What is Astrology?
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.
Using his knowledge, the astrologer can study the charts and can make a wide range of conclusions about the moment the chart was cast for. Primarily, astrology is used to understand one’s self, and our karma for this life.
How is it Different from Western Astrology?
Vedic astrology differs from Western or Tropical astrology mainly in that it uses the fixed zodiac as opposed to the moving zodiac. Because of the gradual tilting of the earth in space on its axis, the zodiac, if you calculate it from the sun’s relationship to the earth, appears to be moving at the rate of a little less than 1/60th of a degree per year.
Currently, the relative or movable zodiac is off or out of alignment with the fixed or real star-based zodiac by roughly 23 degrees, which is almost one whole sign of the zodiac.
