What does this mean?

How this transit might manifest.

When these two planets combine their energies, it can make a lot of personal power available to you to achieve the things you want to get done. You will probably be feeling strong and confident. This will be a good time to address legal matters or to start a fitness routine. Be careful of becoming reckless or overdoing it, physically or in your relationships. All that energy might make you overconfident, or cause you to overreach some boundaries unwisely. You may find yourself being attracted to, or attracting the attention of, more energetic or aggressive people. This transit will probably also give your sex drive a boost in general. You may become restless with the circumstances in your life. Consider getting out more often, or perhaps taking a vacation. Overall, this is an excellent time for you.

If Mars is the ruler of the First House:

You can have a powerful presence when you put your mind to it -- perhaps to the point of being overwhelming of others if you aren't careful. When you make the effort, you can probably gain muscle mass quickly. You are straightforward but may come across as a bit pushy (even when you don't mean to be). "Sitting around and waiting for something to happen" is not your preferred approach to life.

If Mars is the ruler of the Second House:

You may not enjoy being coerced into taking action, but once you start moving on something you can get excellent results. Both a sense of self-worth and a feeling of personal independence contribute to your sex drive. You likely have some talent for making physical objects, and might possibly be good at making money that way. As the song says, you "work hard for the money."

If Mars is the ruler of the Third House:

You have a talent for boldly expressing yourself through your speech and/or writing. That can be a good thing unless you give in to the urge to go on the verbal attack: you might win the debate, but at what cost? You may find yourself either in unnecessary conflicts with siblings, or serving as their defender, or both. You have a busy mind, and maybe a little too intellectually restless to stay focused and on target.

If Mars is the ruler of the Fourth House:

You may sometimes find it difficult to express your anger, aggression, or drives straightforwardly and effectively. You may have had a challenging childhood, and one of your parents (or your early environment in general) may have left you feeling somewhat traumatized. You can be highly effective at managing a home or your domestic surroundings. Normally you are pretty good at acting on your instincts.

If Mars is the ruler of the Fifth House:

You are probably a lot of fun to date, even though settling into a more serious long-term relationship may prove difficult. Sports, games, hobbies, and gambling are all things you probably enjoy putting energy into. You might have a certain quality similar to a child playing in the yard -- even if you aren't a child. However, this can be a highly endearing trait. Learn to work on developing precision and focus.

If Mars is the ruler of the Sixth House:

You are likely a very hard worker -- maybe even overworking yourself at times (but the boss probably appreciates that about you). If you yourself are the boss, be careful that you aren't leaning too hard on your employees for effort and results: not everyone can go as hard as you do! There is a possibility that, if you aren't conscientious about maintaining your health, you might develop issues related to circulation or inflammation.

If Mars is the ruler of the Seventh House:

You are naturally driven to achieve results in long-term relationships and/or business partnerships. You are naturally drawn to partners who prove to be a challenge to you. That can be great... or it can be a reason you end up in difficult relationships and tend to stay there longer than you should. Try to remember that debating with someone can be fun and get results -- or can just lead to squabbling. You can also be a great motivator to others.

If Mars is the ruler of the Eighth House:

You will tend to be passionate about sex, the mysterious, and the occult -- until you lose interest and move on to the next subject. There is a possibility that you were or are affected by past sex-related matters. It might take a long time for you to find someone who is the right sexual "fit" for you. Do your best to find healthy and constructive outlets for your temper. Once you focus on a goal, everyone should get out of your way!

If Mars is the ruler of the Ninth House:

Finding answers to Life's Big Questions, whether for you or the world in general, can be highly motivating for you. Your "love style" may be called "playful." You would probably respond well to travel, interacting with different cultures, and/or Higher Education. You may need to learn to settle down when it comes to pushing your philosophy on others: if you have to preach, try not to dictate.

If Mars is the ruler of the Tenth House:

You are driven to do your best possible work when on the job, but if you feel your position doesn't present enough of a challenge, you will probably want to give up and move on to something better for you. Conflict can arise with superiors if they feel you are bucking for their positions. Alternately, you may find your energies are best suited to self-employment. You might have a great deal of leadership potential, or crave to be a leader.

If Mars is the ruler of the Eleventh House:

You probably would be best suited to work that involves organizing, social events, and/or working together with others for A Higher Purpose. Your circle of friends is probably a unique collection of people -- in other words, possibly a bunch of weirdos (but GOOD weirdos!). They might also be a source of unnecessary drama for you at times. In your relationships, you may seem to your partner like you are too "in your head" too often.

If Mars is the ruler of the Twelfth House:

You might have difficulty finding the right target for your ambition and/or anger. This may result in you questioning your ability to succeed, and thus feed into a self-fulfilling prophesy of failure. Once you've overcome any tendencies that way, however, you have amazing potential for putting your drives to excellent work, done in a sensitive and caring manner. Try not to deny yourself the things that you need to be comfortable.
