俱舍論記 5.193

5.193

「雖餘部說至不應正理」者，此即經部破正量部滅相。正量部計：薪等經多時住，薪等滅時由二緣滅：一內滅相、二外火等。住、滅別時，若心、心所等，唯由內滅相，非由外緣。故今破言：雖餘正量部說薪等遇外火等能滅因緣，內滅相方能滅所滅薪等。而彼所說應如有言：服瀉藥時，天來令利。即火等滅因緣，應滅所滅薪等，何須別執有滅相為？又薪等法待外緣滅，汝宗可說先住後滅二不同時。心、心所法，依汝宗中許剎那滅，更不須待餘外滅緣，應住用時即起滅用，如何彼執諸相起用前後別時？若住相時亦起滅用，是則一法於一時中亦住亦滅，不應正理。

Regarding "Although other schools say ... it does not accord with correct reasoning": Here the Sautrāntika refutes the characteristic of cessation of the Saṃmatīya school. The Saṃmatīya maintains: Firewood and so forth abide for a long time, and when firewood and so forth cease, they cease through two conditions: first, an internal characteristic of cessation; second, external fire and so forth. Stationariness and cessation occur at different times; but regarding mind, mental factors, and the like, they cease solely through the internal characteristic of cessation, not through external conditions. Therefore, it is now refuted: Although other [schools, such as the] Saṃmatīya, say that only when firewood and so forth encounter external fire and so forth as destructive causes and conditions can the internal characteristic of cessation destroy the firewood and so forth to be destroyed, what they say is like saying: When taking a laxative, a deva comes and causes the purging! The destructive causes and conditions, such as fire, should themselves destroy the firewood and so forth to be destroyed; why must one separately grasp at the existence of a characteristic of cessation? Furthermore, if phenomena such as firewood depend on external conditions to cease, your school could say that prior stationariness and subsequent cessation are two that are not simultaneous. But mind and mental factors, according to your school, are admitted to perish in a single moment, without needing to depend on other external conditions of cessation; at the time of the operation of stationariness they should initiate the operation of cessation. How can they hold that the operations initiated by the characteristics occur at different times, one after another? If at the time of the characteristic of stationariness they also initiate the operation of cessation, then a single phenomenon at one time would both abide and cease, which does not accord with correct reasoning.
