BPHS 27.37-38.
O Brahmin, the various sources of
strengths should be gathered together
and effects declared. Whatever Yogas,
or effects have been stated with
respect to a Bhava, will come to pass
through the strongest Graha.
3

Saravali 4.34.
To assess the auspicious and
inauspicious effects of a planet, its
directional, positional, temporal and
motional strengths are important, for
without these it is considered to be
weak.
4

A graha acuires strength in various ways,
such as being placed in a certain rasi,
bhava, varga, day or night time, shukla or
krsna paksha, winning a planetary war etc.
Shadbala is a mathematical model to
quantify the strength attained from 6
different sources.

Drgbala
Some strengths are
combination of few
different kinds. For
instance Sthana
and Kala bala
comprises of many
sub-strength which
build up their overall
strength.

The Sthanabala is based
on the placement of Grahas
in certain Rasi, Bhava,
Drekkana and Varga.This
represents the Place factor.
8

SthanaBala.UcchaBala
This indicates how far a Graha is situated from its
Uccha-sthana-sphuta or the deepest exaltation
point.
Closer a Graha to its exaltation point, stronger it is
as per UcchaBala.

Shadbala

SthanaBala.SaptaVargajaBala
This indicates the strength of a Graha in 7
(sapta) divisions (varga) viz., Hora, Dreshkana,
Saptāńśa, Navāńśa, Dvadashāńśa and
Trimshāńśa
10

SthanaBala.OjaYugmaBala
Female planets in female signs and male planets in
male signs are given this strength. This is to be
judged in both Rāśi and Navāńśa charts.
Here, Venus & Moon are considered female and
rest are considered male.
11

SthanaBala.KendradiBala
The 1-4-7-10 are called Kendra (Quadrant), 2-5-8-11 are
called Panaphara (Succedent) and 12-3-6-9 are called the
Apoklima (Precedent Houses).
Planets in Kendra are strongest and in Apoklima are
weakest. Those placed in Panaphara have middling
strength.
12

SthanaBala.DreshkanaBala
Male grahas (Sun,Mars,Jupiter) get full strength in 1st Drekkana*. Female
planets (Moon & Venus) get full strength in 2nd Drekkana. Eunuch
planets (Saturn, Mercury) gets full strength in the 3rd Drekkana of a sign.
Saravali 4.38. Drekkana Bala. Male planets are strong in the first
decanate, female planets in the third decanate and neutral planets in the
second decanate of a Rāśi. Planets are strong, only when they are away
from the Sun, as per Yavanas.
13
*According to Parashara, the 1st Drekkana of a sign falls in the sign itself. The 2nd Drekkana falls
in the 5th from it and the 3rd Drekkana falls in the 9th from its placement.

The Dikbala is based on the placement of
Grahas in one of the four Kendras representing 4
directions (Dik).
Lagna represents the East and Guru, Budha
attains Dikbala here.7th house represents the
West and Shani attains Dikbala here. 10th house
represents the South and Surya, Mangal attains
dikbala here. 4th house represents the north and
Chandra-Shukra attain Dikbala here.

Shadbala
The Kalabala is based on the
period of time such as Day, night,
Year, Month, Hour, Fortnight etc.
in which a Graha becomes
stronger. This represents the
Time Factor.

KalaBala.NathonnataBala
Some Grahas are strong during daytime while some are strong at night time. This strength is
based on this concept.
Sūrya, Guru and Śukra gets this strength highest near to the Noon time. On the other hand
Chandra, Mangal and Śani gets strength highest near to the Midnight time. Mercury is strong
throughout the day. At other times, their strength is proportionally reduced.
Saravali 4.36. The Sun, Jupiter and Venus acquire strength during day-time, while Saturn, the
Moon and Mars become strong during night-time. Mercury acquires vigour at all times.
16
The Day-Night strength

KalaBala.TribhagaBala
When the Day and Night each are divided by 3, the 6 grahas (excluding Guru) gets
this strength in various portions of the Day.
Budha, Sūrya and Śani are strong in the 1st, 2nd and 3rd portion of the day-time.
Similarly Candra, Śukra and Mangal get full strength in the 1st, 2nd and the 3rd
portions of the night-time. Guru is strong through all the portions.
Saravali 4.39 The Moon, Venus and Mars get this strength in the first, second and
third parts of the night, respectively. This is similarly enjoyed by Mercury, the Sun
and Saturn in day-time, while Jupiter has it always, irrespective of day, or night.
17

