維摩經略疏垂裕記 2.53

2.53

二、「今三」下，別釋，二：初、歷教委示。「但約二諦」者，道觀雙流故。「品有優劣」者，以八九十地相望故。

Second, from "Now three" onwards, specific explanation, in two parts: first, traversing the teachings to show them in detail. "Only in terms of the two truths": because the path and contemplation flow concurrently. "The grades have superior and inferior": because the eighth, ninth, and tenth grounds are viewed in relation to one another.
