ALMUTEMMars in House 12
Mars represents your energy, your desire and the courage to act. House 12 is the house of what stays hidden: retreat, what goes on behind the scenes, secret fears and what holds you back within. It's a difficult place, but also one of silence and of the inner life.
In the twelfth house — of hidden enemies, of confinement, of grave illness, of institutions, and of sorrows — Mars occupies a cadent house, where his force acts only in part, far from the vigour of the angles. The house of Saturn's joy, the most shadowy of the chart, it is the soil of prison and of secret; the heat of Mars buries itself here in the hidden. It inclines to the enemy who wounds in the dark, to the treachery prepared far from sight, to the ambush and the blow from behind. Determined to confinement, he gives peril of dungeon, of hospital, of exile; to grave illness he adds his iron. It tends to the wrath that turns inward, to the malady that gnaws in silence, to the ruin plotted by a hidden hand. It gives strength to endure in isolation, courage in silent adversity. The force moves here in the dark, where the blow is not seen coming. But whether it strikes or is struck is told by the sign that lodges him.
