This document discusses national integration in India. It begins by noting India's diversity in languages, religions, and customs among its population. It describes national integration as a sense of shared identity and solidarity among citizens that binds the country together despite these differences. Several factors that hamper integration are then analyzed, including linguism, regionalism, communalism, casteism, and socioeconomic inequalities. The role of education in fostering national integration is also discussed. Curricular programs, co-curricular activities, training in democracy and secularism, and the role of teachers are all outlined as important ways education can promote national unity and an integrated society.
