Astrology is a complex science and unfortunately, most of the information out there is aimed at either people who are just browsing for general horoscopes, or astrologers themselves. It can be difficult to find a happy medium when trying to learn about how the heavens affect us.

For this reason, I have compiled a short list of some of the most common astrological terms that you might come across when reading an astrology report of article. Of course, if you have any questions about astrology, or about my astrology readings and reports, please don’t hesitate to contact me. I would be happy to help you on your journey through the cosmos.
