"All About the Throat Chakra
The Throat Chakra is associated with the color sky blue. This chakra is our will center. The healthfulness of the fifth chakra is in relation to how honestly one expresses himself/herself. Lying violates the body and spirit . We speak our choices with our voices (throats). All choices we make in our lives have consequences on an energetic level. Even choosing not to make a choice such as in repressing our anger (not speaking out) may manifest into laryngitis. We have all experienced that "lump in our throats" when we are at a crossroad of not knowing how to speak the right words in any given situation, perhaps even stuffing our own emotions. A challenge of the throat chakra is to express ourselves in the most truthful manner. Also to receive and assimilate information. Seek only the truth.
