The ninth house rules our thoughts and ideas, our mental explorations. It is about expanding the inner self and thinking big. It rules curiosity, journeying and the kind of education we get from international travels or living abroad. It is about expanding our horizon and learning to take the long view, developing multiple perspectives (or not). It rules international travel.
The work of the 9th house is about understanding and integrating what we see and feel. It's also our personal quest for the meaning of life. It is the house of philosophy and contemplative activities. It also rules moral and ethics.
At last, this house rules reading, publishing and the media.
