金剛般若波羅蜜經註解 1.272

1.272

此釋微塵，喻應身無異性。若知碎世界作微塵，微塵全是世界，則塵無實性，故曰則非微塵；以離性計而說微塵，故曰是名微塵也。此喻全法起應，應即是法，何異性之有哉？

This explains the dust motes, illustrating by metaphor that the nirmāṇakāya has no separate nature. If one knows that smashing the world into dust motes means the dust motes are completely the world, then dust has no real nature; hence it is said, "then it is not dust motes." Because it is spoken of as dust motes while free from the conceptual imputation of intrinsic nature, it is said: "it is named dust motes." This illustrates that the entire dharma gives rise to the response, and the response is identical to the dharma; how could there be any separate nature?
