淨名經集解關中疏 2.464

2.464

是時佛告舍利弗。有國名妙喜。佛號無動。是維摩詰於彼國沒而來生此　此下二明應身應土文二。初論應事。二現身土。前文又四。一佛示國名。二身子生疑。三約喻質問。四解釋應事。此初也。上既即生非生是真身。此明不生能生是應身。國土亦然。故佛示其生沒也。

At that time the Buddha told Śāriputra: "There is a land named Abhirati; the Buddha is named Akṣobhya. This Vimalakīrti passed away from that land to come and be born here." / Below, the second part clarifies the response body and response land, in two sections: first, discussing response matters; second, manifesting the body and land. The previous text has four parts: first, the Buddha reveals the name of the land; second, Śāriputra generates doubt; third, questioning by means of a metaphor; fourth, explaining response matters. This is the first. Since above, identifying birth as non-birth is the true body, here clarifying that not being born one can be born is the response body. The land is also like this; hence the Buddha reveals his passing away and being born.
