瑜伽師地論略纂 3.16

3.16

"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."
