金剛般若經依天親菩薩論贊略釋秦本義記卷上 1.126

1.126

經。須菩提諸微塵如來說非微塵是名微塵　第二辨勝過劣也。文復有二。初約果辨。後約因辨。此即初也。諸微塵者。謂世界無記塵也。如來說非微塵者。謂非如施福所生染煩惱塵也。是名微塵者。是地等之微塵也。

[Sūtra:] "'Subhūti, all motes of dust the Tathāgata speaks of as non-motes of dust; these are named motes of dust.'"
This is the second [part], determining that the superior surpasses the inferior. The text again has two parts: first, determining in terms of effect; second, determining in terms of cause. This is the first. "All motes of dust" refers to the indeterminate dust of the world-system. "The Tathāgata speaks of as non-motes of dust" means they are not like the defiled dust of affliction produced by the merit of giving. "These are named motes of dust" means they are the motes of dust of earth and the other [elements].
