瑜伽師地論略纂 14.47

14.47

論云「餘長養流當知亦由食故」者，即前食；「彼所依故」，即睡眠、梵行；「修勝作意故」者，即定也。

The treatise says: "The remaining nourishing flow should be known to be also due to food"—that is, the aforementioned food; "due to its basis"—that is, sleep and celibacy (brahmacarya); "due to cultivating superior attention (manaskāra)"—that is, concentration.
