成唯識論述記 2.19

2.19

The Commentary states: The formal inference here is: 'The posited atoms should be susceptible to analysis, and should not be substantially real; because they possess spatial parts; like coarse matter and the like.' These two formal inferences refute the Sautrāntika masters and all who posit that atoms have spatial parts. However, the direction is itself the part, and there is no part beyond it. The Viṃśikā says: 'If an atom has spatial parts, logically it cannot be a single unity.'
