18.133

釋曰：身三、口四諸不善色，是名性罪，以性罪故，名為犯戒。言遮罪者，非時食等。離犯戒及遮，俱說名戒。各有二者，此戒各有表、無表二也。

Explanation: The three bodily and four verbal kinds of unwholesome matter are called natural transgressions; because they are natural transgressions, they are called "transgressions of morality." What are called "prohibitions" are eating at improper times and the like. Being free from transgressions of morality and prohibitions are both called morality. "Each having two kinds": these moralities each have two kinds, vijñapti and avijñapti.
