2.76

Regarding 'furthermore, in the hells, up to: they are able to abide there for a long time': all the great hells have this food. Fascicle sixty-six states that there is no coarse food. What is spoken of now as subtle means that small hells also have subtle substances; because various morsel foods can only perform their function of nourishing the sense organs and so on at the time of change and decay, through this cause and condition they are able to abide for a long time. It is not as the Hīnayāna says, that when swallowing molten iron pellets, it temporarily removes hunger and thirst and is thus called food. Now, the meaning in the Mahāyāna is that the suffering of hunger and thirst is light, whereas the suffering produced by molten iron pellets and melted copper is severe; because the severe suffering displaces the light, they do not feel hunger and thirst—it does not mean that iron pellets and the like have the function of food.
