俱舍論疏 10.179

10.179

論「如是段食至生上界故」，此文第二界繫分別。《正理論》云「非上界身依外緣住，色界雖有能益大種，而非段食，如非妙欲。如色界中雖有微妙色、聲、觸境，而不引生增上貪故，不名妙欲。如是雖有最勝微妙能攝益觸，而畢竟無分段吞噉，故非段食。雖非段食攝，而非無食義。如喜雖非四食中攝，而經說為食，以有食義故。如契經言『我食喜食，由喜食久住，如極光淨天。』若爾，欲界亦應唯口分段吞噉方名段食。不爾，欲界吞噉為門，餘可相從立此名故。非於色界小有吞噉，可令餘觸從彼為名，是故二界無相類失。若人生在北俱盧洲，離段吞噉壽豈斷壞？雖不斷壞，而所依身形色疲損，苦為存活。若爾，何故彼由食住？香等為食，非要吞噉。彼定常嗅如意妙香，或觸可愛風等妙觸。又彼身中有能益煖。或非欲界皆資段食，亦非段食定唯欲界，從多就勝故作是言。下有、上無，不應為難。」

The Śāstra says: "Solid food such as this ... because of being born into higher realms." This text is the second [part], distinguishing the realm to which it is bound. The Nyāyānusāra says: "It is not that the bodies of higher realms abide dependent on external conditions. Although the form realm has primary elements that can nourish, they are not solid food, just as they are not exquisite desires. Just as in the form realm, although there are subtle and exquisite objects of visible form, sound, and touch, they do not induce intense greed, and hence are not called exquisite desires. Likewise, although there is supreme, exquisite touch that gathers and nourishes, there is definitively no swallowing by morsels; therefore, it is not solid food. Although it is not included in solid food, it is not without the meaning of food. For instance, although joy is not included among the four foods, the sūtras call it food because it has the meaning of food. As a sūtra says: 'I feed on the food of joy; by the food of joy I abide for a long time, like the Gods of Utmost Radiance (Ābhāsvara).' If that is so, then in the desire realm, too, only what is swallowed by mouthfuls in morsels should be called solid food. Not so. In the desire realm, swallowing is the entry door, and the rest can be designated by this name in accordance with it. It is not the case that there is a small amount of swallowing in the form realm such that other touch could be named after it; therefore, there is no error of false analogy between the two realms. If a person is born in Uttarakuru, could their lifespan be severed without swallowing morsels? Although it is not severed, the form and complexion of their physical basis would become exhausted and impaired, making it hard to survive. If so, why do they abide by food? Odor and so forth serve as food; swallowing is not necessary. They constantly inhale wish-fulfilling exquisite odors, or touch pleasant, gentle winds and other exquisite tangibles. Moreover, within their bodies there is nourishing warmth. Or perhaps it is not that all in the desire realm are sustained by solid food, nor that solid food is definitively restricted to the desire realm; this statement was made based on the predominant and primary. One should not object on the basis of what is present below and absent above."
