太尉引路 Marshal Zhu Leads the Way
那太尉執一首引魂旛,在前引路。崔判官隨後保著太宗,徑出幽司。太宗舉目而看,不是舊路,問判官曰:「此路差矣?」判官道:「不差。陰司裡是這般,有去路,無來路。如今送陛下自轉輪藏出身,一則請陛下遊觀地府,一則教陛下轉托超生。」太宗只得隨他兩個引路前來。那太尉执一首引魂旛,在前引路。崔判官随后保着太宗,径出幽司。太宗举目而看,不是旧路,问判官曰:「此路差矣?」判官道:「不差。阴司里是这般,有去路,无来路。如今送陛下自转轮藏出身,一则请陛下游观地府,一则教陛下转托超生。」太宗只得随他两个引路前来。
逐句解 Line by line
The marshal took up a soul-guiding banner and went before to lead the way.
The 引魂旛, yǐn hún fān, is a soul-guiding pennant, the banner carried before a funeral procession to show the spirit the way. 一首 here serves as its counter — the little word Chinese requires between a number and a noun, as English requires "a sheet of" paper.
Magistrate Cui followed behind, guarding Taizong, and they passed straight out of the shadow-court.
保著 uses zhe to hold the action open: guarding him, all the way. 幽司 is the dark administration, the offices of the dead.
Taizong lifted his eyes and saw that this was not the road by which he had come, and asked the magistrate, 'Is this the wrong way?'
The emperor notices they are not retracing their steps. 差矣 is "is this wrong?"; 差 here is chà, mistaken — not chāi, to dispatch, which is the same character two lines earlier.
'Not wrong,' said the magistrate. 'It is so in the world of shade: there is a road out, but no road back.'
The magistrate's answer is the best single line in the chapter's geography: 有去路,無來路 — there is a way out, there is no way back. The underworld is a one-way system, and the exit is not where you came in.
'Now we send Your Majesty out by way of the Wheel of Transmigration — for one thing, to let you tour and behold the Land of Shades; for another, to set you toward rebirth and deliverance.'
轉輪藏 is the turning Wheel of Rebirth; 藏 is zàng. The pattern 一則…一則 is "for one thing… for another," with 一 read yī. 轉托超生 is to pass through rebirth toward release. Two reasons, given in the tone of a guide explaining a detour: you may as well see the sights, and it happens to be the road to salvation.
Taizong could only follow the two of them as they led the way forward.
只得, with 得 as dé, is "had no choice but to." The route home is also the tour of hell, and it fills the next dozen passages.
The way home is deliberately not the way in. The magistrate explains the underworld's one-way logic and, in the same breath, reframes the tour of hell as both sightseeing and a passage through the Wheel of Rebirth.
The passage is a hinge: it turns the chapter from the tribunal, which is over, toward the long descriptive tour that follows — and it puts the emperor in the position the book wants him in, that of a witness being shown something he will have to report.
