Current faith and practices in Hindu religion is so broad and were much more broader until 16-17th century. They were originated from different groups, places and civilization so it is useless to discuss where the faith in Hinduism originated from because there is no single faith and practice. They are just the collection of different faiths upon Bishnu or Shiva or whoever and practices which were in existence for thousand of years ago and collectively known as Sanatan Dharma. The word Hindu itself did not exist until some 18 th century; it was coined by some British or German scholar. Then present form of Hinduism is much more uniform in terms of faiths and practices though it is still the most diverse as compared to other main religions.
