Ashtakavarga:
This system is explained by B.V.Raman in his book, "Ashtakavarga System of Prediction".
Let's have a quick explanation about it.
Each sign is said to be good or bad, depending of the location of the seven visible
planets and ascendant in the birth horoscope.
We must consider the quality of each sign from the viewpoint of each planet. We say that
we are in the asthakavarga of this planet.
For example, in the Sun Ashtakavarga, the signs 1, 2, 4, 7, 8, 9, 10, 11 from the sign
occupied by Sun get one bindu, or good point.
The same principle applies to other planets, giving for each sign a total of good points.
Bindus are subject to reduction. Hindus use bindus before or after reduction for
different interpretation purposes.
For example, in his book, BV RAMAN says that the number of bindus, after reduction, in the
third sign from Mars in its own ashtakavarga gives the number of brothers or sisters of
the person.
Lunar periods and sub-periods
Concurrently with the above system, Hindus divide the life in 9 periods ruled by the seven planets plus Rahu and Kethu.
They are Kethu (7 years) Venus (20 years) Sun (6 years) Moon (10 years), Mars (7 years) Rahu (18 years) Jupiter (16 years) Saturn (19 years), Mercury (17 years), total 120 years, normal duration of the live according to Hindus.
Those big periods are known as Dasas.
First Dasa period relies on the location of Moon in sign (fixed sign) at birth time.
Each Dasa is in turn divided in 9 sub-periods called Bhuktis. Bhuktis follow the same order than Dasas, the first Bhuktis period is ruled by the lord of the Dasa.
Each Bhukti is in turn divided in 9 sub periods called Antaras, following the same principle that Dasas and Bhuktis.
In order to make a prediction for a given period, lords of Dasas, Bhukti, Antaras must be taken in consideration.
