Answer: There are no real atoms capable of generating gross matter; therefore it transforms suddenly and is not formed of atoms. Hence fascicle three of the *Yogācārabhūmi* states: Within an aggregate of matter there have never been atoms; when arising from their own seeds, they arise solely as aggregations—whether subtle, middling, or gross; moreover, matter-aggregates are not formed by the accumulation of atoms. Therefore we know that gross matter simply transforms suddenly.
