摩訶止觀 5.237

5.237

若前念亦滅亦不滅後念生者：若滅，已屬滅；若不滅，已屬不滅；若不滅合滅能生，即是共生。共生自相違，相違何能生？又若各各有生，即有二過；各各無生，合亦不生。若滅不滅中有生性者，為有？為無？若性定有，何謂滅不滅？若性定無，亦何謂滅不滅？此不免斷、常之失，還墮共過。

If the subsequent thought arises when the prior thought has both ceased and not ceased: if it has ceased, it already belongs to cessation; if it has not ceased, it already belongs to non-cessation. If non-cessation combined with cessation can produce [the thought], this is arising from both. Arising from both is internally contradictory; how can contradictory things produce anything? Furthermore, if each individually possesses arising, there are two faults; if each individually lacks arising, their union also does not produce it. If there is a nature of arising within both cessation and non-cessation, does it exist or does it not exist? If the nature definitely exists, how could it be cessation and non-cessation? If the nature definitely does not exist, how could it also be cessation and non-cessation? This does not avoid the faults of annihilation and permanence, and falls back into the fault of arising from both.
