"The general description of Lung is that it is a subtle flow of energy and out of the five elements (air, fire, water, earth and space) it is most closely connected with air. However it is not simply the air which we breathe or the wind in our bodies, it goes much deeper than that. Lung is like a horse and the mind is the rider, if there is something wrong with the horse the rider will not be able to ride properly. Its description is that it is rough, light, cool, thin, hard, movable."
