Uranus square Lilith (orb 1.2°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Uranus in Aries in House 10 brings disruption, independence, and change into House 10 (vocation, status, responsibility, and public image), with Aries style (initiative, speed, confrontation, and direct action); Lilith in Capricorn in House 7 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 7 (relationship, confrontation, and the mirror of others), with Capricorn style (structure, ambition, responsibility, and long construction).
Concrete friction: this aspect puts Uranus (disruption, independence, and change) and Lilith (pure ideal, absolute demand, fascination, and refusal of compromise) into repeated friction: one can interrupt, inhibit, or provoke the other in concrete situations. Visible angle: Lilith near the Descendant (orb 2.2°) touches an angle; this aspect is easier to notice through direct relationships, partners, opponents, and the way others are met. House 10 (vocation, status, responsibility, and public image) 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.
