成唯識論述記 9.34

9.34

述曰：若有漏心有如無漏不起執者，即不應言「虛妄分別」；若不執心，名「妄分別」，即無漏心應名「虛妄分別之心」，即以此理明有漏心皆能遍計。《楞伽》、《中邊》等文，皆言八識是妄分別。

The Commentary states: If a defiled mind could, like the undefiled, not give rise to grasping, then it should not be called 'false discrimination'; if a non-grasping mind were called 'false discrimination', then the undefiled mind should also be called a 'mind of false discrimination'. Thus, by this principle, it is clarified that all defiled minds are capable of pervasive imagination. Passages in the Laṅkāvatāra-sūtra, the Madhyāntavibhāga, and elsewhere all state that the eight consciousnesses are false discrimination.
