At its core, Sivananda Yoga is geared toward helping students answer the age-old question, "Who am I?" This yoga practice is based on the philosophy of Swami Sivananda of Rishikesh, India, who taught disciples to "serve, love, give, purify, meditate, realize." In order to achieve this goal, Sivananda advocated a path that would recognize and synthesize each level of the human experience, including the intellect, heart, body, and mind.
In 1957, his disciple Swami Vishnu-devananda introduced these teachings to an American audience. A few years later, Vishnu-devananda founded the International Sivananda Yoga Vedanta Centers, summarizing Sivananda's system into five main principles: proper exercise (asanas); proper breathing (pranayama); proper relaxation (Savasana, or Corpse Pose); proper diet (vegetarian); and positive thinking (Vedanta) and meditation (dhyana).
There are more than 80 Sivananda-based centers worldwide, as well as ashrams and teacher-training programs, all of which follow a hatha yoga practice emphasizing 12 basic postures to increase strength and flexibility of the spine. Chanting, pranayama, and meditation are also included, helping students to release stress and blocked energy.
