唯識二十論述記 2.48

2.48

述曰：此釋下二句頌。若言極微無方分故，不相合者，中間極微既與六合時，既應互相糅同一處所。中一微處，既與六微，同處而住，應阿耨等諸麁聚色，如極微量，更不增長，即微處故。

Commentary: This explains the lower two lines of the verse. If it is said that because atoms have no spatial divisions they do not conjoin with each other, then when the middle atom conjoins with the six, they should mutually merge and occupy one and the same location. Since the six atoms abide in the same place as the one atom in the middle, all coarse aggregate forms such as the aṇu should be equal to the dimension of an atom, without any increase, because they occupy the very same location as the atom.
