When the ruler of the ninth house is in the eighth house, this means that traveling overseas can be a dangerous or life-changing experience for you.
If this placement is afflicted, long-distance travels can even bring you close to death, or, in the worst case, cause your death. If this placement is not afflicted, traveling long-distance can transform you because of experiencing intense events whilst away from your home country.
This astrological configuration means that you may be good at uncovering the secrets of other countries and cultures (especially distant ones), and you may be interested in researching the customs or religion of some distant country.
Another meaning of this placement is being good at scientific or spiritual research, and being able to write books which are based on a lot of research. This placement also means that if you travel, especially long-distance, you may grow more suspicious and mistrustful because of your experiences there or because of the change in the atmosphere.
Traveling long-distance can make you get in touch with something taboo, and you may end up visiting places which make you feel uncomfortable, or being with people who are dark, secretive characters, or those having obsessions.
This placement means that you should be careful of involving yourself with legal matters, as they can land you in murky waters. Also, involving yourself in legal matters, such as taking someone to court, may cause you to get in debt. Another activity which can cause you too much expenditure is overseas travel.
You may also have an insatiable desire to learn, which can cause you to spend too much money. This can manifest, for example, as a habit of always buying books or spiritual courses.
The ruler of the ninth house in the eighth house shows that you are a natural teacher of that which is secret or occult, and you may also be good at explaining to people how to do research or investigative work.
You may experience anxiety because of your scientific or spiritual philosophies or activities, such as being slandered or getting into dangerous situations because of your religious beliefs.
Possible occupations include that of an archeologist, mystic, spiritual teacher, occult book author or occult publisher, an explorer of overseas cultural heritage or spiritual secrets, near-death phenomena writer or researcher, lecturer on taboo or mystical subjects, and investigator of fraud or similar legal matters.
