You just learn new ways to put that feeling across. During the making of Mysteries, I went through a lot of heavy mental phases, and my lyrics at that time where heavily influenced by that. As time passed I read a lot of stuff like Ayn Rand, Carlos Castaneda, Robert M. Prisig and Albert Camus. All of them were pure revelations to me. On my website I've listed several works that have been of crucial importance to me.
Literature is very important.
I am currently reading The Silmarilion by J.R.R. Tolkien. I read The Hobbit and The Lord Of The Rings years ago, and it feels good to be back in that world again. It stirs the imagination, which is always very positive. But in the end, this is all about exploring- and dealing with totally abstract things. Lyrically too, although my lyrics are often small stories or poems that get dotted down in the heat of some weird or sad situation.
