5.151

流是下。解科文。此即四諦之中，前二世間因果也。大雲解云：集招苦果故說為流，生死不停故名為轉。斯則襲習綸輪之義也。

"Flowing is...", etc.: Explains the outline text. This refers to the first two, worldly cause and effect, within the Four Noble Truths. Dayun explains: because the origin (samudaya) brings about the fruit of suffering, it is called "flowing"; because birth and death do not cease, it is called "turning". These carry the senses of continual accumulation and the turning of a wheel.
