Jyotish is commonly referred as Vedic Astrology. It is a science of light, both the light of celestial bodies and the internal light of the soul, which unfolds the knowledge of how the planets and stars influence an individual human life and general mundane events.
Jyotish uses accurate astronomical data and mathematical calculations to determine the positions of the planets in relation to the Earth at the time of birth. Jyotish is about understanding how to best perform in time. It is a behavior analysis and forecasting system, based on astronomical calculations, that assists in anticipating the benefits and challenges that lie ahead.
How does it differ from Western Astrology?
Western astrology, or Tropical astrology, emphasizes the relationship of the Sun to the Earth and establishes the beginning of the zodiac as corresponding to the start of the Vernal Equinox.
The Vedic astrology is based on the Sidereal Zodiac and the planets’ movements are tracked against fixed observable stars in the sky.
In the year 2013, the difference between the two systems is considered to be between 22 and 24 degrees and indicates the difference between the point of the Vernal Equinox and the first point of the constellation Aries, the difference between how each zodiac determines the starting point..
