What bothers me is that the blank papers are there.. I though Akasha wrote on them and had them in her possession. >_> Also, as far as I can see, there are two large pyramids stacked upon each other, not just one floating in the air.

I like what phrog said.. it also made me think about convection currents. In the first place, what do we know about the fire? Maybe it doesn't consume at all, as it constantly burns without any apparent energy source.
If you don't want to risk your own body, try the papers first; if the fire heats the air enough, the papers should float up high to touch the pyramids. I dunno, magic words might appear on them. In any case, they reappeared even though Akasha took them, so even if they are burned by the fire, who's to say they won't be in the shrines once again when you look? They're useless at this point, so experiment!
MD also has this cube-theme going on. Going from Robins's theory, you could try make a cube out of the pyramids on the ground, if possible. I'd like to imagine the two floating pyramids rotating to align and make a cube, activating something.
This is the first time I've heard something about shrines in the pyramids (Akasha! Why didn't she tell us? Did something change since she was there?).. Since there's a paper for each one, it sorts of makes me think you're supposed to write something to go on each and then put them in the corresponding shrine/pyramid. I don't know how you'd decide, though. People seem to think it's related to the principles, which could be, but there's only 7 shrines and yet 10 principles.
... back to homework. D:
