Analyzing Basics – Dasas (I)

Ok ladies and Gents. Coming to a crucial and a vast, deep topic of Dasas (planetary periods)

It is an ever-vital and indispensable tool of Jyotish in predicting the timing of future events.

Let me mention out-front, the topic is extremely wide and deep and in these tutorials (meant for the beginner) I will be giving only basic yet relevant information, which will arm the reader with the necessary tool missing in combination to her Transit tool. Once armed with both, you are on your way to be able to start making predictions which amaze yourself and your friend and family 🙂

So Dasas in Jyotish are of many kinds (JHora gives the option of about 50 or more of them!)

These differ by calculation methodology and applicability and frame of reference (planetary dasas, rashi dasas etc.). Here we are going to talk about the most frequently/ widely used dasas and that too briefly in the interest of time and the scope of this article.

Among the most commonly used dasas is the Vimshottari dasa (which is an almost default dasa an astrologer would refer to if he mentions the term ‘dasa’). As per Parasara, it is a dasa applicable to All across the board except a few exceptions as explained below-

Vimshottari is started/ calculated as per the exact longitude of Moon at the moment of birth. Moon as you know represent the mind, emotions, thought process/ intelligence among other things and is the primary significator of the above. This is one of the wider differences between Jyotish and other schools of astrology across the globe – Jyotish puts a heavier emphasis on the Moon, arguably due to the logic that whatever happens around us and with us, affects our feelings, emotions and thought process which are signified my the Moon and hence its importance. Also to be noted is the fact that the Moon is the fasted moving entity of the 9 planets and hence the most ‘specific’ differentiator  in terms of difference between 2 individuals born at relatively close time intervals. Moon takes about 2.25 days to cover one sign of 30 degrees whereas the Sun takes a month. Thus making the moon more specific than the Sun in this example.

Due to the above considerations, as per Parasara, as long as the mental faculties are developed meaningfully enough, Vimshottari dasa will always be applicable. Now of course the exceptions will be very young individuals (say below age 6 to 8 yrs) or extremely old individuals or individuals with an impaired mental ability like medical mental retardation etc. are the cases where Vimshottari might not be applicable. However as long as the native is older than 8 yrs. of age and mentally ‘not challenged’, Vimshottari will be applicable.

So lets discuss this dasa system. The moon covers 27 Lunar asterisms (nakshatras) and 12 signs in one revolution, like other planets. Moon takes about 28 days approximately for one such circle so it covers a little less than 1 nakshatra per day (roughly). 360/27 = 13 degrees and 20 minutes or 13 1/3 degrees (length of one nakshatra)

the Nakshatras, as mentioned before in an article are of the 9 planets (3 times each) and follow the order of Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury. Then repeat 2 more times the same order.

Once the exact degree of moon is known, it can be calculated that how far has moon progressed into that nakshatra. Lets assume moon is in Venus nakshatra at the time of birth and has travelled 3 degrees and 20 minutes in it. It implies that Moon has traversed exactly 1/4th of the Nakshatra of Venus and 3/4 remains. Now look at the following table for Vimshottari-

Sun – 6 yrs

Moon – 10 yrs

Mars – 7 yrs

Rahu – 18 yrs

Jupiter – 16 yrs

Saturn – 19 yrs

Mercury – 17 yrs

Ketu – 7 yrs

Venus – 20 yrs

For a total of 120 yrs. Vimshottari assumes a total of 120 yrs cycle for dasa. In the rare even that someone lives beyond 120 yrs, the dasa sequence will start again for a 2nd cycle.

So coming back to our moon which had traversed 1/4th of the Venus nakshatra, what it implies is that 3/4th of that is left OR 3/4th of the 20 yrs of Venus is left as a balance at the moment of birth or 15 yrs. So this native will have Venus dasha at the time of birth till his 15th birthday and then sun MD will start for 6 yrs, followed by Moon MD for 10 yrs etc.

The sequence and quantity of dasas is FIXED and never changes for any individual. Only the starting point changes as per Moon longitude at birth

So what we just described is called the Mahadasa or MD in short which is Level I dasa. Below this level will be level 2 dasa called Antar dasa or (AD). Below that would be 3rd level called Pratyantar Dasa (PD) and so on. Technically its a FRACTAL calculation which goes to infinite levels. But important to note is that even till level 6, you will reach a time frame which is already in minutes or hours (as opposed to years of Maha Dasa) and hence for all intents and purposes the first 3 levels are the most important. Finer levels can be used for fine tuning.

