Neptune square Lilith (orb 1.1°) 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 Libra in House 9 brings imagination, image, popularity, collective moods, and inspiration into House 9 (vision, belief, study, and wider horizons), with Libra style (relationship, balance, negotiation, and sense of form); Lilith in Capricorn in House 1 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 1 (presence, body, and the way experience is entered), with Capricorn style (structure, ambition, responsibility, and long construction).
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 1.3°) touches an angle; this aspect is easier to notice through first impression, body language, reflexes, and entry style. House 9 (vision, belief, study, and wider horizons) is in friction with House 1 (presence, body, and the way experience is entered); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
