三、了別境識，即餘六識。《二十論》說：心、意、識、了，名之差別。「了」是諸識之通名也，了別別境及麁顯境，唯前六故；對此六塵說六識故，然濫第七。應言此六了別麁境，名了別境識。以了別相麁，簡於七、八故。了別境即識，亦同前解。

Third is the consciousness that cognizes objects (viṣayavijñapti), which is the remaining six consciousnesses. The Viṃśikā states: "Citta, manas, vijñāna, and vijñapti are distinctions of name." "Cognizing" (vijñapti) is a general name for all consciousnesses; yet cognizing distinct objects and coarse, evident objects belongs only to the first six; and the six consciousnesses are posited with respect to these six sense-objects. However, this might be confused with the seventh. One should state: these six cognize coarse objects, so they are named the consciousnesses that cognize objects. Because their marks of cognition are coarse, they are distinguished from the seventh and eighth. "Cognizing objects is consciousness" is likewise identical to the preceding explanation.
