Moon square Lilith (orb 1.4°) 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 Sagittarius 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 Sagittarius style (expansion, travel, belief, and the search for meaning); Lilith in Pisces in House 11 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Pisces style (imagination, faith, compassion, dream, and permeability).
Concrete friction: this aspect creates tension between attachment, childhood imprint, mother image, personal dream, and a non-negotiable ideal. House 7 (relationship, confrontation, and the mirror of others) is in friction with House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
