瑜伽師地論略纂 15.90

15.90

論云「以多分故，易覺知故」者，謂多分，此四食。若爾，業、生豈非多分？即言易覺知，簡如覺者先業及凡夫離障雖易知，於諸念住易入，所以說此四句，謂段食入身，觸食入受，識食入意，思食入法也。四食日日易資養，所以餘非。此中，諸地獄有諸漸細風，名段食，初〈本地等尋伺地〉云無者，彼據重地獄，又難知故，所以不說。此處為正。

The treatise says: 'Because they constitute the majority and because they are easily perceived...' 'The majority' refers to these four nutriments. If so, are karma and birth not the majority? It then says 'easily perceived' to eliminate them: just as past karma of an awakened one and an ordinary person's detachment from obstacles, though easily known, are easily entered via the smṛtyupasthānas, these four phrases are spoken: namely, edible food enters the body, contact-nutriment enters feeling, consciousness-nutriment enters mind, and volition-nutriment enters dharmas. The four nutriments are easily sustaining and nourishing day by day, which is why others are not. In this context, in the hells there are gradually subtler winds called edible food; where the initial section on the 'Stage with Examination and Investigation' in the Maulī Bhūmi says there are none, that refers to the severe hells, and because they are difficult to perceive, they were not mentioned. This passage here is standard.
