成唯識論述記 2.672

2.672

述曰：下別顯有三：初顯不依真，唯依共相轉，即此真事，非謂心外實體名「真」，但心所取法自體相，言說不及，假智緣不著，說之為真，此唯現量知，性離言說及智分別。此出真體非智、詮及。

The Commentary states: Below, the specific elucidation has three parts: first, showing that it does not rely on the real, but operates solely based on the common characteristic (sāmānyalakṣaṇa). That is, this 'real entity' does not refer to a real substance external to the mind being called 'real'; rather, it is just the self-characteristic of dharmas apprehended by the mind, which words cannot reach and conventional cognition cannot grasp as an object, that is called 'real'. This is known solely by direct perception (pratyakṣa), its nature being free from verbal expression and conceptual discrimination of cognition. This brings out that the real substance is beyond the reach of cognition and designation.
