How far are you in Skyward Sword?

I have a question about the Ancient Cistern's "order of the temple".

How in the hell are you supposed to figure this out by just looking at the dials?  I came across that door and read the riddle on the stone slab there.  I went out and only located two of the dials (the ones on the back of the statue).  I had already made the statues hands close but hadn't discovered that those had dials once they were closed.  So I ran back to the door and started slashing for lolz and got the right combination on the fifth try.

Now, I'm a bit puzzled.  Now that I've located all four dials on the statue, how was I supposed to surmise which order they were in?  I see nothing on the any of the four dials that would denote that you slash a particular one first or second or so on.

lol @ this restropective puzzle.  This is a first.

Right after you come into the main room, if you cross the lily pads and get to the giant statue there is a stone tablet to the right of the door that explains the order. (something like: back, behind, back of the right hand, back of the left hand)
