成唯識論述記 9.348

9.348

述曰：為三問也。「誰」者，問能入人。五乘不同，誰能悟入？「於幾位」者，問所經位。既言悟入，幾位入也，凡經時節多少短長。「如何悟入」，問入方便。雖知唯識，如何方便而悟入也。

The Commentary states: These are the three questions. 'Who' asks about the person capable of entering: the five vehicles differ—who is capable of awakening and entering? 'Through how many stages' asks about the stages traversed: having spoken of awakening and entering, through how many stages does one enter, and how long or short is the duration traversed in all? 'In what manner awakens and enters' asks about the expedient means of entry: although knowing consciousness-only, by what expedient means does one awaken and enter?
