「頌曰至亦不能斷」者，諸無漏定皆能斷惑。本淨尚無能，況諸染能斷。以勝況劣。謂本淨定不能斷下地，已離染故。不能斷自地惑，以自地惑所縛故。不能斷上地，以勝己故。若淨近分亦能斷惑，以皆能斷次下地故。又《婆沙》一百六十二云「問：何故有漏道不能斷自地及上地，無漏道則能斷耶？答：以無漏道是不繫法，於有漏法無非是勝，是故能斷。又有漏道作六行相，厭下地欣自地，故唯斷下。無漏道作十六行相，厭背一切地，故能遍斷。問：有漏道亦作十六行相，何故不能遍斷？答：彼雖學作聖道行相，不明了故不斷煩惱，如師子子未能害獸（已上論文）。」若中間攝淨亦不能斷，如根本說。

Regarding 'The verse says ... also cannot sever': all uncontaminated concentrations can sever defilements. Even the fundamentally pure lacks the capacity, how much less could defiled ones sever! This illustrates the inferior by means of the superior. That is to say, fundamentally pure concentration cannot sever lower stages, because defilement has already been abandoned; it cannot sever defilements of its own stage, because it is bound by defilements of its own stage; it cannot sever higher stages, because they surpass itself. Pure threshold states can also sever defilements, because all can sever the stage immediately below. Furthermore, fascicle 162 of the *Vibhāṣā* says: 'Question: Why can contaminated paths not sever their own stage and higher stages, while uncontaminated paths can sever them? Answer: Because the uncontaminated path is an unbound dharma, and is nothing other than superior to contaminated dharmas; therefore, it can sever them. Furthermore, the contaminated path adopts six aspects, loathing lower stages and longing for its own stage, hence it severs only the lower. The uncontaminated path adopts sixteen aspects, turning away from all stages, hence it can sever universally. Question: The contaminated path also adopts sixteen aspects; why can it not sever universally? Answer: Although it trains in producing the aspects of the noble path, because it is not distinct, it does not sever defilements, just as a lion cub is not yet able to kill beasts.' Pure [concentrations] subsumed under intermediate [dhyāna] also cannot sever, just as explained for the fundamental.
