The analysis is an interesting combination of mathematics, astronomy and astrology.
As we have seen, the cosmos is divided in 12, in many ways. A kundali is made up of 12 houses, with 12 zodiacs and 12 planets placed in it based on the exact time and place.
A planet is placed at a particular degree and a Nakshatra, that is a constellation is attached to it.
There are 27 Nakshatras, each having a duration of 13 degrees 20 minutes each. These are further divided in 4, each quarter of 3 degrees 20 minutes each.
The planets are travelling in the 360 degrees of the sky. Now, each planet moves at a specific speed in its own orbit. Their distances from each other vary.
The different speeds make the travel time for each planet in the house of 30 degrees different.
The distance between 2 planets create particular ‘yog’. This yog influences on the characteristics and behavioural pattern of that particular set of planets.
Vimshottari dasha is another mathematical calculation used. It is done based on the planet degrees and the combination of the nakshatra. Total dashas are of 120 years and are owned by 9 planets.
