Moon square Lilith (orb 1.3°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Moon in Virgo in House 7 brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm into House 7 (relationship, confrontation, and the mirror of others), with Virgo style (precision, method, usefulness, and attention to detail); Lilith in Sagittarius in House 9 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 9 (vision, belief, study, and wider horizons), with Sagittarius style (expansion, travel, belief, and the search for meaning).
Concrete friction: this aspect creates tension between attachment, childhood imprint, mother image, personal dream, and a non-negotiable ideal. Visible angle: Moon near the Descendant (orb 0.7°) touches an angle; this aspect is easier to notice through direct relationships, partners, opponents, and the way others are met. House 7 (relationship, confrontation, and the mirror of others) is in friction with House 9 (vision, belief, study, and wider horizons); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
