2.101

Commentary: Previously it was refuted that lacking parts would mean they cannot obstruct each other; now it is refuted that if they do not obstruct each other, their locations should be identical. The location of this paramāṇu should be precisely the location of all the paramāṇus, because they do not obstruct each other. If so, this form could not become coarse, because they would all interpenetrate.
