The Throat Center is about communication. The Throat is the point towards which all the energy in the body is moving to find expression. It is through this center that manifestation, metamorphosis, and transformation take place. The defined Throat speaks in a fixed way, with a consistent expression from whatever energy center it is connected to.
The undefined Throat has no consistent voice, which can cause a nervousness and a pressure to speak. The open Throat can want to attract attention by expressing something or by saying that it will do something (manifest) in order to relieve the pressure. The open Throat can speak in many voices with different ways of expressing, as long as it is not trying to force it. The open center wisdom is to learn that there is nothing that needs to be done or said; silence is okay. The open Throat question is: “Am I trying to attract attention?”
