俱舍論疏 10.211

10.211

論「頗有觸等至無漏觸等」，此明資益而非食。前說有食而非益也，且就不益不名為食，理實不益亦是食攝。

On the treatise's statement, "Is there contact and so forth ... uncontaminated contact and so forth?": this clarifies that which nourishes and benefits but is not food. Earlier, it was said that there is food that does not benefit; taking what does not benefit as not being called food is provisional, for in truth what does not benefit is also subsumed under food.
