The Throat has to do with communication, expression, and manifestation through action.
Defined Throat
Communicates in a consistent way with its own voice and may also express and take action in a reliable way. A fixed way of communicating and acting can allow truth to be expressed consistently through the voice. In an unhealthy state, one can over-communicate in a way that is overwhelming to others and leads to resistance, or talks and acts without tracking the impact on others and whether or not they are available to listen.
Undefined Throat
Able to communicate in many different ways or voices and can be quite variable in how much it wants to talk. Able to be wise about who communicates well and whose voice is worth listening to. Can cause asynchronous development in children. In an unhealthy state, talks too much out of feeling pressured to speak when one does not actually have anything to say, and does not respect being silent; can become overly focused on attracting attention and concerned about being visible and making a contribution. Can be highly attention-seeking, especially in personal interactions.
