Maharshi Dayanand Saraswati
Jivan Charitra !!
Saraswati, Dayananda, 1824-83, Indian religious reformer, founder of the Arya Samaj movement. He was a Brahman from Gujarat who became the major spokesman for the 19th-century Hindu revival that placed exclusive authority in the Vedas.
He condemned idol worship, untouchability, child marriage, and the low station of women, which he said were not sanctioned by the Vedas. In 1875 he founded the Arya Samaj [society of nobles] in Bombay to spread the doctrines of the newly reinterpreted Vedas. Although he was little concerned with politics, his message reawakened the Hindu traditionalists and reinforced the division between Muslim and Hindu in India.
Vedas are the fundamental base of vedic culture. These are the source of knowledge, Science and Religions etc. Vedas are the eternal knowledge provided by God which consist of all the preaching related to duties and karmas.
Vedic culture is the universally adaptable culture. All the science and knowledge which we see in the world is extracted from the Vedas only. This is the reason that all the Rishies-Maharshies and Acharyas have sung the hymns of the significance of Vedas. Maharshi Manu declares as "VEDO AKHILO DHARMMULAM" Manu.
