The alchemists term this the rubedo, in which the marriage of the red man and the white woman, sol and luna, is consummated… The ruler of the rubedo is the mighty lion, which subjugates everything. The rubedo calls to action — decisive, willful action, focus and discipline.
Bosnak defines rubedo as the stage of coniunctio between solar and lunar opposites, characterized by intense heat, the dominance of the lion archetype, and the demand for heroic, focused action.
