瑜伽師地論略纂 2.116

2.116

受用有三，上明苦樂受用。第二、飲食受用，初總、後別。　「將生有情」者，謂中有。　已生有情，謂五趣有。顯出三界，不假四食。別中有二，謂界趣麁細。欲界有睡眠等，故假段食，上二界無。

Enjoyment has three kinds; the above explained the enjoyment of suffering and pleasure. Second is the enjoyment of food and drink: first in general, then in detail. "Sentient beings about to be born" refers to the intermediate existence. "Sentient beings already born" refers to existence in the five destinies. This shows that those who have transcended the three realms do not rely on the four foods. In the detailed explanation there are two points: namely, the coarse and subtle aspects according to realms and destinies. The desire realm has sleep and so forth, and therefore relies on kavaḍīkārāhāra; the upper two realms do not have it.
