Vedic Astrology originated from ancient India, and was documented by sages in the Vedic scriptures. It is know also as "Jyotish"- the science of light. Basic foundation of Vedic astrology is Brihat Parashara Hora Sashtra by Rishi Parashara, Jaimini Sutras by Rishi Jaimini, Bhrigu sutras of Rishi Bhrigu, Brihat Jataka of the great Varaha Mihira.
Astrology is the science of the effects of planetary movements on our lives. Astrology is based on astronomy, and astrologers need to know the correct positions of the planets at any given time, as well as the correct positions of the zodiacal fixed star signs in relation to any place on earth at any given time. Once the correct positions of the signs and planets are known, astrologers can construct charts representing these positions. Astrologer can study the charts and try to understand our karma for this life. Your karma is determined by a predestined cosmic design. You are a soul incarnating in a body at a very specific time and place. Your Vedic chart will most likely reflect your real life. The Vedic astrologer looks at these planets, signs and house placements in your chart and can "see" your personality, as well as life events and possibilities - both the good and the bad times in your life.
