佛遺教經論疏節要 1.109

1.109

有智之人，故名智者。夫有智則能裁斷是非、分別利害。既知戒念是利而非害故，制而不隨。既知根欲是害而非利故，持之如賊。論云「此是重障」，故不令縱。下示輕障。假令縱之者，謂細相習障，縱有根欲，不作意起也。不久見其磨滅者，云何立見？示現依見時說故。譬之無常，必歸磨滅。

A person possessing wisdom is therefore called a wise person. One who has wisdom can judge right and wrong and distinguish benefit and harm. Knowing that precepts and mindfulness are beneficial and not harmful, they restrain them and do not follow them. Knowing that sense faculties and desires are harmful and not beneficial, they hold them like thieves. The treatise says: "These are heavy obstacles," and therefore one does not let them run wild. Below, light obstacles are shown. "Even if they are indulged" refers to the subtle obstacles of habitual tendencies; even if there are sense faculties and desires, they are not deliberately stirred up. As for "before long one will see them completely perish," how is seeing established? It is spoken based on the time when they are seen. By analogy to impermanence, they must inevitably return to destruction.
