This is a powerful lecture delivered by Swami Vivekananda in San Francisco in 1900. This Audiobook published by Advaita Ashrama, a publication house of Ramakrishna Math, Belur Math, India, is one of the best books delineating, in brief, the fundamentals of Vedanta in a lucid, authoritative and candid tone.
Swami Vivekananda was the foremost to introduce Indian philosophies 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 revival of Hinduism in India, and contributed to the concept of nationalism in colonial India. Vivekananda founded the Ramakrishna Math and the Ramakrishna Mission.
