金光明經文句記 3.267

3.267

二、「今更」下，引現事例。在家，例造罪時。捨家，例修懺時。若不遮斷，必須更改未有之事至於正有。

Second, from "Now again" downward, cites present examples of affairs. Being at home exemplifies the time of committing transgressions; leaving home exemplifies the time of cultivating repentance. If one does not ward off and sever it, one must change what has not yet existed so that it comes to actually exist.
