In Vedic Astrology, the Sanskrit term “Dasha” means the planetary period. The planetary period provides information to astrologers when the good or bad effects are produced as per Planets placement in Zodiac sign, House, Yoga formed and Aspects. This Dasha system is very unique to Vedic Astrology and nowhere it has found. As per Sage Parashara, there are forty-two Dasha system. However, out of forty-two, there are two very famous and popular namely “VIMSHOTARI” (120 years) and “ASHTOTTARI (108 years). In our analysis, we will be using the VIMSHOTTARI dash system.
Each Mahadasha is also sub-divided into Planetary periods called Antardasha or Bhukti and each Antardasha is subdivided into the Planetary period called Pratyantardadsha. For example, if the first Antardasha of Venus is Venus/Venus, the second is Venus/Sun, the third is Venus/Moon and so on. This subdivision gives more insight into what events are going to occur and when.
So let’s understand what is Mahadasha, Antardasha, and Pratyantardasha?
For example, In any country there is a Central government, then State Government and also County/district level government and for any individual who is staying in any district/county, he/she has to follow the decision made by all the three government. In the same manner, on any individual, all the planets ruled by Mahadasha, Antardasha, and Pratyantardasha give their effect.
The divisional longitude of each of the 27 nakshatras beginning with Ashwini and ending with Revati is 13 degrees and 20 minutes further divided into four quarters or padas. Each of the nine planets presides over a set of three nakshatras situated on the zodiac at a trine from each other. The commencing Dasha or mahadasha at the time of birth will be that of the lord of the nakshatra in which the Moon is placed, which particular nakshatra is known as the “Janma nakshatra”. If the Moon is in Taurus in Mrigsira the first Dasha will be of Mars, the second will be that of Rahu and so on.
The data of each planets give results as per their position in Zodiac sign/constellation, house, aspects and any yoga formed by planets. Using data system astrologer can come to know about Health, wealth, happiness, activity, age and the general well-being of human beings. However, here are the general effects of Mahadasha
