6.182

「非擇為先至方有不生」者，經部答。非擇為先方有擇滅，如何責我擇滅體性亦是無常？所以者何？非先有擇，後未來未生法方不生。不生即擇滅也。

On "It is not that having deliberation as its precursor [up to] only then is there non-arising": the Sautrāntika answers. It is not that deliberation must precede for pratisaṃkhyā-nirodha to exist; how can you reproach me by saying that the intrinsic nature of pratisaṃkhyā-nirodha is also impermanent? Why is this? It is not that deliberation exists first and only afterward do the unarisen dharmas of the future not arise. Non-arising is itself pratisaṃkhyā-nirodha.
