摩訶止觀 5.32

5.32

成不成者，若發一境，究竟成就；成就已謝，更發餘境，餘境亦究竟成。若發一種，作起、乍滅，非但品數缺少，於分分中亦曖昧不明。前具不具止明頭數，此中論體，分始終。

"Accomplished or unaccomplished" means: if a realm arises and is definitively accomplished; and after its accomplishment it fades, and another realm arises, and the other realm is also definitively accomplished. If one kind arises, suddenly emerging and suddenly vanishing, not only are its grades deficient in number, but even within its components it is vague and unclear. The previous [pair] "complete or incomplete" merely clarified the head-count, whereas here it discusses the substance, distinguishing beginning and end.
