The book The Universal Symphony of Swami Vivekananda, is a collection of seven lectures by Swami Ranganathananda. The lectures are drawn from the larger work, Eternal Values for a Changing Society. Modern scientific and commercial advancements have turned the world into a "global neighborhood," making mutual understanding and cultural harmony essential for human survival. Vivekananda is presented as the embodiment of this harmony. The note cites Romain Rolland, who described Vivekananda’s genius as a synthesis of all spiritual paths, including the four Yogas, science, art, and practical action.The book aims to help readers grasp Vivekananda’s "saving message" for both India and the world in a modern, deeper context.
