Welllllll, this should be in the Z:TP sub-forum by the way but no worries.
We don't really know where abouts in the temple you are at the moment (logically, and pretty much right from commeon sense for those who've played, you're in the first dungeon, si?)
Spoiler Alert!This might not be a spoiler... we'll find out: But you need to fight a sub-boss who looks like a white baboon that has the Gale boomerang. I thought the path of the temple is pretty linear to his domain, but I can't really remember much about the first temple, sorry that this won't be much help at all...
But you can look online via Google for a Zelda: Twilight Princess Walkthrough.
