72.31

次依論問中有微細。一切牆壁山崖樹等皆不能礙。此彼中有為相礙耶。有作是說。此彼中有亦不相礙。以極微細。相觸身時不覺知故。復有說者。此彼中有亦互相礙。以相遇時。此彼展轉。有語言故。問若爾寧說中有無礙。答於餘無礙。非謂中有。問此彼中有皆相礙耶。答自類相礙非於餘類。謂地獄中有但礙地獄中有。乃至天中有但礙天中有。有作是說。劣礙於勝。以麁重故。勝不礙劣。以細輕故。謂地獄中有礙五中有。傍生中有礙四中有。鬼界中有礙三中有。人中有礙二中有。天中有唯礙天中有。

Next, relying on the treatise, it asks: An intermediate being is subtle; all walls, cliffs, trees, and the like cannot obstruct it. Do these intermediate beings obstruct one another? Some say: These intermediate beings also do not obstruct one another, because they are extremely subtle, and when their bodies touch one another, they do not perceive it. Others say: These intermediate beings also obstruct one another, because when they encounter each other, they speak with one another. Question: If so, how can one say that an intermediate being is unobstructed? Answer: It is unobstructed with respect to other things, not with respect to other intermediate beings. Question: Do all intermediate beings obstruct one another? Answer: Those of the same class obstruct one another, but not those of different classes. That is, a hell-destined intermediate being only obstructs another hell-destined intermediate being, and so forth up to a heaven-destined intermediate being only obstructing another heaven-destined intermediate being. Some say: The inferior obstructs the superior because it is coarse and heavy; the superior does not obstruct the inferior because it is subtle and light. That is, a hell-destined intermediate being obstructs five kinds of intermediate beings, an animal intermediate being obstructs four kinds of intermediate beings, a hungry-ghost intermediate being obstructs three kinds of intermediate beings, a human intermediate being obstructs two kinds of intermediate beings, and a heavenly intermediate being obstructs only heavenly intermediate beings.
