In Vedic astrology, your Surya Rashi (Sun Sign) represents the exact sidereal constellation occupied by the Sun when you were born. In ancient Sanskrit texts, the Sun is called the Atmakaraka or natural signifier of the soul (Atman). It governs your inner willpower, vital energy, father figures, relationship with authority, and personal integrity.
While Western astrology uses the tropical zodiac based on the seasons, Vedic astrology uses the sidereal zodiac based on fixed constellations. Because the Earth wobbles slightly on its axis over long periods (a movement known as precession), the sidereal zodiac shifts backward by approximately 24 degrees compared to tropical dates. This means that if your Western birthday falls in early Taurus, your Vedic Surya Rashi is often Aries.
The Sun establishes your overarching sense of purpose. It shows what kind of work makes you feel proud and where you seek respect in society.
