In Taurus, instead of having his nose in books (which is one of his favorite things), Mercury is more inclined to channel and receive messages from the divine through touch, sight, smell, or otherwise through the senses. He has to slow down in order to do this, which goes against his grain….at first. Once Mercury gets to the 3rd decan of Taurus, he’s got this more earthy thing down.
A Mars return occurs when the planet moves through the entire zodiac and returns to the degree it was when you were born. This takes approximately 2 years, so we all have a Mars return quite often in the span of our lifetime. In astrology, Mars represents our assertion, drive, energy, masculine aspects, he’s the gas in our tank. Often he’s put in the box of representing our anger and sexuality. He’s those things too, but as in all things in astrology, he’s much more.
