Tropical vs. Sidereal
To me, your tropical chart gets at the mask, but doesn't get at the soul. Your sidereal chart resonates with your true self and is my preferred tool.
Western astrology tends to use the tropical system which tracks the position of the ☀️ as seen from Earth against a fixed map. It's based on the position of the stars over 2000 years ago - NOT their positions today!
It claims that seasonal changes, not stars, are at the heart of zodiac sign symbolism. And sure. Seasons impact us. BUT:
... the powerful energy of the stars & planets gets imprinted on your soul at the moment of your birth. THIS creates your Cosmic Blueprint.
Sidereal is based on the stars, adjusting the signs each equinox with the help of corrective measures described in ancient Vedic texts. Over the past 2000 years 🌎's axis has shifted ever-so-slightly (precession of the equinoxes). As a result, where the ☀️ now sits in relation to the ✨ is different from the frozen-in-time Tropical System. The difference is approx. 24° (but can vary up to 39° depending on the date).
