Asana originated as a Sanskrit word meaning a sitting position used for meditation and yoga practice. Traditional yoga texts describe asana as one of the eight limbs of yoga and define it as a steady, comfortable posture used to sit for meditation. Asanas can be meditative postures that position the body for prolonged sitting, relaxative postures like shavasana that induce relaxation, or cultural postures incorporated into a daily exercise routine to improve physical health. Physically, regular asana practice provides benefits like increased flexibility, strength, balance and decreased stress and symptoms of back pain.
