Hatha Yoga is the most widely practiced form of yoga. It is the branch of yoga that concentrates on physical health and mental well-being. Hatha yoga uses bodily postures (asanas), breathing techniques (pranayama) and meditation (dyana) with the goal of bringing about a toned, healthy body and a clear, peaceful mind. There are numerous hatha yoga postures, with hundreds of variations, which work to make the spine supple and to promote circulation in all the organs, glands and tissues. Hatha yoga postures also stretch and align the body, promoting balance and flexibility.
