成唯識論述記 4.150

4.150

述曰：《攝論》亦同。摩訶僧祇名大眾部，釋此部等名如《宗輪》記，於此部中名根本識，是諸識所依止故。非六轉識可名根本，不能發起六轉識故，其喻可知。阿笈摩者，此翻為教，展轉傳說故名為傳。唯第八識有如是義，結喻可知。

The Commentary states: The *Mahāyānasaṃgraha* is also the same. *Mahāsāṃghika* is translated as the Great Assembly School; the explanation of the names of this school and others is as in the commentary on the *Samayabhedoparacanacakra*. In this school it is called the 'root consciousness' (*mūlavijñāna*), because it is that upon which all consciousnesses depend. It is not possible for the six transitioning consciousnesses to be called the root, because they cannot generate the six transitioning consciousnesses; the metaphor for this is clear. *Āgama* is translated here as 'teaching'; because it is passed down through successive transmission, it is called a tradition. Only the eighth consciousness possesses such a meaning; concluding with the metaphor, it is clear.
