俱舍論疏 28.61

28.61

The Śāstra says: "Furthermore, it speaks of the four nutriments [...] there should be solid nutriment." This refutes them by drawing a parallel. The sūtra speaks of the four nutriments as being like the four stations of consciousness; since the sūtra makes no qualification, the form and formless realms should have solid nutriment, because they have the four stations of consciousness and the sūtra does not qualify it.
