Moon square Lilith (orb 1.8°) 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 Taurus 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 Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance); Lilith in Aquarius in House 9 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 9 (vision, belief, study, and wider horizons), with Aquarius style (independence, networks, distance, and collective change).
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 9 (vision, belief, study, and wider horizons); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
