The Ninth House of your horoscope is ruled by Sagittarius and Jupiter. It describes travel and travel in the mind. Real journeys and intellectual, educational, academic or spiritual journeys.
The Eighth House is ruled by Scorpio and Pluto. Robert Hand notes, "Death. Inheritance. Other people's money" in his book, Horoscope Symbols but neglects to mention sex.
The Seventh House is ruled by Libra and Venus. Venus also rules the Second House, which is about jewellery, gold and money, as well as food - all the valuable items of life.
Cancer is a sign very much associated with home. House, apartment, land, garden, home town, homeland. I often find crab shells in the water, which are reminders that Cancer carries her/his 'home' as part of himself or herself.
The Third House, at its core, is about being heard and read. Thus we go into areas like literacy, translation, speech impediments, deafness, public speaking, and of course vision, as one has to read, in order to translate and transmit.
The first house is about appearances. You can be the real you, away from what you wear, and how you use your body language, and how you are profiled. But - image matters.
