Sidereal Astrology: Basis for Indian Vedic Astrology

Our Sages or Rishis of the Vedic period (Narada, Vasistha, Saunaka, Jaimini and others) were able to perceive the mysterious star and planetary movements along the zodiacal system through their deep meditation (thapas). They conceived the basic rules of the "nirayana" or sidereal zodiacal system which formed the basis for Indian Vedic Astrology.

Nine Planets

According to Vedic Astrology there are only nine Planets or Grahas which have innumerable influence on human life. Of the nine planets only seven planets are known heavenly bodies: Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn. The remaining two, namely Dragon Head or Rahu and Dragon Tail or Ketu, are known as shadowy planets. Why it is called as shadowy planets? The two planetary positions are calculated mathematically.

Twelve Zodiac Signs

The Vedic Astrology system also conceived the zodiacal system (Circle of animals). It is an elliptical belt along the solar path. This zodiacal belt is extended for about eight degrees on either side of this solar path. Along this zodiacal belt the sun, moon and other planetary motions takes place. Vedic Astrology divides this zodiacal belt comprising 360 degrees into 12 equal parts. Each part of 30 degrees was called as sign or Rasi. This is considered as the fundamental division of Vedic Astrology. The Western terminology of the 12 zodiac signs or rasis and their Sanskrit names are : 1.Aries: Mesha "Ram, goat." ; 2.Taurus: Vrishabha "Strength," or "a bull." ; 3.Gemini: Mithuna; 4.Cancer: Kataka "Crab." ; 5.Leo: Simha "Lion;" ; 6.Virgo: Kanya "Maiden;" ; 7.Libra: Thula (Balance); 8.Scorpio: Vrishchika "Scorpion." ; 9.Sagittarius: Dhanus "Bow;" ; 10.Capricorn: Makara ; 11.Aquarius: Kumbha "Water vessel;" ; 12.Pisces: Meena "Fish;"

27 Star-clusters or Constellations

The Vedic Astrology also set relation between 12 zodiacal signs or rasis and 27 star-clusters and constellations. These unique 27 star-clusters or constellations spread within the elliptic zodiac orbit (solar orbit). Vedic Astrology divides 27 equal divisions of the zodiac orbit (comprising 360 degrees) and each star-cluster and constellation will occupy 1/27 parts or 13 degree 20' of the zodiac orbit. As a result astrology system brings 27 star-clusters or constellations under 12 zodiac signs and unifies both the divisions together.

The twenty-seven nakshatras are: Asvin, Bharani, Krittika, Rohini, Mrigasira, Ardra, Punarvasu, Pushya, Aslesha, Magha, Purvaphalguni, Uttaraphalguni, Hasta, Chaitra, Svati, Visakha, Anuradha, Jyeshtha, Mula, Purvashadha, Uttarashadha, Sravana, Dhanishtha, Satabhishaj, Purvaprostapada, Uttaraprostapada and Revati.

Planetray Transitions in Zodiac Signs / Stellar Constellations

According to Vedic Astrology the nine planets are related to the 12 zodiac signs or rasis and 27 stellar-clusters or constellations. Planetary transitions and its influence on individuals will be calculated according to the birth star (ruling constellation at the time of his birth). Each individual will be related with the respective stellar cluster and zodiac sign at the time of his / her birth. When there are planetary transitions occurring across each specific stellar constellation / zodiac sign, there will be significant influence planets on all the natives.
