"Ideally I would spend a whole year on a freighter watching the waves. If God himself, in honour of my 60th birthday, would give me the strength and the power and the glory, now and forever, to draw a beautiful wave. But no, nothing like that. As soon as I got home I tried it, to no avail. I started spirals instead. That at least gave me something to go on. Drawing waves—those apparently shapeless, chaotic glories—is something I will have to leave to you and your (almost ex-)compatriots."

If you are asking about the text written on the pages themselves, it takes a bit more effort unless you are familiar with archaic script. I can make out some of them as guidelines on how to draw the patterns.
