俱舍論疏 24.179

24.179

論「又世俗道至沙門果體」，第二釋也。諸聖者世俗道斷惑之時，必兼無漏斷得持故，從無漏得，名沙門果體。「退不命終」者，據得果位，非是向位。

The treatise says: 'Furthermore, the mundane path, up to: the essence of the fruit of asceticism'—this is the second explanation. When noble ones sever defilements via the mundane path, it is necessarily maintained concurrently by untainted acquisitions of abandonment; derived from the untainted acquisition, it is named the essence of the fruit of asceticism. 'Falling back without dying' is stated in terms of the stage of having attained the fruit, not the candidate stage.
