Expansion is a good keyword for the ninth house. This is where you expand your mind, your ideas and your physical horizons, whether through education or travel. It’s the house of philosophy, with planets here reflecting your worldview, your morality and your religious beliefs. Since the focus is on expansion, however, this house also reflects the way your ideas evolve and change as you learn and grow. Nothing stays the same forever and the ninth house will reveal how your knowledge accumulates and develops and how you handle challenges to your beliefs and opinions.
Higher education is a ninth house issue and so are the law and legal matters. Your attitude towards justice and fairness is shaped by planets in and transits to the ninth house. If you have experienced injustice on a personal level, the ninth house will also shed light on how that experience has shaped you, for better and worse, into the person you are today.
There’s a certain restlessness to the ninth house, because this is where your inner adventurer lives. Itchy feet and a desire to explore have their roots in this house, and the way in which travels broadens the mind is a direct link to this house’s intellectual roots.
The sign on the cusp of the ninth house reveal to what extent you seek change and adventure, or conversely, to what extent you cling to the status quo. It also shows how you react to inevitable change and how easy it is for you to adapt to new ways of life.
