成唯識論述記 2.476

2.476

述曰：即是五識身，他心智境，謂色等五塵及心、心所，此約總聚，不別分別此何識境，現量所知，名現所知。

The Commentary states: These are the domains of the five consciousnesses and of the knowledge of others' minds (paracitta-jñāna), namely the five sensory objects such as form, as well as mind and mental factors. This is stated in terms of the aggregate as a whole, without differentiating which consciousness's object it is; being cognized through direct perception (pratyakṣa), they are called "directly cognized".
