成唯識論述記 3.780

3.780

述曰：雜染執藏過失重故，有漏二位名最初捨故，以二義故，此中偏說。唯說阿羅漢捨，不說捨異熟識等，此據捨縛。若據異熟識捨時，即阿賴耶同，故以體說異熟識捨，不說依縛異熟捨位。

The Commentary states: Because the fault of defiled grasping-as-storehouse is grave, and because it is the first to be relinquished among the two sāsrava stage-names, for these two reasons it is especially spoken of here. It only states that arhats relinquish it, not that they relinquish the vipākavijñāna, etc.; this is based on relinquishing bonds. If based on the time when the vipākavijñāna is relinquished, it is the same as the ālaya; therefore relinquishing the vipākavijñāna is spoken of in terms of substance, not speaking of the stage of relinquishing the vipāka based on bonds.
