俱舍論疏 3.29

3.29

論「於眾同分至各能為根」，釋第二頌。言「於眾同分住中命根有增上用」者，釋命根也。言「於雜染中至無明隨增故」，釋五受根增上用也。言「於清淨中至引聖道故」，釋信等五根有增上用。言「言應知者至各能為根」，此釋頌中「應知」字也。

On the Śāstra's: "With respect to generic conformity […] each can constitute a faculty": this explains the second verse. The statement "The life-faculty has predominant efficacy with respect to the abiding of the generic conformity" explains the life-faculty. The statement "With respect to defilement […] because ignorance increases in accordance" explains the predominant efficacy of the five feeling faculties. The statement "With respect to purification […] because they lead to the noble path" explains that the five faculties of faith and the rest have predominant efficacy. The statement "The word 'should be known' […] each can constitute a faculty" explains the words "should be known" in the verse.
