Discover the transformative wisdom of Swami Vivekananda (1863–1902), the Indian Hindu monk, philosopher, and spiritual leader who introduced the ancient teachings of Vedanta and Yoga to the Western world — most famously through his electrifying address at the Parliament of the World's Religions in Chicago in 1893. A disciple of the mystic Sri Ramakrishna, Vivekananda taught that all religions are paths to the same divine truth, and that the greatest service to God is service to humanity. His essential works include Raja Yoga, Jnana Yoga, Karma Yoga, and Bhakti Yoga — practical, accessible guides to the four paths of spiritual realisation that remain as relevant and inspiring today as ever.
