成唯識論述記 7.214

7.214

述曰：下長行中，文分為二：初正解頌文；後是故八識一切有情下，總料簡前三種能變。初中有三：初解所依；次五識者下，解俱、不俱相；後由五轉識下，解起、滅分位。此即初也。「根本識」者，阿陀那識，以與染、淨識為依故。淨即無漏，至二乘、菩薩等位通故。言阿賴耶者，位便局故，言根本者，生之由始，義同大眾部根本識也。解第一句下三字訖却解上二字。

[The Commentary states:] In the prose below, the text is divided into two parts: first, formally explaining the text of the verse; and second, from 'Therefore, the eight consciousnesses of all sentient beings' downward, summarizing and assessing the three preceding transformations. In the first part there are three sections: first, explaining the support; next, from 'as for the five consciousnesses' downward, explaining the characteristics of being together and not together; and finally, from 'due to the five evolving consciousnesses' downward, explaining the states of arising and cessation. This is the first section. 'Root consciousness' refers to the ādānavijñāna, because it serves as the support for both defiled and pure consciousnesses. Purity refers to the undefiled, which extends universally to the stages of the two vehicles, bodhisattvas, and so forth. If one were to call it ālayavijñāna, its stage would be too narrow. It is called 'root' because it is the origin and cause of arising, its meaning being identical to the root consciousness of the Mahāsāṃghika school. Having finished explaining the lower three characters of the first line, it now explains the upper two characters.
