The Vedic Acharya Jyotish Prediction is based on:
1) The Signs of the Zodiac or 12 Rashis are constellations used in astrological predictions. Each Planet or Graha moves through the Signs of the Zodiac at a different speed. For example, the Sun passes through each Rashi in one month, and the entire circle of 12 Rashis in the course of one year. This is why the Signs of the Zodiac are referred to as Solar Constellations.
3) Lunar Constellations: The 27 NakshatrasSignify a specific quality of Natural Law that influences your life, and are represented as 27 equal segments of a circle. Like the Planets or 9 Grahas, each Nakshatra represents a specific quality that influences your life. The word “Nakshatra” can be translated as “that which does not decay.” Nakshatras are understood to permeate the entire universe.
