Mars square Lilith (orb 0.9°) creates concrete friction between the two planets. The orb is extremely tight; this aspect is one of the chart's strongest signals.
Here, Mars in Gemini in House 12 brings action, courage, competition, and effort into House 12 (retreat, contemplation, long time, and possible confinement), with Gemini style (curiosity, language, movement, and mental adaptation); Lilith in Pisces in House 11 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Pisces style (imagination, faith, compassion, dream, and permeability).
Concrete friction: this aspect creates tension between anger, desire, action, impossible ideal, and refusal to yield. Visible angle: Mars near the Rising sign (orb 0.8°) touches an angle; this aspect is easier to notice through first impression, body language, reflexes, and entry style. House 12 (retreat, contemplation, long time, and possible confinement) 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.
