As we view the world around us, we are compelled to observe the manifold evidences of that universal fermentation which, in every continent of the globe and in every department of human life, be it religious, social, economic or political, is purging and reshaping humanity in anticipation of the Day when the wholeness of the human race will have been recognized and its unity established.
- Shoghi Effendi (‘The Unfoldment of World Civilization’)
