The french line la lune ne garde aucune rancune translates to the moon never holds a grudge. which best describes the meaning of this line

It means that the moon has no memory of what happened previously. It rises at the end of each day to cast its pale light over a land that considers that light beautiful. The moon remembers nothing of this and does not put any particular meaning to its journey through the sky. It forgets what it has seen the night before and all the nights before the current one.
