I think that there is a deep and problematic misunderstanding regarding the idea of something being "higher" or "more advanced". We usually mean these words to imply something being "better" in the ethical, moral sense along with it just being an additional skill you've developed - and of course, the other being worse by comparison.
This is simply a halo effect, and it's good to be aware of it. I think that many "authentic tantrikas" do fall for that, and I think that it is one of the most basic mistakes most religions make, to assume that the "higher", which is often associated with the spritual, the non-material, the "heavenly", stands on a higher ethical ground by definition.
It doesn't. It simply doesn't. "Your body is divine" can be a way of saying that you have to stick to certain rules in order to deal with your body in a "godly" way - I personally much prefer it to be a way of saying that your body is, by definition, something to be cherished and enjoyed, regardless of your looks, your intellect, your way of life, your moral and ethical positions, your philosophy, your... whatever, really.
