Mars is related to energy, pure and simple, and is associated with courage, daring, drive, ambition, anger, and libido. Mars is fast-moving and can be reckless, so it needs a constructive outlet to express itself. If Mars cannot find a way to express itself positively, it may become destructive (fights, aggression, accidents).
Aries is a cardinal fire sign ruled by Mars. When Mars is in Aries, it is said to be domiciled or at home and comfortable in this position. Aries is a passionate (fire) sign and eager to initiate (cardinal) what needs to be done and has the energy (Mars) to do so. What Aries may lack is the discipline to finish what it started (cardinal).
The astrological natal house that Mars is transiting (moving through) in your natal chart will show you what areas of your life are likely to experience an increase in energy, drive, courage, and determination associated with Mars. It will also show where you may be more aggressive and run into conflict with others.
