大般涅槃經義記 8.327

8.327

下佛答之，文別有四：先答第三、次答第二、復答第三、却答第一，故有四文。初言「須陀雖生惡國，終不失於須陀名」者，答第三中若惡國陰非須陀洹，明雖生惡不得言非。「陰不相似，是故我引犢子為喻」，答第二難，明後過前。非直相似，是故說言陰不相似。如犢飲乳初飢後飽，云何不似？去涅槃界近於前故。

Below, the Buddha answers him; the text has four distinct parts: first answering the third, next answering the second, then answering the third again, and finally answering the first; hence there are four passages. First, saying "although a srotāpanna is born in an evil land, he ultimately does not lose the name of srotāpanna" answers the point in the third [objection] that if the aggregates in an evil land are not a srotāpanna, explaining that although born in an evil [land], one cannot say he is not [a srotāpanna]. "The aggregates are not similar, which is why I cited the calf as an analogy" answers the second objection, explaining that the later surpasses the earlier. They are not merely similar; therefore it is said that the aggregates are not similar. Just as when a calf drinks milk, it is hungry at first and satiated later, why are they not similar? It is because he is closer to the realm of nirvāṇa than before.
