You often hear that your health is in your hands. Well, it literally is. Mudras are hand and finger gestures that we can adopt during meditation or pranayama (breathing exercises). They are considered to be ritual gestures, and you can often see them depicted in ancient scripts and Hindu and Buddhist images. However, mudras can also involve the whole body.
According to the yogic tradition, mudras direct the flow of energy to the body and stimulate different areas of the brain. They help to maintain health and can improve various ailments. In the esoteric context, each finger corresponds to one natural element, namely air, water, earth, fire and ether (space).
