The document discusses unity and diversity in India. It states that India is described as a "unity in diversity" country because it contains a wide variety of people from different religions, languages, traditions, castes, etc. Although there are these differences, the people of India live together in peace and harmony under one central authority. Some of the key aspects that contribute to unity in diversity in India include having one Prime Minister and central government, the majority practice of Hinduism along with other religions, celebration of shared festivals and cultural events, and Sanskrit maintaining influence despite other languages being spoken.
