The body consists of a network of energy channels (nadis) where energy (prana) circulates. One channel runs along the axis of the body, from the base of the spine to the crown of the head. In the ordinary individual this central channel of subtle energy is said to be mostly inactive. One purpose of Hatha Yoga is to clear this channel of any obstructions. The energy then can flow freely leading to better health and higher states of consciousness. When this channel is activated it sets the six chakras in motion. Chakras are psychoenergetic centers which are aligned along the central channel.
