Neptune square Lilith (orb 1.7°) 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 Cancer in House 7 brings imagination, image, popularity, collective moods, and inspiration into House 7 (relationship, confrontation, and the mirror of others), with Cancer style (memory, protection, belonging, and family sensitivity); Lilith in Aries in House 4 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 4 (roots, privacy, and inner foundation), with Aries style (initiative, speed, confrontation, and direct action).
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 IC (orb 2.1°) touches an angle; this aspect is easier to notice through private base, family roots, and intimate psychological climate. House 7 (relationship, confrontation, and the mirror of others) is in friction with House 4 (roots, privacy, and inner foundation); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
