5.168

「故說頌言至相續說住」者，引頌證。此三行頌，竝是經部諸師說頌。前兩行顯於相續立生等相，文異義同；後一頌破說一切有部剎那實住。由諸法剎那無有實住而有假滅，彼法生已不待外緣，剎那剎那自然滅故。於剎那中執有實住，是為非理；是故唯於相續說住，非約剎那。

Regarding "Therefore the verse says ... duration is spoken of with respect to the continuum": citing verses as proof. These three lines of verse are all verses spoken by the Sautrāntika masters. The first two lines reveal that the characteristics of origination, etc., are established upon the continuum, differing in words but identical in meaning; the latter verse refutes the Sarvāstivāda's claim of real duration within a moment. Because dharmas have no real duration within a moment but have provisional cessation, once that dharma has arisen, it does not await external conditions, but naturally ceases moment by moment. To cling to real duration within a moment is unreasonable; therefore, duration is spoken of solely with respect to the continuum, not with respect to a single moment.
