The 12 Houses of astrology are symbolic of the all the departments that make up human life. The planets and zodiac signs will manifest themselves most strongly in the sphere of life represented by the House in which they fall on your chart.

The houses are the fields of experience, not the experience themselves.

in seventh house, Ceres’s nurturing function is expressed within realm of close interpersonal relationships. In romantic partnerships, the non-negotiable need for a solid emotional foundation is strongest with this placement.
The relationship with your parent(s) sets up your psychological foundation for future relational dynamics. For this reason, it is worthwhile to examine your experiences with regard to how you relate to other people. This includes defense mechanisms, projection and communication patterns.

On the other hand, Ceres can represent our desire to give love and nurturing to others. In this case, it may be that you serve as a loving parental figure to your companion’s inner child.
The realm of relationships can provide a safe container from which to spring forth into the world to accomplish goals. In this case, your ability to feel foundationally strong is directly linked to the quality of your closest relationships.
