成唯識論述記 5.400

5.400

述曰：自下第二，顯因果位相應多少。若在因位，同前諸師所說多少。此第七識已轉依位，與二十一心所俱生，如第八識已轉依位說。亦如彼唯捨受俱，任運而轉，曾不易脫，不分別生，六識可然。雖初地以去有行不行；成佛已去無不行時，據此義故亦名無動搖，故唯捨受。又復此智多起平等，平等即大悲等，佛位多勝，功德相應在第四禪，故唯捨受。又設下地有平等智，不變異故，如在因位唯捨受俱。若在十地隨第六識所引何地，乃至有頂，皆有此智，依彼地心法空智引入滅定時，彼地有故，不可定說下地第七為有頂依，雖通諸地皆唯捨受，此義應思，不可以因數難，彼心所法未必皆似故。恒於所緣平等轉故，唯捨受俱，諸善心所法爾作用，有二十一心所俱起。

The Commentary states: The second part below shows the number of associated factors in the causal and fruition states. In the causal state, the number is as explained above by the various masters. When this seventh consciousness has transformed its basis, it arises together with twenty-one mental factors, as explained regarding the eighth consciousness when its basis has been transformed. It is also, like the eighth, associated only with equanimous feeling, operating spontaneously, never shifting or disengaging, and not arising through conceptual discrimination—which is true of the six consciousnesses. Although from the first bhūmi onward it operates at some times and does not operate at others, once Buddhahood is attained there is no time when it does not operate; based on this meaning, it is also called "unshakable," and thus is associated only with equanimous feeling. Furthermore, this wisdom mostly gives rise to equality, and equality is great compassion and so forth; the Buddha state is overwhelmingly superior, and its associated qualities abide in the fourth dhyāna, and thus it is associated only with equanimous feeling. Moreover, even if lower bhūmis possess the wisdom of equality, because it does not vary, it is associated only with equanimous feeling just as in the causal state. In the ten bhūmis, depending on whichever bhūmi the sixth consciousness induces, up to the peak of existence, this wisdom is present in all of them; when the wisdom of the emptiness of dharmas based on the mind of that bhūmi induces entry into the cessation attainment, it is present in that bhūmi, so one cannot definitively state that the seventh consciousness of a lower bhūmi serves as the basis for the peak of existence. Although it is common to all bhūmis, it is associated only with equanimous feeling. This point should be considered: one must not object on the basis of causal numbers, because those mental factors are not necessarily identical. Because it constantly operates with equality toward its intentional object, it is associated only with equanimous feeling; by the inherent functioning of all wholesome mental factors, twenty-one mental factors arise together [with it].
