Health is the motto of yoga. Many people still think that yoga is religion: others believe it to be a kind of magic. In reality, yoga is a system of physical, mental, and spiritual development. Yoga does not mean just twisting and bending the body. It is a comprehensive mode of culturing the body. It also secures a powerful tool in manifesting the hidden personality of man. Yoga may be the cheapest and most scientific method of ensuring the soundness of the body and mind. Yogic practices are the ideal complement to other forms of physical exercise such as running, cycling, and swimming. Yogic postures systematically work on all the major muscle groups, including the back, neck, shoulders, deep abdomen, hip and ankles, feet, wrists, and hands. By their very nature, yogic practices affect all muscle groups and organs as they simultaneously impart strength, increase flexibility, and bring nourishment to internal organs.
