Sivananda Yoga is a spiritual yoga system founded by Vishnudevananda; it includes the use of asanas but is not limited to them as in systems of yoga as exercise. He named this system, as well as the international Sivananda Yoga Vedanta Centres organization responsible for propagating its teachings, after his guru, Sivananda with the mission 'to spread the teachings of yoga and the message of world peace' which has since been refined to 'practice and teach the ancient yogic knowledge for health, peace, unity in diversity and self-realization.'
