金剛經纂要刊定記 6.52

6.52

共欲者。染也。欲謂五欲，即色等五塵，心與欲合故名為共。又欲謂貪欲，是心所攝，舉初該後，意兼瞋等，心與貪等相應，故云共也。前約與境相應，此約與煩惱相應，皆為染也。

Regarding "with desire": this is defilement. "Desire" refers to the five desires, namely the five dusts of form and so forth; the mind conjoining with desire is named "with [desire]." Furthermore, "desire" refers to greedy desire, which is subsumed under mental factors; mentioning the first includes the rest, meaning it encompasses anger and so forth; the mind associating with greed and so forth is therefore called "with." The former is in terms of association with sense-objects, while this is in terms of association with afflictions; both are defilement.
