A "Swami" is a title used in Hinduism to refer to a spiritual teacher or master. The term is derived from the Sanskrit word "swāmin," meaning "lord" or "master." Swamis often lead a life of renunciation and are dedicated to spiritual practices, guiding others on their spiritual journeys. They may be associated with specific ashrams or spiritual organizations. Swamis can be found in various traditions within Hinduism, each with its own teachings and philosophies. Some well-known Swamis include Swami Vivekananda, who introduced Hindu philosophy to the West, and Swami Sivananda, known for his teachings on yoga and meditation.
