Mars in the 12th house

The 12th house covers solitude, retreat and what stays out of sight. Mars here acts quietly. Effort goes into work nobody watches, and these people often fight harder for others than for themselves. Hospitals, institutions and behind-the-scenes roles suit the placement. Anger is the hard part: it is uncomfortable to express, so it accumulates and comes out sideways or turns inward. Energy tends to run in cycles that are difficult to explain to anyone else.
