Nemesis was the goddess of due enactment, a karmic equalizer who ensured that no one had too much good fortune, but paid appropriately for their misdeeds. Known as the restorer of cosmic order, Nemesis was particularly focused on punishing acts of hubris, which is defiant pride or arrogance in one’s place, gifts or fortune. Eventually her concept was refined to include a quality of vengefulness or retribution which is lacking in the original, which was more about rectifying imbalance. In modern usage, the tern “nemesis” has come to represent any opponent, competitor, or adversary, anyone who stands in the way of our goal, or enacts revenge for wrongs committed
Astrologically, Nemesis represents the vagaries of Fate, self-undoing, reversal of fortune, and any person or thing which holds us back, prevents our will, denies goals, or punishes our actions. Additionally, there can be issues with assigning blame, scapegoating, or finding fault.
