3.112

「此續生時定染污故」者，答。此意、捨二於續生時雖亦必有，定染污故，非是異熟，以據異熟為問答故。苦、樂、憂、喜、信等五根，初受生位雖亦成就，非異熟故、此亦不說。意、捨二根成而亦現尚非所說，況苦等九成而不現。理在絕言，故不別問。

"Because at this time of connecting existence, [the mind] is definitely defiled": this is the answer. Although these two, mind and equanimity, are also definitely present at the time of connecting existence, because they are definitely defiled, they are not maturation (vipāka), since the question and answer are formulated strictly on the basis of maturation. Although the five faculties of pain, pleasure, grief, joy, and faith and the rest are also possessed at the initial stage of taking birth, because they are not maturation, they are likewise not mentioned here. Even mind and equanimity, which are both possessed and manifest, are not mentioned; how much less the nine beginning with pain, which are possessed but not manifest? The reason is self-evident, and therefore no separate question is raised.
