While the Baháʼí writings talk about the unity of the world and its peoples, unity is not equated to uniformity, but instead the Baháʼí writings affirm the value of cultural, national and individual diversity through the principle of "Unity in diversity," which states that while recognizing the unity of mankind, cultural diversity should be celebrated. Unity in diversity is commonly described in the Baháʼí writings through the analogy of flowers of one garden, where the different colours of the flowers add to the beauty of the garden.
