Signs, Constellations and the Stars
Constellations are very important in Astrology - not only the 12 to 13 zodiacal Signs but also the surrounding constellations that are either south or north of the ecliptic. They give a finer touch or information about the "how" of expression.
The individual Stars are talking as well - if in a horoscope a celestial Body is directly conjunct then that wants to tell us something and we have to look more closely. The same is about other strong alignments and aspects.
As I do the Star-watching ritual so often, I use a zodiac that is based on the actual placements of the celestial Bodies as viewed from Earth. Because of this, I start the subpages and descriptions with Pisces as it's currently the sign, where the spring Equinox occurs.
