Mathematics of Astrology

Divisional charts are additional harmonics of a horoscope. These are calculated from the planetary positions of Lagna (ascendant) and the longitudes of all the other planets in a kundali.

The Shadbala system of calculating strength takes the guesswork away from such an interpretation and brings it down to mathematical formulae. There are no more ambiguities left. The unit of strength of a planet in this system is called a “rupa”. A rupa is further divided into 60 virupas or shashtiamshas (literally translated as sixty divisions).

There are 6 main strength areas defined by Continue reading
