1) India is a diverse country with many languages, religions, and customs. This diversity poses challenges for national integration and unity.
2) National integration requires both political unity and an emotional sense of shared identity among citizens. It means citizens prioritize the interests of the nation over personal or regional interests.
3) Factors like linguisticism, regionalism, communalism, casteism, and socioeconomic inequalities have hampered national integration in India. Education must play a key role in fostering national integration by promoting secularism, democracy, and a shared sense of national identity and heritage.
