Hinduism is the religion of the majority of people in India and Nepal. It also exists among significant populations outside of the sub continent and has over 900 million adherents worldwide.
In some ways Hinduism is the oldest living religion in the world, or at least elements within it stretch back many thousands of years. Yet Hinduism resists easy definition partly because of the vast array of practices and beliefs found within it. It is also closely associated conceptually and historically with the other Indian religions Jainism, Buddhism and Sikhism.
Unlike most other religions, Hinduism has no single founder, no single scripture, and no commonly agreed set of teachings. Throughout its extensive history, there have been many key figures teaching different philosophies and writing numerous holy books. For these reasons, writers often refer to Hinduism as 'a way of life' or 'a family of religions' rather than a single religion.*
