Black Moon Lilith is a calculated point based on the lunar apogee. In astrology, it represents the deeper mysteries and the shadows around us. It's named for Lilith, whom in Judaic mythology was the first wife of Adam (and not Eve). Lilith refused to bow to Adam (so to speak), and was forced to leave Eden.
Lilith marches to the beat of her own drum, and does not bow to patriarchy. Where the deeper shadow work, female sensuality, or occult lies, Lilith's influence can be found. She rebels against the traditional.
