瑜伽師地論略纂 3.16

3.16

有障無障者，謂果不顯時，為有障體生故為障，而果不顯；為無障體而為障彼，故果不顯？　難無障體，量云：無體應不能為障，以無體故，如石女兒。　或汝果法應本已顯，無障緣故，如汝因法。

"Having obstruction or lacking obstruction" means: when the effect is not manifested, does an obstructive substance arise so that it acts as an obstruction and the effect is not manifested, or does it lack an obstructive substance yet obstruct it, so that the effect is not manifested? Challenging the lack of an obstructive substance, the inference states: "What lacks substance should be incapable of acting as an obstruction; because it lacks substance; like the son of a barren woman." Alternatively: "Your effect-dharma should originally already be manifested; because it lacks obstructive conditions; like your cause-dharma."
