The twelfth house is a fascinating part of the natal horoscope. It contains a very special duality and more power over our lives than most students of astrology realize. It is through the conditions of the twelfth house that the personality remains in bondage to the past.. It is the house of unredeemed karma, energetic situations which create patterns of activities which do not further the advancement of life. It is these patterns and blocks which manifest as our “hidden enemies�? Yet both for the personality and the Soul, the twelfth house is rich in resources, if we only know how to unlock them. The “key�?to this part of the horoscope, like everything else in life, is consciousness (love). Once the door to the twlefth house is opened by the Soul, the individual is aware of the karma of past lives as well as the path of service required to be both self-forgiving as well as self-actualizing.
