俱舍論疏 2.233

2.233

論「應言此四或異或同」，總答。今詳三法若與身俱名同，不與身俱名異。故《正理》云「所言同者，謂生欲界，以自地眼見自地色，四皆同地。生初靜慮，以自地眼見自地色，亦皆同地。所言異者（云云）。餘句准此。二地四法，同地名之為同，自餘諸句皆是異也。身生欲界有一句同，餘句皆異。生初靜慮有一句同，餘句皆異。二、三、四定唯是異句，無其同句，以於上地無五識故，耳亦如是。鼻、舌二種唯有同句，無有異句，二境二識唯欲界故，上地有根無識依故，身在下地無上根故。身根若生欲界及初靜慮唯有同句，生上三地唯有別句。意根若四蘊身，隨生何地皆有同句、異句，若初約色身，唯在五地。辨其同、異，如理應思。」言「上至餘界亦應如是分別」，是指法以明也。

On the Śāstra's: "One should say that these four are either different or identical": The general answer. Now examining this: if the three dharmas are in the same plane as the body, they are called "identical"; if they are not in the same plane as the body, they are called "different." Therefore the Nyāyānusāra states: "What is called 'identical' means that one born in the desire realm sees visual forms of one's own plane with an eye of one's own plane; all four are of the identical plane. One born in the first dhyāna sees visual forms of one's own plane with an eye of one's own plane; all are likewise of the identical plane. What is called 'different' (and so forth). The remaining permutations are to be inferred from this. When the four dharmas across two planes belong to the same plane, they are called 'identical'; all the other permutations are 'different.' For a body born in the desire realm, there is one identical permutation, and the remaining permutations are all different. For one born in the first dhyāna, there is one identical permutation, and the remaining permutations are all different. In the second, third, and fourth dhyānas, there are only different permutations and no identical permutation, because in the higher planes the five consciousnesses do not exist; the ear is likewise. The two—nose and tongue—have only identical permutations and no different permutations, because their two objects and two consciousnesses belong solely to the desire realm, and while the higher planes have the faculties, they lack the supports for consciousness, and a body in a lower plane cannot possess higher faculties. As for the body faculty, if born in the desire realm or the first dhyāna, there are only identical permutations; if born in the higher three planes, there are only distinct permutations. As for the mental faculty, if it is a body of the four skandhas, no matter which plane one is born in, there are both identical and different permutations; if initially considered with respect to the physical body, it exists only in the five planes. Discriminating their identity and difference should be contemplated in accordance with reason." The statement "Up to the other realms, they should also be distinguished in this way" indicates the principle to explain it.
