The Throat Center
The only centre that turns anything into a thing other people can see.
Defined Throat
You have consistent access to expression. Words and action come out reliably, and you are rarely stuck for how to say something, though what you say still depends on what is connected to it.
Open or undefined Throat
Expression comes and goes with the company. An open Throat feels enormous pressure to speak in order to be noticed, and speaks best when it has been invited rather than when it has forced its way in.
The not-self theme: Talking to get attention, then feeling worse. The classic open Throat move is interrupting to prove you are there.
What an open Throat eventually becomes
An open Throat learns exactly when speech will land, because it has felt so acutely when it does not.
This is the part most people miss. An open centre is not a deficiency to be fixed. It is where you take in and amplify other people, which is uncomfortable for years and then becomes the thing you understand better than anyone with it defined.
The gates of the Throat
11 of the 64 gates sit in this centre. Each is also a Gene Key, read as a Shadow, a Gift and a Siddhi rather than as a mechanic.
Centres, gates and channels come from the same tables the bodygraph is drawn from. Human Design was assembled in 1987; Six Mirrors reads it beside five older systems and shows where they agree.
