The first 5 Gates that cover 0° to about 28° Gemini are all Throat Center Gates. The Throat Center is our center of manifestation and expression. All other centers try to output their energy out the Throat. Each Gate in the Throat act as a "voice". Each voice expresses something specific. It's ironic that Gemini has all these Throat Gates, especially considering how a big trait of Gemini is talking/expressing itself.
