Neptune opposite Lilith (orb 2°) puts the two planets face to face, with visible back-and-forth or tension. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Neptune in Leo in House 6 brings imagination, image, popularity, collective moods, and inspiration into House 6 (daily work, technique, and bodily discipline), with Leo style (presence, pride, creation, and the wish to be seen); Lilith in Aquarius in House 12 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 12 (retreat, contemplation, long time, and possible confinement), with Aquarius style (independence, networks, distance, and collective change).
Concrete conflict: this aspect sets Neptune (imagination, image, popularity, collective moods, and inspiration) across from Lilith (pure ideal, absolute demand, fascination, and refusal of compromise), with a back-and-forth that answers or contradicts itself. Visible angle: Neptune near the Descendant (orb 2.2°) and Lilith near the Rising sign (orb 0.2°) touch angles; this aspect is easier to notice through direct relationships, partners, opponents, and the way others are met; also through first impression, body language, reflexes, and entry style. The house conflict is between House 6 (daily work, technique, and bodily discipline) and House 12 (retreat, contemplation, long time, and possible confinement); pressure in one field tends to reactivate the other.
