瑜伽論記 1.65

1.65

釋解五識從根立名有三義：一、眼等根是眼等識不共所依；二、親依眼等利鈍識明昧故；三、同時依必俱有故，非如意等。對法唯識云：隨根立名，具五義故。

The Commentary explains that naming the five consciousnesses based on their sense faculties has three meanings: first, the faculties such as the eye are the unshared bases of the consciousnesses such as eye-consciousness; second, they directly rely on the eye and so forth, so that the keenness or dullness of the faculties corresponds to the clarity or dimness of the consciousnesses; third, they are simultaneous bases that must coexist, unlike the mental faculty and so forth. The Abhidharmasamuccaya and Vijñaptimātratā say: 'Designating their names according to the faculties possesses five meanings.'
