Question

I did not fully understand Nachmanides' approach regarding Torah-level law and rabbinic law.
Does Nachmanides hold that the Sages have the power to create laws that have the status of Torah law by means of the thirteen hermeneutical principles through which the Torah is expounded, as he writes: "And we have not found that, in the view of the Sages, these principles are in this respect like something explicitly stated in the Torah, which they expound on their own reasoning. But in the case of a verbal analogy, they required an explicit tradition… And this is explained in the Talmud, where they said: A person may derive an a fortiori inference on his own, but he may not derive a verbal analogy on his own unless he received it from his teacher."
Or perhaps, even regarding the thirteen principles, according to Nachmanides some sort of tradition is required, as may be inferred from his statement: "Everything expounded in the Talmud through one of the thirteen principles is all Torah law, and it is the interpretation of the Torah that was said to Moses at Sinai…"
Thanks in advance.
