瑜伽師地論略纂 8.47

8.47

「又不應搖身、搖臂、搖頭」等下，至「端嚴而坐」以來，總明屈申二法。此中但判不應，不明應事，准上作之。

From "furthermore, one should not shake the body, shake the arms, shake the head" and so forth below, down to "sitting upright and dignified," it comprehensively clarifies the two practices of bending and stretching. Here it only determines what is not proper and does not clarify what is proper; one should deduce it by following what precedes.
