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.
Defining Hinduism
The term 'Hindu' was derived from the river or river complex of the northwest, the Sindhu. Sindhu is a Sanskrit word used by the inhabitants of the region, the Aryans in the second millennium BCE. Later migrants and invaders, the Persians in the sixth century BCE, the Greeks from the 4th century BCE, and the Muslims from the 8th century CE, used the name of this river in their own languages for the land and its people.
The term 'Hindu' itself probably does not go back before the 15th and 16th centuries when it was used by people to differentiate themselves from followers of other traditions, especially the Muslims (Yavannas), in Kashmir and Bengal. At that time the term may have simply indicated groups united by certain cultural practices such as cremation of the dead and styles of cuisine. The 'ism' was added to 'Hindu' only in the 19th century in the context of British colonialism and missionary activity.
The origins of the term 'hindu' are thus cultural, political and geographical.
