捎書寄信 The Bargain of the Letter
唐僧道:「貧僧乃是差往西天取經者,不期閑步,誤撞在此。如今要拿住我兩個徒弟,一齊蒸吃哩。」那公主陪笑道:「長老寬心,你既是取經的,我救得你。那寶象國是你西方去的大路,你與我捎一封書兒去,拜上我那父母,我就教他饒了你罷。」三藏點頭道:「女菩薩,若還救得貧僧命,願做捎書寄信人。」唐僧道:「贫僧乃是差往西天取经者,不期闲步,误撞在此。如今要拿住我两个徒弟,一齐蒸吃哩。」那公主陪笑道:「长老宽心,你既是取经的,我救得你。那宝象国是你西方去的大路,你与我捎一封书儿去,拜上我那父母,我就教他饶了你罢。」三藏点头道:「女菩萨,若还救得贫僧命,愿做捎书寄信人。」
逐句解 Line by line
Tripitaka said, 'This poor monk is one dispatched to the Western Heaven to fetch the scriptures. Walking idly, I strayed and blundered in here unawares; and now he means to seize my two disciples and steam and devour us all together.'
差往 frames the mission as an imperial commission (差 = chāi, "to be sent on charge"). 貧僧 ("this poor monk") is Tripitaka's self-deprecating first person. The blunt 一齊蒸吃 ("steamed and eaten all together") states the ogre's culinary intent with the tale's characteristic matter-of-factness; sentence-final 哩 is the light particle li.
The princess said with a coaxing smile, 'Set your heart at ease, elder. Since you are a scripture-seeker, I can save you. That Land of Precious Images lies on your high road westward; carry a letter there for me, pay my respects to my father and mother, and I shall have him spare you.'
陪笑 ("an ingratiating smile") signals the stratagem. 救得你 takes 得 as the potential-complement de ("am able to save you"), distinct from the modal dé of 得會 above. The letter is named 書兒, the diminutive 兒 (suffix er) marking it an intimate note; 就教他饒了你 has 教 as the causative jiào, "I shall make him let you go." This bargain is the chapter's hinge.
Tripitaka nodded and said, 'Bodhisattva-lady, if indeed you would save this poor monk's life, I am willing to be the bearer of your letter and the carrier of your word.'
若還 ("if indeed") takes 還 as hái; 救得 again the potential de. 捎書寄信人 ("carrier-of-the-letter, sender-of-the-word") formalizes Tripitaka's new office in a characteristic vernacular binome (捎書/寄信). His readiness, born of desperation, will shortly oblige him to speak a falsehood (誑語) at court — a scruple he raises in the scene that follows.
The bargain of the letter is the structural pivot of the entire chapter. In the space of three speeches the princess converts a doomed captive into a diplomatic instrument: her stratagem (陪笑) trades Tripitaka's life for the delivery of a message to her royal parents, and in doing so launches the embassy to the Land of Precious Images that will draw the two disciples to court, set the king weeping over the letter, and precipitate the renewed assault on the Yellow-Robe ogre.
The exchange is also quietly moral. Tripitaka accepts the commission of 捎書寄信 out of naked necessity, and the reader is meant to feel the pressure of it: to keep his word to her he will, at the Baoxiang court, have to dissemble about the fate of the princess's children, and he flags his own scruple against 誑語 ("false speech") almost as soon as he takes the letter. The intimate diminutive 書兒 keeps the human scale of the transaction in view even as it sets the chapter's larger machinery turning.
