The Sixfold Source of Planetary Strength ( Shad Bala )
We have said that Vedic Astro Physics is the
integration of 3 sciences -
Siddhanta ( Astronomy), Samhita (
Philosophy & Maths) & Hora ( Astrology ).Astronomy or
Siddhanta is the base, the scientific aspect and Astrology or Hora
is the predictive aspect of that infinite ocean which is the
Science ofTime, Vedic Astro Physics !
60 Shashtiamsas constitute a Rupa, a unit of
planetary strength. A planet
in order to be powerful should
get a minimum of Shashtiamsas. For example, Jupiter should have
at least 390 Shashtiamsas to be considered powerful. If he
attains a Shad Bala of less than 390, he is considered Vibala or
weak. Remedial measures have to be done for such a weak planet.

In assessing the strength of a planet, many
methods are used.
There are six kinds of potency in the Sixfold Method. They are
The calculation of each of these involves a fairly good knowledge
Application of the Sixfold
Strength or Shad Bala
The aphorism " A strong
planet will do good; a weak planet only harm " rules
Astrology. It is
common sense that weak planet weakens the houses he owns &
the significations which he signifies.
A planet's strength and weakness is
measured numerically by the Shadbala Method.
In short, Shad Bala method is the base of Vedic Astrology, as
the strength and weakness of a planet via the Sixfold Method.
1) Positional Strength ( Sthana Bala )
A planet may be placed in inimical, neutral
or friendly houses. It may be exalted or debilitated.
If he be in an inimical house, he is considered weak and he is
if in a
friendly house. This potency is known as Positional Strength or
Positional Strength consists of 5 major factors
1) Exaltation Strength
( Oocha Bala )
2) Strength in the Sevenfold Division
( Saptavargaja Bala )
3) Strength acquired in Odd & Even Signs (
Ojayugmarasyamsa Bala )
4) Angular Strength
( Kendra Bala )
5) Decanate Strength
( Drekkana Bala )
The strengths of planets are measured in Rupas. A Rupa consists of
1) Exaltation Strength - Occhabala
Occhabala is the Exaltation strength.
For instance,the largest planet Jupiter is
deeply exalted at 5 degrees Cancer. At 5 degrees Cancer, Jupiter
full strength of 60 Shashtiamsas or a Rupa. All planets have
certain Exaltation points ( Oochabhagas ) & Debilitation Points
( Neechabhagas ).
When a planet occupies its Oochabhaga,
it gets One rupa or 60 Shashtiamsas of
Oochabala. On the contrary, when it occupies its Debilitation Point(
Neechabhaga ), there is Zero Oochabala. There is a gradual increase
of Exaltation Strength
from the Debilitation Point ( Neechabhaga) to the Exaltation
Ucchabhaga ) , until at last the Bala reaches its maximum at the
there is a gradual decrease of Oochabala from the Exaltation
the Debilitation Point till the minimum is reached at the
( Neechabhaga ) .
Deduct the Debilitation Point from a planet's longitude and you
Oocchabala. If it is in excess of 180
degrees, deduct it from 360 degrees &
divide the difference by 3. This will give
the Oocchabala of the planet.
This is the formula for Occhabala
Oochabala = (Planet's Longitude - Its
Debilitation Point) * 60/180
( Planet's Longitude - Its Debilitation Point ) / 3
Relations between Planets
Planets are related to the Houses which they
own and which they tenant. They are
also related to the 16 types of divisions, Shad Varga ( known
as Divisional Charts
). Amongst the planetary members, certain planets are friends,
neutrals. There are two types of relationships between them. They
are natural relationships &
The planet in the 2nd, 3rd, 4th, 10th,
11th and 12th houses from any other planet becomes
his temporary friend. Those in the rest of the houses are
Combined or Mixed Relations
When a temporary friend becomes a natural
friend, they both become intimate friends. A
neutral is the combination of a natural friend & a temporary enemy and
bitter enemy is he who is a temporary enemy plus a natural
enemy. When we fuse these
principles, we get the following equations.
