Swami Vivekananda was an Indian Hindu monk and the chief disciple of the 19th-century Indian mystic Sri Ramakrishna. He was a key figure in the introduction of the Indian darsanas (teachings, practices) of Vedanta and Yoga to the Western world, and is credited with raising interfaith awareness, bringing Hinduism to the status of a major world religion during the late 19th century. He was a major force in the contemporary Hindu reform movements in India, and contributed to the concept of nationalism in colonial India. He founded the Ramakrishna Math and the Ramakrishna Mission. In India, He is regarded as a patriotic saint, and his birthday is celebrated as National Youth Day.
