Would having only one religion increase brotherhood and end violence?

According to Osho, one world religion would not create brotherhood; it would deaden life’s rich variety and breed new forms of coercion. People are different, so there must be many paths—meditative, devotional, celebrative. Real unity is harmony-in-diversity: let each be intoxicated by their own doorway to the divine. Violence ends when we drop hurt egos, stop imposing tastes, and respect private feelings.
