Indian culture is the heritage of social norms, ethical values, traditional customs, belief systems, political systems, artifacts and technologies that originated in or are associated with the ethno-linguistically diverse Indian subcontinent. The term also applies beyond India to countries and cultures whose histories are strongly connected to India by immigration, colonization, or influence, particularly in South Asia and Southeast Asia. India's languages, religions, dance, music, architecture, food and customs differ from place to place within the country. The rich heritage of India, one of the world's oldest civilizations, is an all-embracing confluence of religions, traditions and customs. The highlights of Indian heritage lie in the treasure of its art, architecture, classical dance, music, flora and fauna, and the innate secular philosophy of its people.
