Mercury is the smallest of the inner planets of the solar system. Its orbit around the sun is completed in a mere 88 days. Known as the evening star in the early spring, and the morning star in late fall, it was thought for millennia to be two separate stars.
Mercury, as messenger of the Gods gives strong indication of this planet’s meaning in astrology. Mercury rules your intellect and communication. Mercury reminds us that communication is not just speech and hearing. Communication is the assimilation of all the input at that time. Mercury controls how you react to that communication and/or input.
Ruler of rational thought and practical thinking, Mercury’s effect is felt most strongly with how you interact with the world around you and communicate with it. Mercury, by controlling communication, controls the connection to the inner self and the subconscious (which is called “sub” conscious is called such because we are unaware of the thought process, it happens “sub” or below the surface, we cannot easily tap into it). Hence Mercury controls the communication of the sights, sounds, tastes, smells, and physical touch around us and carries those messages to the inner self and the subconscious self. Once received, with rational assimilation of the information, we can interact with the outer world.
Those who are wanting to become more in tune with their physical body would do well to study the Mercury’s effect on your sign.
