Vivekananda (1863-1902) was the foremost disciple of the great mystic Ramakrishna. Well educated and articulate in English, he spoke at the World’s Parliament of Religion in Chicago in 1893, describing Vedanta as a rational, spiritual, and universal tradition. He established Ramakrishna Vedanta Societies in the United States and the more socially-activist Ramakrishna Mission in India before his death at thirty-nine years of age.
