Sudarshan chakra :

Parashara describes a special chart that allows to analyze us the chart from the Lagna, the Moon and from the Sun . This chart is called the Sudarshan chakra . It is drawn in a round format . It is depicted in the Sudarshan Chakra report .
Each house is read from the Ascendant, from the Moon and from the Sun, to create a comprehensive analysis from multiple points of reference .
Sudarshan chakra should only be used when the Ascendant, Sun and Moon are all in different signs .
The Sudarshan chakra can also be used to make yearly, monthly and daily predictions . Every house is given a dasha period of 1 year . In the 1 st year of life the Ascendant has its dasha, in the 2nd year the 2nd house has it’ s dasha etc . At the age of 12 , the Ascendant will again have a dasha of a year, and so on . Within each dasha, there are 12 antardashas of one month each . The first month is the antardasha of the house that is running the dasha . The second month is the antardasha of the 2nd houses as counted from the mahadasha, etc .
Each month is again divided in 12 Pratyantardashas of 2 ½ days . The first Pratyantardasha is the same as the antardasha, the second is the 2nd house as counted from the antardasha, etc . Finally, each Pratyantardasha of 2 ½ days is divided in 5 hour intervals ( 12 ½ Ghatikas).
The interpretation of the Sudarshan dasha is based on the placement of the Grahas as counted from the house that is running its dasha .
