Defination of Hindu:'Hin' means to remove and 'du' means darkness. In other words, any one who takes efforts to remove the darkness of spiritual ignorance is a True hindu my frnd..one who follows Hinduism, which is considered to be the oldest major religion still practised in the world today and the name given this religious group after the “Indus” river!! Person who adheres to Hinduism, the religion based upon the Vedas. You cannot elect to become a Hindu. You must be born a Hindu. A Hindu (, Devanagari: हिन्दू) is an adherent of the philosophies and scriptures of Hinduism, a set of religious, philosophical and cultural systems that originated in the Indian subcontinent..
So, is it clear by now what is hindu!! my friend??
