Whenever Mars is in the sign of the Scales, he's in the sign of his detriment.
What exactly does that mean? It means that Mars is at a disadvantage because he has to abide by Libra's rules, which requires him to be gracious, polished, poised, romantic, considerate, fair, cooperative, beautiful and balanced.
One's first instinct might be to say, "Well, good luck with that!"
After all, Mars is an ego-driven planet that has a well-deserved reputation for being rough around the edges. True, but more than that, Mars is a competitor who never backs down from a challenge, so despite the odds being stacked against him, he always rises to the occasion.
While Mars is in Libra, his ambition is subdued, his aggression is diluted and he sheds his winner take all approach to life. When he tries his hand at fairness and diplomacy, he discovers that he's an excellent mediator. Even more surprising, he has a desire to settle down.
Still, while there is much for Mars to appreciate about life in this balanced sign, he is never entirely comfortable here. Hard as he may try to suppress it, his ego and sense of self remain strong, and he can never really embrace Libra's me before you lifestyle.
When all is said and done, Mars may not be at his best in Libra, but he's always the best he can be.
And sometimes, that just has to be good enough.
