Vedic astrology uses the precise sidereal zodiac. Sideral means “of the stars”, so it keeps track of the locations of all the planets in the context of the constellations. So when your Vedic chart shows that your Sun is in Leo, it was actually in the Leo constellation when you were born. We understand that Vedic astrology adjusts signs for precession, while Western astrology maintains all signs at fixed times of the year, no matter what.
But this doesn't mean that Western astrology is “not real” or that Vedic astrology is “more accurate”. Because remember, astrology in its origins is not about signs, but about the position of the planets in the sky. Neither the tropical nor the sidereal zodiac are astronomically accurate. The constellations do not form a perfect 360º circle in the sky and astrology explains most, but not all, of the constellations that are closest to the ecliptic (despite reports, there is no thirteenth sign called Ophiuchus).
Annual predictions based on Vedic astrology are more accurate and reliable than those based on Western astrology. All of these sign-based predictions are generic. In Western astrology, the annual prediction is made using the sun sign, so all people born in the same month fall into the same sun sign. They would be inheriting a certain set of characteristics.
However, when we make the annual prediction using Moon signs, two people, although born in the same month but at different times, may have different birth stars. This is why predictions based on Vedic astrology are more accurate. For example, let's say that, according to Western astrology, your sun sign is in Capricorn. In the Vedic system, it could be in Sagittarius.
It's possible that your rising sign and the other planets are also in unknown signs. However, this does not mean that Vedic astrology is inaccurate. Just calculate a horoscope differently. The interpretations are often more precise than in Western astrology.
Western astrology uses a different system, which is much more like an open system in which not much importance is given to traditional methods for preparing the birth chart. Vedic astrology seems to be straighter compared to Western astrology because it is based on more precise astronomical principles. Another reason why the Vedic system is better than the Western system is that it uses the Dasa predictive system. If you are familiar with Western astrology, upon careful examination, the Vedic chart will appear to have planets aligned with the wrong constellations (signs).
In Western astrology, on the other hand, there is no such precise way to calculate the best time to start a new company. Heads of government consult astrologers for guidance, and parents of newborn babies book sessions to learn about their children's life trajectory. Western astrology is mainly concerned with the horoscope, where the sky is divided into 27 constellations, which form the basis of all astrological calculations there along with the Sun. All of these differences make it quite clear that both forms of astrology have their own importance.
Because of this phenomenon, the theoretical Aries of the Western zodiac moves further and further away from the Aries used by Vedic astrologers at a rate of approximately 1 degree every 72 years. Therefore, the Vedic system is more precise because it has remained intact for years, and the basis of the Vedic system is the knowledge used in modern astronomy with respect to any astronomical phenomenon that occurs within the system. Vedic astrology classifies houses in many ways that the Western astrologer does not yet know, such as the four angular houses (first, fourth, seventh, tenth) as kendras and they are the place of power. Horoscope matching is one of the most valuable aspects of Indian Vedic astrology that has been used since ancient times to find out the compatibility of the future bride and groom before marriage.
Western astrologers who study it often convert to Vedic astrology because of its greater reach, depth, and accuracy in predicting the future. The best thing about Vedic astrology is that the planets here are directly related to energizing factors such as yoga, Ayurveda and many other important spiritual assets in India. .
