俱舍論疏 14.90

14.90

論「彼聲為顯至簡取無漏」，釋頌「彼聖」兩字。彼謂前靜慮，靜慮通漏、無漏故。聖唯簡取無漏，有漏非聖體故。

As for the treatise stating, "The word 'that' is to indicate […] specifically selects the undefiled": this explains the two words 'that noble' in the verse. 'That' refers to the preceding dhyāna, because dhyāna encompasses both defiled and undefiled. 'Noble' specifically selects the undefiled, because the defiled is not the essence of the noble.
