So, the East is dominant, right? This is still considered when we speak of rising planets, especially in return charts.
What about the planets below the horizon?
Earlier in the zodiac dominates (well up to the opposition). So a planet in Capricorn on the Descendant dominates a planet in Pisces in the ninth, even though Capricorn is the most westerly sign.
Ronia said:Being practical here, I don't really think my Sun is dominated by nearly every other planet in my chart, as this distinction suggests. I guess this is just one consideration of more.
Your Sun dominates any planet in later sign connected by a major aspect up to it's opposition. That is any planet to which it makes a sextile, square or trine to its left.
Yes other factors may effect that butas a general rule that's how they saw it. It's always worth rotating the chart if you're not sure if it's the planet on the left or the planet on the right
