I heard the call to prayer for the first time in my life in Sarajevo. It was dusk and I had joined the Next Level Bosnia team up in the terrace of the hotel. We were all engaged in lively talk and jokes, admiring a wonderful view of the sunset when I heard it. It started from up high, or at least that was my impression, and then the rest of the mosques joined one by one in an eastern melody very much like what one might hear in a Greek orthodox church. And as the call started, everyone in our group, regardless of their faith, stopped to listen to this lonely prayer that was then joined by a second one and a third one and soon became a symphony of prayers stretching far and wide, leaving me awed and filled with a sense of unity.
