俱舍論記 1.257

1.257

「即由如是至故別立蘊」者，前指下文，故今略顯。四義非一者，名諸次第。所以於諸行中別立受、想者，一為相麁，麁、細門也；二為生染，起過門也；三類食同助，器等門也；四二界中強，界別門也。

Regarding [the text from] “Precisely due to such [reasons] …” to “… therefore they are separately established as skandhas,” the former refers forward to the text below, so it is now briefly revealed. That the four meanings are not one is called the various sequences. The reasons why feeling and conception are separately established among formations are: first, because their characteristics are coarse, which is the aspect of coarse and subtle; second, because they generate defilement, which is the aspect of giving rise to faults; third, their similarity to food and condiments, which is the aspect of vessel and so forth; fourth, because they are strong in the two realms, which is the aspect of realm distinctions.
