The Sun-Mars sextile gives a working channel between intention and action. It is not as free a flow as the trine, where energy often turns on by itself, but here there is a good opportunity to learn to apply strength precisely. The Sun forms the sense of personal direction; Mars gives courage, speed, and readiness to intervene in reality. In the sextile, they support each other through practice: the more consciously the person acts, the more confident their will becomes.
