I tried Zen and Ching, numerology, tarot cards and astrology. I tried to look back into the Bible, and could not find anything. At this time I did not know anything about Islam, and then, what I regarded as a miracle occurred. My brother had visited the mosque in Jerusalem, and was greatly impressed that while on the one hand it throbbed with life.

Not only did the terrorists hijack planes and destroy life, but they also hijacked the peaceful religion of Islam and split the brother and sisterhood of mankind.

In the early days I had a very black-and-white view of everything. I think that's kind of natural for anyone who's just embraced Islam - or any religion - as a convert. It was important for me to duck out of the fast and furious life I'd been living as a pop star. I was in a different mood.

I had to learn my faith and look after my family, and I had to make priorities. But now I've done it all and there's a little space for me to fill in the universe of music again.

'Peace Train' is a song I wrote, the message of which continues to breeze thunderously through the hearts of millions. There is a powerful need for people to feel that gust of hope rise up again.

All the songs that were written for that album are just all our first sophomore songs. So they're all from real life. Very sweet and very innocent. I think the theme of the album probably was just that it was our first record. ... Back when we were first making records, you didn't just make the music, you put a great deal of energy into the way it looked, and every word that was written on the whole thing.

The spiritual quest was always the predominant aspect of my life. It's always been there. But there's also an incredible passion connected to it; it's not just a dry investigative process. I have been extremely emotional about it, and that comes out in the songs.
