Mars (action and initiative) enters Sagittarius on September 13th. This will be the transit that lets the animals out of their cages.
Sag is the sign of open horizons, and Mars gallops freely here. If Mars in Scorpio was the deep-sea exploration, Mars in Sag will be the explosion out of the water, onto the shore, and off into the distance. Sagittarius is only interested in what lies ahead. This is the adventurer and athlete combo; action with limitless potential.
Sagittarius (in your chart) is where you can explore and expand. Transiting Mars will be activating this area, so it will certainly be the time to try something new. If you've been depressed, in a rut or lacking motivation...here's your motivation. Put yourself out there, with a few caveats. Mars in Sag can be impulsive. Freedom is the overwhelming theme, but it can be easy to trample over boundaries. Some boundaries are necessary.
The other side of Sagittarius is ethics, ideals and education. Mars can fire up these issues, triggering a lust for more knowledge and/or the fanatical pursuit of a cause. Sagittarius also represents religion, so this is the Crusader transit. Charging after a distant goal because you believe it's right, no matter what. Obviously, there's positive and negative potential to this scenario. If you're charging ahead, spare a moment to consider what others might believe in. What are you fighting for?
Overall, this is the transit that can ignite your personal crusade. What that is will depend on the house(s) in your chart occupied by Sag.
