The Written Torah, the Oral Torah, the commandments of the Sages . . . the Halakhah, the 'Aggadah . . . it's all Torah.
OK, to be more precise: I am talking about the subset of the overall Torah that is the 613 commands.
And getting back to the point of the article: you can theoretically not violate a mitzvah and still do something wrong (or rather, still be able to do better).
