Rather hard to know exactly what we're looking at here. If I were to take a guess, you're smack in the middle of a big room looking at a big, locked door, right?
There should be a wall you can break in that big room, which leads to a switch. The switch controls three doors in the big room. Every time you push the switch, one door will close, and a new one will open. Inside the three rooms the switch leads to, you'll find a wheel that you must turn. Also, in one of them you have to look to your left and shoot down a big bridge.
Once you have turned three wheels, the big door is open.
Of course, I might think this is a different temple than it is, so do correct me if I'm talking about the wrong place. I haven't used the maps inside the temples a whole lot.
