Hindus themselves use various terms such as sanatana-dharma (loosely translated as “eternal religion”) to describe their faith; the word 
“Hindu” is originally a geographic designation (those who live east of the Indus River) and is not found in any Hindu scriptures.
Hinduism has no single founder. While Hinduism may be a collection of faiths, one basic tenet of Hinduism is a belief in the difference between spirit (eternal) and matter (temporary).
With 400,000 followers, Hinduism is the fourth largest religion in the UK.
