Fethullah Gülen promotes cooperation of civilizations toward a peaceful world, as opposed to a clash: “Be so tolerant that your bosom becomes wide like the ocean. Become inspired with faith and love of human beings. Let there be no troubled souls to whom you do not offer a hand and about whom you remain unconcerned.” (Fethullah Gülen, Criteria or Lights of the Way. London: Truestar.)
