A First Quarter Square between the Libra Moon and Cancer Sun (27 deg) also includes the Sun's opposition to Black Moon Lilith in Capricorn.
Here is a point of tension that asks you to find a balance between extremes. Needs or family issues that are rooted in the past may be challenged by emerging taboos (sexual or otherwise) that confront you with what lies outside the comfort zone. Lilith is the force on the fringes - she is not accepted by polite society, and this also gives her power. Cancer is cozy, familiar and traditional. The mother. BML is the anti-mother: the disruptor that challenges family dynamics or forces you to acknowledge some "unacceptable" needs.
Libra harmonizes. This may be the last thing you want to do, but the First Quarter Square is about taking a step forward and the only way it can be accomplished is to find that point of compromise. You're not giving in or glossing over the issue with a polite smile, you're acknowledging that there are two side to this story; the side that's always been and the newly disruptive force. Both are valid. Is a union between the two possible?
Find that balance and there's your key to progressing through the crisis.
