The Gemara in Shabbos 21b famously writes "Mai Chanukah"- what is Chanukah? The Gemara elaborates:
When the Greeks entered the Sanctuary they defiled all the oils that were in the Sanctuary
While it is a true matter that they could've used impure oil for lighting the menorah, they insisted in using pure oil, but that is not the question here.
I was wondering, since I've read so many times past it, how exactly did the Greek make the oil impure?
Explanations I read:
Chassidus (Lubavitch) explains that they made the oil impure by fighting a spiritual war against the Torah-intellect from the Jewish people. They tried to uproot the Torah. And since oil represents the inner dimension of Torah, this is one of the explanations.
The Greeks, as gentiles, carried the oil, and thus transforming it into impure.
I am looking for other explanations on how exactly the Greek made the menorah-oil impure.
