Neptune square Lilith (orb 1.6°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Neptune in Capricorn in House 3 brings imagination, image, popularity, collective moods, and inspiration into House 3 (speech, learning, and the close environment), with Capricorn style (structure, ambition, responsibility, and long construction); Lilith in Libra in House 12 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 12 (retreat, contemplation, long time, and possible confinement), with Libra style (relationship, balance, negotiation, and sense of form).
Concrete friction: this aspect puts Neptune (imagination, image, popularity, collective moods, and inspiration) 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 Rising sign (orb 2.2°) touches an angle; this aspect is easier to notice through first impression, body language, reflexes, and entry style. House 3 (speech, learning, and the close environment) is in friction with House 12 (retreat, contemplation, long time, and possible confinement); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
