瑜伽師地論略纂 8.116

8.116

論「若唯依身而息轉」等者，此中意，難非唯依身而息得轉。如入無心定等時，身在下界，而彼息不轉，故非唯依身而息得轉。

Regarding the treatise's statement, "If the breath moved depending solely on the body," and so forth: the meaning here is to pose an objection that the breath cannot move depending solely on the body. For example, when entering the mindless concentration and the like, the body is in the lower realm, yet that breath does not move; therefore, it is not solely depending on the body that the breath can move.
