金剛經纂要刊定記 3.132

3.132

成法報身者。攝種性智至果得成報身，平等智至果得成法身。故長大者，論即云妙大。妙即報身，以萬行功德所莊嚴故。大即法身，真如實理遍一切故。

"Fulfilling the dharma and retribution bodies": when the wisdom that gathers the lineage reaches fruition, it fulfills the retribution body; when the wisdom of equality reaches fruition, it fulfills the dharmakāya. Therefore, regarding "great and large," the treatise says "wondrous and great." "Wondrous" refers to the retribution body, because it is adorned by the merits of the myriad practices. "Great" refers to the dharmakāya, because the real principle of tathatā pervades everything.
