俱舍論疏 5.213

5.213

論「又住用息至更無所為」，又遮難也。若住不由有障暫用自息，即應法自然壞滅，何用異、滅二相？

On the treatise passage: "Furthermore, if the function of staying ceases … there would be nothing further for them to do": they further refute the objection. If staying, without being obstructed, ceases its temporary function naturally of itself, then the phenomenon should naturally disintegrate and cease; what need would there be for the two characteristics of alteration and cessation?
