The throat chakra corresponds to the energy of inspired creativity. It is also the center for communication, including the speaking of truth; hence, in yogic teaching, it is believed to be the first of the higher, or spiritual, chakras.
If the throat chakra is in balance, then one is expressing their authentic truth openly and honestly. In relationships, one is able to be true to one's self and to express one's beliefs without fear.
If this chakra is out of balance, it is thought to cause problems physically with thyroid disorders, sore throats, fevers and infections. It can also be linked to neck and shoulder problems.
There are certain yoga practices that are believed to help activate and balance the throat chakra. These include chanting and mantras, as well as the plow pose and the fish pose, among others.
