2.190

此難權智生滅，先立理也，因前辨析已許二智不住有無。然其下，權智應機之時大小無差，機熟為可應，未熟者與作得度之緣，故云存之。

This objection concerns the arising and ceasing of upāya-jñāna, first establishing the principle. Following the earlier distinctions, it has already been conceded that the two wisdoms do not abide in being or non-being. From "its way" onward, when upāya-jñāna responds to capacities, it never errs regarding the great or the small; when capacities are mature, it can respond to them, and for those that are not yet mature, it provides conditions for their future deliverance; hence it is said, "leaves aside."
