Eared Macaque.
The verdict is delivered to Tripitaka in nineteen characters with no preamble: the plain fact he has been unable to establish for himself.
By the Tathāgata's good knowledge of him, he has already been struck dead by Wukong.
幸如來知識 — fortunately the Tathāgata knew him. 知識 here is the plain sense of knowing and recognising, not the modern noun meaning knowledge.
You must now take Wukong back in. The demon-barriers along the road are not yet done with; you will have to have him guard you, and only so will you get to the Numinous Mountain, see the Buddha and fetch the scriptures. Give over your resentment."
The argument is from necessity, not from justice. 必得 takes děi, the everyday "have to" — a third reading of the character, standing four characters away from the dé of 才得到 in the same sentence.
Tripitaka knocked his head and said: "I shall respectfully obey the instruction."
Nine characters, and they are the whole of Tripitaka's answer to a chapter that began with him throwing Wukong out. 教旨 takes jiào, an instruction from a superior.
Guanyin does not ask; she instructs. 你今須是收留悟空 — you must now take Wukong back in — and the reason she gives is purely practical: there are demons still on the road ahead and you will not survive without him. 必得他保護你，才得到靈山 argues from necessity, not from justice.
That is a deliberate choice on the novel's part. Nobody tells Tripitaka he was wrong. Nobody makes him apologise. The reconciliation is arranged over his head by a Bodhisattva acting on the Buddha's word, and his part in it is four characters of compliance: 謹遵教旨.
再休嗔怪 — give over your resentment — is the closest the chapter comes to addressing the original quarrel, and it is addressed to the master rather than to the disciple. The expulsion that set five thousand characters in motion is closed with an instruction not to be annoyed.
