Dasa, as you know, is the period of time when one planet remains on a particular bhava(house)  for a particular amount of time. The planet which was dominant at the time of a child’s birth is of immense importance. While Maharishi Parashar has mentioned about 66 different Dashas while Jaimini suggested about 44 Dasa. But the one which is most predominant is Vimshottari Dasha. In fact, an astrologer must use more than one Dasa to get the best astrological results. Let’s study these Dasa systems. 

Using Dasa Systems 

Dasa systems came into existence so that when reading horoscopes one must take into account all favorable parametres and transits. If you see a particular situation, like loss of life or wealth or health from only Vimshottari perspective then you will fail more often than not. Therefore, Maharishi Parashara suggested the use of different Dasa systems to study particular conditions and circumstances in life. For example, Kaal Chakra or Niryana Shoola Dasha is used for predicting mishappenings, sickness or death, etc. Similarly, Chatursheeti Sama Dasha is used for reading the horoscope of a person whose 10th lord is in the 10th house. While you use Shasti Hayani Dasha when Sun is in lagna. Some of these Dasas are Rashi based and some are nakshatra based.
