詳曰：與轉為依，名為「轉依」。「轉」即能依，能依《論》說是染淨法，云何「轉」言屬能轉道？能轉道者非是染故。今釋「轉」者，而有二義：一云「轉」者屬能轉道，捨、得二種，轉之捨、得，依主為稱；二、屬所轉捨、得二種，轉即捨、得，持業立名。今依初義，合言「轉依」，亦依主釋。

Detailed analysis: Providing a basis for transformation is called 'transformation of the basis'. 'Transformation' is that which relies on the basis; that which relies on the basis is explained by the Treatise as defiled and pure dharmas—how could the word 'transformation' belong to the path that can transform? The path that can transform is not defiled. Now explaining 'transformation', there are two meanings: One says 'transformation' belongs to the path that can transform: the two kinds, discarding and attaining—the discarding and attaining of transformation, named as a genitive compound (tatpuruṣa). The second is that it belongs to the two kinds of discarding and attaining that are transformed: transformation is precisely discarding and attaining, established as an appositional compound (karmadhāraya). Now, according to the first meaning, the combined phrase 'transformation of the basis' is also interpreted as a genitive compound.
