俱舍論疏 6.140

6.140

論「若爾至染污思」，外人難也。既離欲聖人退，最初起染污思是唯不善為因，故知聖人身中染法不用見道所斷身、邊二見為因。

The treatise says: "If so, [...] defiled volition." This is an objection by an opponent. Since when a noble one who has departed from desire falls away, the initially arisen defiled volition takes solely the unwholesome as its cause, we know that the defiled phenomena in a noble one's stream of being do not take the view of self-existence and extreme views, which are abandoned by the path of seeing, as their causes.
