The power of sound is contained within this concentration symbol. It is vibrant within the mind - when that vibrant force moves downward it instigates the movement of the vocal cords and thus creates our voice. Through the controlled use of the voice we can actually calm the mind and bring it to a state of meditation. controled use of the voice in such a fashion is called Mantra Yoga. Yoga teachers are trained in the art of mantra as well as in the postures of hatha yoga and the practices of pranayama in order to become certified.
