The game isn't exactly linear, so if you're where I think you are... you won't be able to do anything there yet. There IS an exit close by, if you are where I think you are, and all you have to do is go swim to it and eventually you'll see a big red flower (remember that for later) and around there is the exit, which will take you back to a place you have already been that is close to the main entrance/exit to the place. If you can't do something right away, make a note of it, and see if you can get out so you can obtain whatever you need to have to be able to do those things. Sounds like you're done with the energy temple, and you just need to go to a new area of the game for a while. Sorry if that is vague, but trying not to give TOO many spoilers.... heh.
