India is the birth place of Hinduism, Buddhism, Jainism and Sikhism, collectively known as Indian religions. Indian religions, also known as Dharmic religions are a major form of world religions along with Abrahamic ones. Today, Hinduism and Buddhism are the world’s third- and fourth-largest religions respectively, with over 2 billion followers altogether, and possibly as many as 2.5 or 2.6 billion followers. India is also the birthplace for the Sikh, Jain, Lingayat, and Ahmadiyya faiths.
India is one of the most religiously diverse nations in the world, with some of the most deeply religious societies and cultures. Religion still plays a central and definitive role in the life of most of its people.
The religion of 80% of the people is Hinduism. Islam is practiced by around 13% of all Indians. Sikhism, Jainism and especially Buddhism are influential not only in India but across the world. Christianity, Zoroastrianism, Judaism and the Bahá’í Faith are also influential but their numbers are smaller. Despite the strong role of religion in Indian life, atheism and agnostics also have visible influence along with a self-ascribed tolerance to other people.
