Venus square Mars (orb 0.4°) 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 Libra in House 7 brings desire, taste, relationship, and attraction into House 7 (relationship, confrontation, and the mirror of others), with Libra style (relationship, balance, negotiation, and sense of form); Mars in Capricorn in House 11 brings action, courage, competition, and effort into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Capricorn style (structure, ambition, responsibility, and long construction).
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. House 7 (relationship, confrontation, and the mirror of others) is in friction with House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
