Sun square Lilith (orb 2.9°) creates concrete friction between the two planets. The orb is tight enough to count in the main reading.
Here, Sun in Cancer in House 12 brings identity, ego, father figure, visibility, and direction into House 12 (retreat, contemplation, long time, and possible confinement), with Cancer style (memory, protection, belonging, and family sensitivity); Lilith in Libra in House 4 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 4 (roots, privacy, and inner foundation), with Libra style (relationship, balance, negotiation, and sense of form).
Concrete friction: this aspect puts ego and personal image under pressure from Lilith's absolute ideal and refusal of compromise. Visible angle: Lilith near the IC (orb 0.8°) touches an angle; this aspect is easier to notice through private base, family roots, and intimate psychological climate. House 12 (retreat, contemplation, long time, and possible confinement) is in friction with House 4 (roots, privacy, and inner foundation); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
