首楞嚴義疏注經 7.4

7.4

戒是正順解脫之本，依因此戒得有定慧，故知三昧戒為先容。此之重禁雖約身口，一一治心。既與定慧相應，色香味觸無非實相，豈有魔事惱亂行者？

Precepts are the root that properly accords with liberation; relying on these precepts, one attains concentration and wisdom. Therefore, we know that for samādhi, precepts serve as the preliminary reception. Although these grave prohibitions are framed in terms of body and speech, each and every one cures the mind. Once they accord with concentration and wisdom, sights, sounds, scents, tastes, and tangibles are nothing but the real mark; how could there be demonic affairs troubling the practitioner?
