Hinduism - Hinduism world third largest religion:-

There are 750 million Hindus in the world, and most of them live in India . Hinduism includes a very wide range of faith and practices. They all have a "family resemblance" to each other. The things most ordinary to Hindus are a belief in a single Divinity or supreme God that is present in everything, faith in other gods who are aspects of that supreme God, belief that the soul repeatedly goes through a series of being born into a body, dying, and regeneration, belief in Karma, a power that determines the value of each life, depending on how well one behaved in a past days.

Hinduism has developed to become the world's third largest religion, after Christianity and Islam. It claims about 762 million followers - 13% of the world's population. It is the leading religion in India , Nepal , and among the Tamils in Sri Lanka .

Hinduism is the name given to a family of religions and cultures that began and still thrive in India .
Like other Eastern religions, it doesn't fit happily into the same box as Western religions like Christianity.

Hindus do not divide religion from other aspects of life. For Hindus in India , Hinduism is an inextricable part of their survival, a whole idea of life that involves communal class, earning a living, family, politics, diet, etc.The word "Hindu" comes from the name of the river Indus , which flows 1800 miles from Tibet through Kashmir and Pakistan to the sea. Originally the name referred to people living in a niche region of the world, despite of their faith.
 

Hindu temples are the center of religious life, but there is not a strong custom of shared congregational respect. Hinduism has not had a major tradition of seeking to change people.
