俱舍論記 6.203

6.203

「滅雖別有至屬於彼事」者，說一切有部解云：滅雖別有，而由彼有漏事能緣惑得斷時，彼事解脫，方得此滅，可言此滅屬於彼事。此約得說屬。

Regarding "Although cessation exists separately ... it belongs to that thing": the Sarvāstivāda explains, saying: Although cessation exists separately, yet because at the time when the defilement that can take that sāsrava thing as an object is severed, that thing is liberated and only then is this cessation attained, one can say that this cessation belongs to that thing. This speaks of belonging in terms of acquisition (prāpti).
