Venus square Mars (orb 0.1°) creates concrete friction between the two planets. The orb is extremely tight; this aspect is one of the chart's strongest signals.
Here, Venus in Scorpio in House 9 brings desire, taste, relationship, and attraction into House 9 (vision, belief, study, and wider horizons), with Scorpio style (intensity, desire, crisis, secrecy, and invisible power); Mars in Leo in House 7 brings action, courage, competition, and effort into House 7 (relationship, confrontation, and the mirror of others), with Leo style (presence, pride, creation, and the wish to be seen).
Concrete friction: this aspect creates tension between attraction, pleasure, empathy, and direct action: the person may alternate between seducing, appreciating the other, attacking, desiring, or turning relationship into a power struggle. Visible angle: Mars near the Descendant (orb 5°) touches an angle; this aspect is easier to notice through direct relationships, partners, opponents, and the way others are met. House 9 (vision, belief, study, and wider horizons) is in friction with House 7 (relationship, confrontation, and the mirror of others); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
