逐句解 Line by line
Pilgrim said, "That trick really is neat, and it works."
妙而且靈 pairs two kinds of praise: 妙 is clever or elegant, 靈 is efficacious, the word used of a medicine that does what it promises or a shrine that answers prayers.
He resumed his own shape, went up close, and called, "Master."
Three short clauses. After a night of transformations he simply walks up and says the word.
The Tang Monk heard and said, "Wukong, save me!"
Ten characters, and it is the first time tonight anybody has used Wukong's dharma name. His master reaches for it the moment there is hope.
Sha Monk said, "Brother, are you calling from outside?"
The question of a man in a covered basket who cannot see. It is also, accidentally, the question the whole chapter has been asking about where Wukong is.
Wukong congratulates himself before he does anything else, and the phrase he chooses is a craftsman's: neat, and it works. Elegance and efficacy, in that order.
Then three voices in three sentences, and each reveals its speaker. The master calls him by his religious name and asks to be saved. Sha Monk, who cannot see, asks a practical question about position. Neither of them can do anything, and both respond exactly in character.
The name is the detail to keep. Tripitaka has called him disciple all night. Wukong — awakened to emptiness — is the name Subodhi gave him and the name the master uses when he wants something.
