In India, 80% of the population believe in Hinduism, the dominant religion of the subcontinent. It is the third largest world religion after Christianity and Islam with 900 million followers worldwide. It is also the oldest religion in the world. The religious moral is based on Karma (law of revenge of all deeds and the transmigration of souls) and Dharma (moral world order) and social norms. There is no single founder or scripture and no commonly agreed set of teachings. The Hindus believe in a cycle of life, that means in birth, death and reincarnation (rebirth). The more good you do the more closer you get to attain nirvana.
