俱舍論記 2.83

2.83

「飲食資助至防援內城」者，釋所長養，長小令大、養瘦令肥。諸有礙法極微所成，名所長養。一飲食；二資助，謂塗油等；三睡眠；四等持，謂定。此四勝緣是能長養。由緣所益眼等體增，眼等增時名所長養。有雜心師說：持戒、梵行亦能長養。論主破言：此唯無損，非別有益所長養體。異熟色劣，無異熟生離所長養，故恒長養護持，長養色勝。有離異熟生，如無眼、耳修得眼、耳。故《婆沙》云「無異熟生眼離長養眼，如人重人、如壚重壚，長養防護異熟亦爾。然有長養眼離異熟生眼，如從無眼得天眼者。」問：長養通非情不？解云：不通。難：如穀麥等：雖無飲食、睡眠、等持所益，而有糞等資助所益。如何長養不通非情？解云：若汎言長養，亦通非情，糞、水等緣能長養故。此中言長養者，唯是有情勝緣所益。外法非情，非勝緣益，不名長養。

"Nourished by food and drink […] defending the inner citadel": this explains "nutritively developed"—causing the small to grow large and the thin to become plump. All obstructive dharmas formed of atomic particles are called "nutritively developed". The first is food and drink; the second is support, namely anointing with oil and the like; the third is sleep; the fourth is equipoise (samādhi). These four superior conditions are what can develop [the body]. Due to the benefit from these conditions, the substance of the eye and so forth increases; when the eye and so forth increase, they are called "nutritively developed". A master of the Saṃyuktābhidharmahṛdaya said: keeping the precepts and celibacy (brahmacarya) can also develop [the body]. The author of the treatise refutes this, saying: these merely involve no damage, but do not provide an additional benefit to the substance of the developed [body]. Ripening-born matter is inferior; there is no ripening-born [matter] apart from the nutritively developed, so it is constantly protected and supported by the nutritively developed; the developed matter is superior. There can be [nutritively developed matter] apart from the ripening-born, as when one who lacks eyes or ears obtains eyes or ears through cultivation. Thus the Mahāvibhāṣā states: "There is no ripening-born eye apart from the nutritively developed eye—just as a person carries a person or a pot stands on a pot, so too does the nutritively developed protect the ripening-born. Yet there is a nutritively developed eye apart from the ripening-born eye, as when one who lacks an eye obtains the divine eye." Question: Does nutritive development apply to non-sentient things? Answer: It does not. Objection: Such things as grains and wheat, although not benefited by food, drink, sleep, and equipoise, are benefited by the support of manure and the like; how can nutritive development not apply to non-sentient things? Answer: If speaking of development in general, it also applies to non-sentient things, because conditions such as manure and water can develop them. But what is called "nutritively developed" here refers only to what is benefited by the superior conditions of sentient beings. External, non-sentient dharmas are not benefited by superior conditions and are not called "nutritively developed".
