仁王經疏 3.220

3.220

釋曰：第二、擇滅無為。謂緣真如滅一切煩惱等相，所顯真如為擇滅無為。此有三名：一者擇滅。體即是智。擇謂簡擇，擇所得滅，故名擇滅。二數緣滅。數謂慧數，慧數所得，名數緣滅。三智緣滅，擇之與智其義一也。

Commentary: Second, the analytical-cessation unconditioned. That is, taking tathatā as an object to extinguish all characteristics of afflictions and the like, the tathatā thereby revealed is the analytical-cessation unconditioned. This has three names: first, analytical cessation (pratisaṃkhyā-nirodha). Its substance is itself wisdom. "Pratisaṃkhyā" means discrimination, and because it is the cessation attained through discrimination, it is called analytical cessation. Second, cessation through mental deliberation (saṃkhyā-nirodha). "Saṃkhyā" refers to the mental factor of wisdom; that which is attained by the mental factor of wisdom is called cessation through mental deliberation. Third, cessation through wisdom; "analytical" and "wisdom" are identical in meaning.
