Your rising sign reveals how you interact with the world, from your appearance, to your attitude, to the first impressions you make on others, note the twins. For example, they add, the Capricorn Sun with a Leo rising is likely to display Leo-like traits that you wouldn’t expect from typical Capricorn energy, or even look like a Leo.
Your rising sign also determines your place first house The identity falls into your blueprint (your ascent is always your first house), paving the way for the rest of the houses in your blueprint.
As the twins explain, “The zodiac wheel begins with the first house, which represents the place where the sun was rising above the eastern horizon at the moment of your birth, governing self, identity and your first impression. The houses then move counterclockwise around the zodiac wheel and extend to broader themes related to family life. / Household, community, and beyond.”
Without knowing your ascendant sign, then, the rest of your birth chart will ultimately remain a mystery, because the houses in astrology are just as important as the planets and signs when it comes to fully understanding the chart’s positions and aspects.
