成唯識論掌中樞要 1.26

1.26

Answer: It takes its name from what is clarified at the beginning, because those [phenomena] depend on what is transformed by consciousness, as in the Yogācārabhūmi-śāstra. Again, it takes its name from the first two sections, because the middle section also contains the word 'vijñapti-mātra', namely, the transformation of these consciousnesses, and so forth. Or it takes its name from what is clarified at the beginning, middle, and end, because the third section says: 'Until one has not yet aroused the consciousness that seeks to abide in the nature of vijñapti-mātra,' and so forth. Or it is because the later two sections intend to explain the brief initial indication. Or, although what is clarified extends to all dharmas, there is none that is not vijñapti-mātra; therefore it is not named after anything else. Furthermore, it is because its fundamental purpose is to establish the meaning of vijñapti-mātra. Such is the main import of establishing the name 'Cheng weishi' above.
