俱舍論疏 21.101

21.101

論「若謂頌說至定何所從」，遮釋也。頌說「從所緣」言，意顯遍知所緣斷者，准前四種方便，非唯遍知所緣斷，亦有能緣斷，故斷等三種斷也。從其所緣，義即不定。

In the treatise, "If you say that the verse states […] from what determinately?" refutes the explanation. When the verse says "from the cognitive object", its intention is to show abandonment through thoroughly knowing the cognitive object; yet according to the four kinds of expedient means explained earlier, it is not only abandonment through thoroughly knowing the cognitive object, but also abandonment through the cognizing subject, and hence there are three kinds of abandonment including severance. [Abandonment] from its cognitive object is therefore indeterminate in meaning.
