The science of Astrology
Horoscope, Numerology, Vastu Shastra or any other science is beyond the rules of planets, signs, constellations and numbers given in any book. Vedic texts suggest that the work of great virtue and perseverance is the only way to become an accurate astrologer, unlike someone who predicts merely with the knowledge of zodiacal configuration, some mathematics and rules studied from the books.
Practical application of the above understanding is subject to one’s own choices, and it is recommended only after taking suggestions from a Subject Matter Expert.