Next important point to note is that in each MD, the first AD will be the MD lord itself and then the next AD will be next planet in the sequence and so on. The time frame remains fixed as per the ratio of MD contribution. Pay attention here. What this means is- say Moon MD just started. First AD will be Moon itself and time frame will be in ratio of 10/120 (because Moon has 10 in the MD slot in the above table of a total of 120).

Next AD will be Moon/ Mars with a time 7/120th of the 10 yrs of moon MD or 7 months when you calculate
Next AD will be Moon./ Rahu with a time of 18/120 of the 10 yrs of Moon MD or 18 months when you calculate and so on till you reach Moon/ Sun of 6 months. After Moon/ Sun ends, the Moon MD of 10 yrs is over and you start Mars MD of 7 yrs and so on and so forth

Very much like the above, the 3rd level dasa will be the same as the AD lord itself and then from there. So Moon/ Moon/ Moon will be followed by  Moon/ Moon/ Mars then Moon/ Moon/ Rahu etc. (Again time frame in same ratio as described for AD above)


Good news is that the calculations are all done by the software, however one still has to understand the above logic and hence the ‘method behind the madness’

People with good mathematical skills will quickly realize a Fractal pattern in this, which for some reason is increasingly seen in nature in terms of Golden ratio etc. (beyond the scope of this discussion and hence I wont digress much)

Now once you know what dasa a person is running, keep the following factors in mind-

  • MD lord sets the Major trend in life
  • AD lord gives the finer trend within the MD period and is very important for a relatively shorter time frame
  • PD lord is usually a few months to a few weeks and PD and beyond levels are for fine tuning the effects of MD and AD lords
  • starting from MD lord, analyze what the MD lord planet rules in your horoscope (the bhaavs it rules) also analyze its dignity, aspects and placement in details as described in previous chapters
  • Do the same for AD lord and PD lord etc
  • Then analyze how the MD and AD lord are related to each other and use the compound friendship analysis as described in the dignity of planets article
  • Events are precipitated when the dasas indicate so and the transits also indicate in the same direction. Important now is to note what I mention in the Transit articles – transit of MD and AD lords and even PD lord is very vital as per description in those articles
  • As an overall ‘mantra’ Dasa Proposes, Transit Disposes. Hence correct prediction lie in the ability (developed over experience) in harmonizing the signs given by both. Ideally when you get more knowledge and experience, more than one dasa is also used to confirm results, but for now (and believe me for 99% of astrologers) Vimshottari is enough to prevent information overdose for the student.

I will write more points regarding dasas in the subsequent articles, but the reader can now start checking the dasa they are running in JHora by clicking on the ‘Dasas’ tab on the top of the software and selecting Vimshottari dasa among the ‘Nakshatra dasas’ tab in the feature. Click on the time period of an MD and a drop down will keep giving you lower levels of AD, PD etc. Try. Practice…

    Sri VS:
    If one has Sun MD and Sun is posited in Cancer does Sun “activate” the moon and its rasi/bhava? Say, for a Taurus asc Sun does good but if the Moon is afflicted..hence asking.

    Thank you

    • VS says:

      yes it does
      sun will give the bhaav results as well as the results of moon in the chart…meaning where moon is placed, how strong etc

  2. Sundar says:

    Can you give a small example of “MD proposes, Transit disposes”? would be helpful..thanks.

    • VS says:

      every reading you do is an example. Just start looking at any chart for events that have already happened. say someone brought a car. now look at the dasa and see how the 4th house, 11th house and/ or venus was involved. Once you see the planets in the horoscope and the dasa, then see the transit.

      transit alone can not give anything, good or bad. but if the chart has a promise in it and the dasas give the promise, then the transit is the one which finally triggers it on a day or weekly basis

  3. Sundar says:

    Sri VS:
    During Jupiter dasa, are all the bhaavs for which it is a full or partial kara affected?
    Are the effects of these bhaavs seen during the entire dasa or when Jupiter/AD planet aspects these karaka houses in transit?


  4. Sundar says:

    Sri VS:
    For MD analysis, is it correct to look at placement of the MD planet relative to its karak house (say is venus sitting nth from the 4th), and the placement from its MK house? (in addition to the posited house, aspected houses and aspected planets). I saw this analysis in a YTube video. Does this analysis yield any additional value?

    Thank you.
