The Sudarshana Chakra is a brilliant and precise predictive chart described by Sage Parashara in the Hora Shastra. It comprises the Surya, Chandra, and Lagna charts erected in concentric circles or wheels. It is used to determine the full disposition of a natal or mundane chart. In addition, it is also employed in combination with transits and its own unique dasha system in natal and mundane predictive work.
