The people of the Indian subcontinent are mostly referred to as the Hindus. Any person, who is born with the religious, philosophical and cultural system of Hinduism, is known as a Hindu. Unlike most other religions, only a born Hindu is a Hindu in the true sense, but it is a religion to which one cannot be converted. The etymological origin of the Hindus has too many theories. In the 2nd century BC, the Chinese people used the term "Hein-tu" to refer to the people of the North India. On the other hand, the Sanskrit term Sindhu has cognate to the use of Indus right from the era of the Indus Valley civilization. The Old Persian name of the Indus River was also known as the Hindus, with a stress on the ‘u’. Therefore, it can be well defined that the term might have originated from the Indus Valley civilization from which the people of the Indian subcontinent have expended. However, if you are looking for a deeper insight into the origin of the Hindus and where they come from, the religious aspect of Hinduism has to be considered. When it is compared to the other religious beliefs, and then the question is espoused as to who a Hindu is, then the real answer would be complicated. Just as a Christian is a person, who follows the scriptures of Bible and the teachings of Jesus Christ and as the Muslims are people, who follow the teachings of Hazrat Mohammed, Hindus are those, who follow the teachings and guidelines that are mentioned in the scriptures of Vedas. The religious texts of Vedas that were written, or rather created in the 1500 BCE, are the sacred and religious texts or scriptures for the Hindus. Hence, a Hindu is a person, who follows these teachings from the religious texts of the Vedas, Vedanta, Upanishad as well as the later religious text of Bhagavad Gita. From the time immemorial, the Hindus have existed and that is the belief that the Hindus have always believed and considered themselves to be. According to Hinduism, Hindus have Brahma as everything and everything in the world, the entire mankind is divine. The Hindus have atman within their bodies and it is believed to be one with the supreme power or Brahman. Hence, a Hindu is considered to be a manifestation of the God in the human self. However, the Hindus have an entirely different feature that not any of the other religions have consisted and that is the inability of the people from other religions to be transformed into Hinduism. Only a born Hindu is considered to be a Hindu in the true sense. And the self of the Hindu will always continue to be reincarnated on this earth until he or she gets Moksha or freedom of the individual self. This aspect of reincarnation is one of the most important one for a Hindu and is considered to be the way that the religion of Hinduism continues on earth.
