俱舍論記 3.22

3.22

「於眾同分至各能為根」者，釋第二頌。由有命根故、同分得住故，於眾同分，命有增上用。由五受故、起諸煩惱故，於雜染中五受有增上用。引證可知。經約三受不言憂、喜，以苦攝憂，以樂攝喜。信等五根於清淨中有增上用，由此信等善根勢力，伏諸煩惱、引聖道生。餘文可知。

"Over the commonality of sentient beings... [up to] each can function as a faculty": this explains the second verse. Because the life faculty exists, the commonality is able to endure; therefore, over the commonality of sentient beings, life has sovereign efficacy. Because of the five feelings, the defilements arise; therefore, in defilement the five feelings have sovereign efficacy. The cited proofs are clear. The sūtra speaks in terms of three feelings without mentioning grief and joy, because grief is subsumed under suffering, and joy is subsumed under pleasure. The five faculties beginning with faith have sovereign efficacy in purification: through the power of these wholesome faculties of faith and the rest, defilements are subdued and the noble path is induced to arise. The rest of the text is clear.
