成唯識論述記 5.223

5.223

述曰：自下第二，廢立門也。於中有二：初廢立根本自類；後自釋妨。根本煩惱有十，此中何故唯有四耶？

The Commentary states: From here down is the second section, the approach of rejection and establishment. Therein are two parts: first, rejecting and establishing the fundamental [afflictions] among their own category; later, explaining objections on its own. The fundamental afflictions are ten; why here are there only four?
