Religion in India
Religion in India is characterised by a diversity of religious beliefs and practices. India is a secular state with no state religion. The Indian subcontinent is the birthplace of four of the world's major religions; namely Hinduism, Buddhism, Jainism and Sikhism. Throughout India's history, religion has been an important part of the country's culture. Religious diversity and religious tolerance are both established in the country by the law and custom; the Constitution of India has declared the right to freedom of religion to be a fundamental right.
Dravidian folk religion
Scholars regard Indian religions as a fusion or synthesis of various Indian cultures and traditions.
Among its roots are the historical Vedic religion of Iron Age India, itself already the product of "a composite of the indo-Aryan and Harappan cultures and civilizations", but also the Sramana or renouncer traditions of northeast India, and mesolithic and neolithic cultures of India, such as the religions of the Indus Valley Civilisation, Dravidian traditions, and the local traditions and tribal religions.
