文答雖由如是七種因緣諸行得住至令行相續而住者，此即總答。且如段食，或有食根藥華菓泥石火䥫等，由種種門令行得住，由段食故識食悅，識食悅故增喜樂，喜樂相應觸為觸食，思為思食，是故四食皆由種種門令諸行住。又此四食，如次攝受別義。一、氣力；二、喜樂；三、於可愛境專注希望；四、即三所依諸根大種及壽竝煖安住不壞。

From the text's reply, "Although conditioned things abide due to such seven conditions..." up to "causing conditioned things to abide in continuity": this is the general reply. Take material food for example: there may be eating of roots, medicines, flowers, fruits, mud, stones, fire, iron, and so forth, which causes conditioned things to abide through various gates. Due to material food, consciousness as food is gladdened; because consciousness as food is gladdened, joy and pleasure increase; contact associated with joy and pleasure is contact as food, and volition is mental volition as food; therefore all four nutritions cause conditioned things to abide through various gates. Furthermore, these four nutritions respectively appropriate distinct meanings: first, physical energy; second, joy and pleasure; third, focused hope regarding desirable objects; fourth, the various faculties, great elements, lifespan, and warmth—which serve as the basis for the [previous] three—abiding peacefully without disintegrating.
