Neptune opposite Lilith (orb 0.5°) puts the two planets face to face, with visible back-and-forth or tension. The orb is extremely tight; this aspect is one of the chart's strongest signals.
Here, Neptune in Sagittarius in House 7 brings imagination, image, popularity, collective moods, and inspiration into House 7 (relationship, confrontation, and the mirror of others), with Sagittarius style (expansion, travel, belief, and the search for meaning); Lilith in Gemini 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 Gemini style (curiosity, language, movement, and mental adaptation).
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 2.4°) and Lilith near the Rising sign (orb 2.8°) 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 7 (relationship, confrontation, and the mirror of others) and House 1 (presence, body, and the way experience is entered); pressure in one field tends to reactivate the other.
