瑜伽師地論略纂 1.47

1.47

等無間依，《唯識》三說。一云第六識以前六識為依，七、八唯以自類為依；二云第六意識用前自類或第七、八為開導依，七以自類、第六為依，第八以自類及第六、七為開導依；三云六、七、八識各以自類為開導依，最為中理。三釋雖別，並不違此文。

Regarding the immediately preceding support, there are three explanations in the *Cheng weishi lun*. The first says that the sixth consciousness takes the preceding six consciousnesses as its support, while the seventh and eighth take only their own categories as their support. The second says that the sixth, manovijñāna, uses the preceding of its own category or the seventh and eighth as its opening and guiding support; the seventh takes its own category and the sixth as its support; and the eighth takes its own category as well as the sixth and seventh as its opening and guiding support. The third says that the sixth, seventh, and eighth consciousnesses each take their own category as their opening and guiding support, which best accords with reason. Although the three explanations differ, none contradicts this text.
