成唯識論述記 10.536

10.536

述曰：總有四種，而今但取二所轉得，餘三轉依不可證故。設有真如及無漏道，不是證義故不說之。

The Commentary states: In total there are four kinds, but now we only take the two that are obtained through transformation, because the other three transformations of the basis cannot be realized. Even if there are tathatā and the anāsrava path, they are not in the sense of realization, and so they are not spoken of.
