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.
Indian religions
Hinduism, Buddhism, Jainism and Sikhism share certain key concepts, which are interpreted differently by different groups and individuals. Until the 19th century, adherents of those various religions did not tend to label themselves as in opposition to each other, but "perceived themselves as belonging to the same extended cultural family."
