俱舍論記 4.6

4.6

Regarding 'The treatise says [...] without subtraction of any one': within the prose commentary, [there are]: first, explaining the verse text; second, incidentally explaining the higher realms; third, differentiating through questions and answers; fourth, putting an end to disputes. Within explaining the verse text, [there are]: first, the direct explanation; second, explaining external objections. Below this is the direct explanation, which explains the first two lines. In the desire realm (kāma-dhātu), the aggregation of matter that is extremely subtle, lacking sound and lacking faculties, such as external mountains and rivers, still has eight [entities] arising together without the reduction of any one, establishing the name 'subtle aggregation' (aṇu-saṃghāta / saṃghāta-paramāṇu) to indicate that there is nothing subtler than this. The term 'subtle aggregation' indicates an aggregation that is subtle and minute; that is, the minimal, subtle aggregation among aggregations of matter is called a 'subtle aggregation'. That is to say, the subtlety itself is an aggregation; it is not that a single atomic particle (paramāṇu) is called a 'subtle aggregation'. Furthermore, the tenth fascicle of the Nyāyānusāra states: 'Such numerous atoms intimately combining and definitely not separating from one another is termed an atomic aggregation (that treatise names it atomic aggregation because it is an aggregation of atoms. Each relies on one perspective, and they do not contradict each other).' It should be understood that there are two kinds of atoms: first, the material aggregation atom, which is the minimal eight entities arising together that cannot be reduced, which is what this treatise relies on in its explanation; second, the ultimate atomic particle (paramāṇu), which is the extreme minimum of matter that can no longer be divided, which is what the Nyāyānusāra relies on in its explanation.
