The Processor
If the Sun is the CEO, Mercury is the Communications Director. It handles the data. It governs your intellect, your speech patterns, and your sense of humor. It is the planet of "connections"—connecting ideas, connecting people, and connecting places (transportation).
The Two Sides: Mercury rules two signs: Gemini (input) and Virgo (processing). It captures both the curiosity to learn new things and the analytical ability to sort that information into useful systems.
Retrogrades: Mercury goes retrograde 3-4 times a year, more than any other planet. This is why it is so famous for "glitches." It forces us to slow down, review, and rethink our plans.
The Nervous System: Physically, Mercury rules the nerves and the hands. A strong Mercury gives manual dexterity and a quick wit, but can also lead to anxiety or overthinking.
