金剛般若經依天親菩薩論贊略釋秦本義記卷上 1.124

1.124

經。須菩提於意云何三千大千世界所有微塵是為多不　總中第三降染故勝也。將明此義。先辨因果有其三種。一布施因果。因謂布施果謂煩惱。由取相施增煩惱故。二世界因果。因謂世界果謂微塵。由界聚相散為塵故。三持經因果。因謂持經果謂法身。由能持說證法身故。今此文中校量前二以顯後一。然經舉諸微塵等者。即世界因果。此之微塵名為色塵。體是無記。但坋色身不坋法身。非如布施所生煩惱名為法塵。能坋淨心及以法身故。今將此無記因果對彼布施染污因果。彼尚不及無記塵。因何能更方持說之福。故知施福增有因經滅惑也。今釋此文復分為二。初舉劣顯勝。後辨勝過劣。前中有二。一問二答。此初問也。三千大千世界者。舉其因也。所有微塵者。顯其果也。是為多不者。問其量也。所以問此微塵多少者。將顯染塵過於此故。

[Sūtra:] "'Subhūti, what do you think? Are all the motes of dust in a three-thousandfold great-thousandfold world-system many?'"
This is the third overall part, superiority due to overcoming defilement. To clarify this meaning, one first distinguishes causes and effects into three kinds: first, cause and effect of giving: the cause is giving and the effect is affliction, because giving through grasping at marks increases affliction; second, cause and effect of world-systems: the cause is the world-system and the effect is motes of dust, because the accumulated marks of the realm disperse into dust; third, cause and effect of upholding the sūtra: the cause is upholding the sūtra and the effect is the dharmakāya, because being able to uphold and explain it realizes the dharmakāya. Now, in this passage, the first two are compared to demonstrate the last one. Yet, when the sūtra adduces all motes of dust, etc., this is the cause and effect of world-systems. These motes of dust are termed material dust; their essence is indeterminate. They only defile the material body and do not defile the dharmakāya; they are not like the afflictions produced by giving, which are called dharma-dust and can defile the pure mind as well as the dharmakāya. Now, taking this indeterminate cause and effect and contrasting it with the defiled cause and effect of giving: the latter does not even equal the cause of indeterminate dust, so how could it compare to the merit of upholding and explaining? Thus we know that while the merit of giving increases existence, relying on the sūtra extinguishes delusion. Now, in explaining this text, it is divided again into two: first, adducing the inferior to show the superior; second, determining that the superior surpasses the inferior. Within the first, there are two: first, question; second, answer. This is the first question. "A three-thousandfold great-thousandfold world-system" adduces its cause. "All the motes of dust" shows its effect. "Are they many?" asks about its quantity. The reason for asking about the amount of these motes of dust is to show that defiled dust surpasses this.
