Dear Brother, Salaam.
Imagine one hindu farmer who lives in a remote village of India. He believes in his Creator and worship Him alone. He leads a righteous life and strongly believes that he will have to return to his Lord one day and face the judgment of his creator for his actions. He has no idea what is Quran or Gospel or Torah. All he knows about Veda and he seriously believes the following verses of Veda:
CONCEPT OF ONE GOD:
"The Formless Supreme Spirit that pervades the universe can have no material representation, likeness or image." (Yajur Veda 32:3.)
"He is bodiless and pure." [Yajur Veda 40:8]
"The Great Ruler of the Universe, Who is Self-existent, All-pervading, Holy, eternal and Formless, has been eternally instructing His subjects - immortal souls - in all kinds of knowledge for their good through the Veda." [YAJUR VEDA 5O; 8].
"May, O Great God, Wises of the wise, through Thy grace, my mind - which like the hub of a wheel into which all the spokes are inserted, is the repository of the Rig Veda, the Yajur Veda, The Sama Veda and also the Atharva Veda, the mind in which Omniscient, Omnipresent conscious Being - the Witness of all - makes Himself known - be freed from all ignorance and be endowed with the love of knowledge." [YAJUR VEDA 34: 5]
"By One Supreme Ruler is this universe pervaded, even every world in the whole circle of nature, He is the true God. Know Him, O man! and covet not unjustly the wealth of any creature existing. Renounce all that is unjust and enjoy pure delight - true spiritual happiness - by the practice of justice and righteousness which is another name for true religion.[YAJUR VEDA 40:1]
"I, O men, lived before the whole universe came into being, I am Lord of all, I am the eternal cause of the whole creation. I am the source and giver of all wealth. Let all men look up to me alone as children do to their parents. I have appointed different foods and drinks for all creatures to give them sustenance so that they may live in happiness." [RIG VEDA 10: 48, 5].
