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.
Hindutva
According to this, the natives of India share a common culture, history and ancestry. M. S. Golwalkar, one of the proponents of Hindutva, believed that India's diversity in terms of customs, traditions and ways of worship was its uniqueness and that this diversity was not without the strong underlying cultural basis which was essentially native. He believed that the Hindu natives with all their diversity, shared among other things "the same philosophy of life", "the same values" and "the same aspirations" which formed a strong cultural and a civilizational basis for a nation.
