Vedic astrology is based on ancient Indian science that describes the planetary motions and positions with the respect to time and the ultimate effect on humans. It is considered one of the basic forms of astrology because, when it was first discovered, it was solely based on the movement of the planets with respect to the solar system and stars. Later in years, zodiac signs were added to correspond with new popular beliefs. A Vedic astrological is performed by an expert, and is always unique to every person.
