2.50

下約前喻教勸比丘，句別有四：一約初喻呵其取偽、二約第三教其取真、三約第二勸知昔偽、四重約第三勸取今真。初中「汝等不應修習無常等想以為實」者，約喻以呵。「如彼人」下，舉喻類責。「汝等應當善學方便，處處常修常樂淨等」，約第三喻教修趣實，生生恒習故云處處。「復應當知先所修習四法相貌悉是顛倒」，約第二喻勸知昔偽。下重約第三勸修今真，「欲得如是修諸想者」，舉其所求。「如智出珠」，約喻以勸。「所謂我」等，辯出所修。

Below, it instructs and exhorts the monks based on the preceding analogies, with four distinct sentences: 1) based on the first analogy, reprimanding their taking the false; 2) based on the third, teaching them to take the genuine; 3) based on the second, exhorting them to know their past falsehood; 4) based once more on the third, exhorting them to take the present genuine. In the first, "You should not cultivate the perceptions of impermanence and so forth, taking them to be real" reprimands them based on the analogy. From "Just like that person..." onward, it cites the analogy to reprove them by comparison. "You should skillfully learn expedient means, constantly cultivating permanence, bliss, purity, and so forth in every place" teaches cultivating to proceed toward the real based on the third analogy; constantly practicing it life after life is why it says "in every place". "You should furthermore know that the characteristics of the four dharmas previously cultivated are all inversions" exhorts them to know their past falsehood based on the second analogy. Below, based once more on the third, it exhorts them to cultivate the present genuine: "those who wish to cultivate such perceptions" raises what they seek; "like a wise person bringing out the gem" exhorts them based on the analogy; "namely, self..." and so forth distinguishes what is to be cultivated.
