西國有解，三乘無漏種子法爾性成發心已後八解脫分位及順決擇位，即就此位說此種子亦名順解脫分等，此二善根即是未知當知根體，故言三無漏根一向無漏道諦所攝。又言順解脫分通三界繫及不繫者，體是有漏是三界繫，由厭生死不定招感，名為不繫。順決擇分通色無色繫及不繫，義亦如前。

In the Western country there is an explanation: The taintless seeds of the three vehicles are naturally accomplished by their nature; after generating the mind [for awakening], in the stage of the eight aids to liberation and the stage conforming to penetration, it is precisely in reference to these stages that these seeds are also named conforming to the aids to liberation and so forth. These two wholesome roots are precisely the substance of the faculty of knowing what is not yet known; therefore it is said that the three taintless faculties are exclusively taintless and subsumed under the truth of the path. Furthermore, regarding the statement that the aids to liberation encompass being bound to the three realms and being unbound: their substance is tainted and bound to the three realms, but because they are weary of birth-and-death and do not definitely induce [rebirth], they are called unbound. That the aids to penetration encompass being bound to the form and formless realms and being unbound has the same meaning as before.
