I DO NOT WANT TO SEE THE ANSWER!

I am doing the Obel Lake thing and I have all the rocks, and they have what might be a code - does it stand for something? Am I meant to reverse it? Rearange it? FFX Hymn of Faith it?

Please don't tell me what it says, just give me pointers on how to rearange it - I don't want to go to Gamefaqs or anything because they might tell me the answer.
