Ancient Indian science dates back to Vedic times and we can find references of Vedic astrology in Atharva-Veda (one of the four ancient Indian sacred texts). Vedic astrology is scientific in nature and utilizes complicated mathematical calculations to get sharp and precise astrological predictions and foresights. Indian Vedic Astrology along with KP (Krishnamurthy) Astrology offer the most powerful predictive system compared to other forms of astrology.

This ancient Indian sciences works on a principle based on 12 Zodiac Signs (Rashis) comprised of 27 + 1 Constellations (Nakshatras), 9 Planets and 12 Houses in a Birth Chart called Kundali. This Kundali is further divided into 16 + 4 divisional charts called Vargas (the latter 4 being attributed to Jaimini) to further unfold the mystery a Kundali.

“No conclusion can be made on any horoscope without considering relevant Vargas.”
— sage Parashara (Brihat Parashara Hora Shastra)

Basically, Kundali is exact picture of sky at time of your birth with placement of planets in the sky. The science applied for predictive analysis of a Kundali is known as Vedic astrology.

Present day Indian astrology is based on the principles of astrological classics written by scholarly sages like Parashara, Jaimini, Varahamihira, Garga and their followers.

When compared to other popular forms of astrology, Vedic Astrology seems upright because it relies on more accurate celestial principles. For example, Western astrology uses fixed zodiac while the Vedic astrology uses movable zodiac to determine the origin point of the zodiac. Western astrology is based on Sun sign, which changes its sign in around one month whilst Vedic astrology, which is based on Moon sign is more accurate as Moon changes its sign in 2-1/4 days.

Above all, Vedic Astrology works on very ancient scientific principles of predictive techniques and remedial measures which are tested for thousands of years and are now appreciated worldwide and getting popular now with innovation of internet and electronic media.
