The Chariot, VII. Victory over ego. Focus. Will in alignment. Moon in Cancer, the crab. Both the sensitive crab and the charioteer wear armor for protection. The chariot itself could be likened to an armored car, protecting what is precious. There is a wisdom to knowing when to go within and when to push forward.
Arcanum VII, rides this discernment. The Charioteer, through sheer determination and the desire to rise above obstacles both internally and externally seeks to overcome the limitations of self. Driving Will in action, the charioteer barrels down the path of self-realization.
This warrior holds no reins, but sits in a meditative posture, aligning their will with that of the All.
