唯識二十論述記 2.87

2.87

The Commentary says: Explaining the first half of the verse, this objects to having spatial divisions, primarily refuting the Sautrāntikas, and also hypothetically warding off the Sarvāstivādins. Now, by force of reasoning, [the paramāṇu] is forced to conjoin and possess spatial divisions; this is not their original tenet. For example, regarding the central paramāṇu of an aṇu-form, the parts facing the six directions are all distinct; since this single [paramāṇu] facing them becomes manifold in essence, how could it be a unity? Because it can be divided, as was already objected to previously. Conjoining with six paramāṇus causes it to form six parts; hence this uses having parts to refute unity as the hetu. An anumāna should be formulated: 'The posited paramāṇu should not be a unity; because it is necessarily further divisible and has spatial divisions; just like aggregate forms.' If paramāṇus do not conjoin, but can only be contiguous without multiple parts, then the central paramāṇu, although not conjoined, has a place directed toward the east that is not the place directed toward the west, and so forth; since the six facets are distinct, it must again form six and cannot be a unity. 'The posited paramāṇu should not be a unity; because the place directed toward the east is not the west and so on; like aggregate forms lacking spatial divisions.' If the direction facing east were not east, then facing west and so on would also not be west and so on. If so, this paramāṇu should not be form (rūpa), because its east, west, and so forth cannot be indicated, just like the mind and mental factors. The *Cheng weishi lun* says: 'Furthermore, paramāṇus, according to where they reside, must have differences of up, down, and the four directions; otherwise, there would be no meaning of combined aggregation (saṃghāta).' 'Combined' refutes the ancient Sarvāstivādins; 'aggregation' refutes the new Sarvāstivādin Nyāyānusāra masters. Furthermore, possessing spatial divisions necessarily entails being divisible, and hence it is not real existence.
