Moon square Lilith (orb 1.6°) 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 11 brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Sagittarius style (expansion, travel, belief, and the search for meaning); Lilith in Virgo in House 8 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 8 (sexuality, shared power, crisis, and invisible bonds), with Virgo style (precision, method, usefulness, and attention to detail).
Concrete friction: this aspect creates tension between attachment, childhood imprint, mother image, personal dream, and a non-negotiable ideal. House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects) is in friction with House 8 (sexuality, shared power, crisis, and invisible bonds); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
