The simile is that of a tree: Tradition as the roots, Modern as the branches. What I'll be explaining is one Astrologer's view (mine, of course
) of what Tropical Astrology means to that Astrologer. The views and opinions expressed here are not meant to supersede anyone else's; and constructive engagement is encouraged and welcomed. This is just one proposed branch among the many others of Modern Astrology.
I see what I'm labeling "Native-rulership" as a Vibration that affects our Psyches and produces an effect called a "Sign". 12 primary Vibrations, each producing its own Sign-effect. The Ecliptic is like a clock-face, and the point where the line of Celestial Longitude that intercepts a Planet crosses the Ecliptic, is an Indicator, like a clock-hand. Two other Indicator positions are among the 12 Native-rulers--The Ascendant (where the Sun would be if it were rising, which is the point where the Ecliptic crosses the Western Horizon in any given location at a given time); and the Age-indicator, which moves due to Earth's "wobble" as it rotates, and is synchronized to a Terrestrial Vibration using the Line of Apsides of Earth's elliptical orbit. Synchronization of a currently unknown cause is involved with all the Indicating points.
A "Native-ruler" is the progenitor of a Sign, the Vibration that produces that effect in our Psyches. But, other types of Vibrational-rulership affect each Sign as well, and may even outweigh the influence of the Native-ruler, depending on other factors, such as Houses and Aspects.
