India is home to many religions, but the dominant one is Hinduism. Hinduism, which originated in India, is practiced by over 80 percent of India's population and is the world's oldest religious and philosophical system. Islam is the dominant foreign religion and is practiced by 13 percent of the population.
Hindus believe in the concept of reincarnation, which in Hinduism states that human and animal souls are born again many times in different forms. The escape from the cycle of reincarnation is when Hindus reach Nirvana, which is the reunification of the soul with Brahman, the universal soul that created the universe.
