俱舍論疏 2.78

2.78

On the text of the treatise: "Moreover, all mental factors… because they rely on mind": This is a counter-objection. If, because the sūtra speaks of the four great elements, there were no form and so forth, then when the sūtra speaks of the consciousness element, mental factors should also not exist; nor should one hold that mental factors are simply the mind itself, because the sūtra states that mental factors such as ideation and feeling rely on mind. If feeling, ideation, and so forth were simply the mind itself, why would the sūtra state that "mental factors rely on mind"?
