俱舍論疏 28.62

28.62

The Śāstra says: "If you say that the sūtra states [...] there is no such fault." This cites two sūtras used as a rescue argument. Because there is a sūtra stating that a certain class of devas transcends solid nutriment, one knows that the form and formless realms lack solid nutriment. "Furthermore, the sūtra states that those devas take joy as nutriment; therefore, there is no fault of the upper two realms having solid nutriment"—this expresses the Mahāsāṃghika's intention: although the previously cited text had no qualification, these two distinct texts have qualifications, and therefore one knows that the upper two realms definitely lack solid nutriment.
