Mercury Retrograde is a transit in which the planet Mercury slows to a point that it appears to move backwards.
All planets in the Universe are in motion, all of the time — some moving forward at a normal speed, and some moving slowly, giving them the impression of backwards (or retrograde) movement. Planets moving forward are considered “Direct”. When a planet is retrograde, all of the life themes that it rules slow down as well.
Mercury rules the themes of communication, transportation, messages, short journeys, higher level thinking and all gadgets and devices that run these parts of our lives. So if you ever wondered why your computer crashed, your cell signal went down or your car wouldn’t start, now you know — that’s Mercury having some fun with you.
