成唯識論述記 7.477

7.477

述曰：若一切凡夫已得實境，由境非妄故，即一切凡夫應不由功用，自成解脫，解脫不成，故唯有識。舊云：難塵是實有。今言證實智不成，證知唯有識。已下境隨三惠轉。

The Commentary states: If all ordinary worldlings had already attained real objects, since the objects would not be false, then all ordinary worldlings would naturally attain liberation without effort; since liberation is not attained, therefore there is consciousness-only. The old rendering states: 'Objecting that sense-objects are real.' Here we say: the wisdom realizing reality is not achieved, proving and knowing that there is consciousness-only. Below, objects transform in accordance with the three wisdoms.
