金剛經纂要刊定記 2.127

2.127

佛所立名本約堅利，如上六義乃是兼明，諸家至此多不料簡，殊濫正義。若將此六配前五因，即一當第三，二三當四五，四當第二，五六當第一。

The name established by the Buddha was originally based on hardness and sharpness. The six meanings above are secondary explanations; when various masters reach this point, they mostly do not distinguish them, which severely confuses the primary meaning. If one matches these six to the preceding five causes: the first corresponds to the third; the second and third correspond to the fourth and fifth; the fourth corresponds to the second; and the fifth and sixth correspond to the first.