KalaBala.PakshaBala
Some Grahas are strong during Shukla Paksha while others are stronger during Krsna Pasha.
The Shubha Grahas Chandra, Budha, and Guru and Śukra gets highest on this strength during
Purnima. The Krura Graha gets highest on this strength during during Amavasya. At other times,
this strength is proportionally reduced.
Saravali 4.36. Malefics get strength in Dark Half, while benefics become strong in Bright Half.
18

KalaBala.HoraVaraMasaAbdaBala 1
There are four component of this strength each of them is 25% stronger than the previous one.
The components are Hora (Planetary hour), Vara (Vedic weekday), Masa (Solar month) and
Abda (Solar year).
Saravali 4.36. The Hora Bala goes to Hora Lord, Masa Bala (Masa - month) to the Lord of the
month, Dina Bala to the Lord of the week-day of birth and Abda (year) Bala is credited to the
Lord of the year of birth.
19

KalaBala.HoraVaraMasaAbdaBala 2
Hora Lord is the Graha ruling the hour. It is strongest among all.
Vara Lord is the Hora Lord at the moment of Sunrise. It is 2nd in strength.
Masa Lord is the Hora lord at the moment of Transit of Sun* into a zodiac
sign. Month = duration of Sun’s Transit through one Zodiac sign i.e.,
between two Sankrantis.
Abda Lord is the Hora lord at the moment of Transit of Sun* into Aries.
20
* The definition of a year based on duration of 4,32,000 years in one Maha-yuga. Although some believe that the year definition should be
based on Soli-Lunar calendar as Chaitra Shukla Pratipada. However, in my opinion, since the original definition of time is based on Yuga,
we should take the definition of year and month based on the same principle.

KalaBala.AyanaBala
This Strength depends on the Uttarayana or Dakshinayana movement of Grahas.
Jataka Parijata Ch 2 mentions that Moon and Saturn are strong in Dakshinayana
(southern movement) and Sun and Jupiter are strong in Uttarayana (northern
movement).
According to BPHS Ch 27, Candra, or Śani are strong in southern Kranti
(declination), while when Sūrya, Mangal, Guru, and Śukra are strong in northern
Kranti. As far as Budha is concerned, is strong in both Uttarayana and
Dakshinayana.
21
R Santhanam in his book BPHS suggested the following formula for computation of the Ayana Bala
Ayan Bal = 60*(23°27’ + Kranti)/(46°54’) = (23°27’± Kranti)*1.2793.

KalaBala.YuddhaBala
BPHS 27.20. Should there be a war between
the Tara Grahas, the difference between the
Shadbalas of the two should be added to the
victor’s Shad Bala and deducted from the Shad
Bala of the vanquished.
22

ChestaBala
Chesta means effort. This source of strength means how much effort a Graha
is making. The effort is less when the Graha is moving steadily, and highest
when it is Retrograde. Retrogression can be equated with moving against the
river current, which is extremely tough.
Movement of Sun and Moon are always steady, and they never have
retrogression or acceleration, hence their Chestabala equates to their Ayana
Bala and Paksha Bala respectively. For the Tara Grahas (Mars to Saturn), their
Chestabala is computed based on their speed and direction of their motion.
23

Shadbala

NaisargikaBala
The natural strength of Grahas is called Naisargika Bala. The Grahas are progressively
stronger in the order of Śani, Mangal, Budha, Guru, Śukra, Candra and Sūrya, respectively.
When two Grahas influence each other by conjunction or mutual aspect, the one who is
stronger in this order has higher ability to influence the other and give results predominantly
of its own. Since Sun is the strongest, any Graha conjoining with the Sun becomes
Combust, but Sun does not become weaker.
Saravali 4.40. Saturn, Mars, Mercury, Jupiter, Venus, Moon and Sun are stronger than the
other in the ascending order. Should there be similarity in other strengths, then the one with
greater natural strength prevails.
24
5
Shadbala

DrgBala
Drg means aspect.This strength is acquired by the virtue of
being aspected by Natural Benefic or Natural Malefics.
The Aspect of Natural Benefics add to the strength, while that
of Natural Malefics reduces the strength.
The strength of aspect depends on the longitudinal difference
batween the aspecting Graha and the aspected Graha.
25

Shadbala

SthanaBala.UcchaBala
When a Graha is placed in its Highest exaltation, it gets 60 virupas and in its Deepest debility, it gets 0
virupas. At other places, the strength is proportionally reduced. To compute this, one need to determine the
longitudinal difference between the planet position and the deepest debility point and divide that by 3. The
value arrived is the Ucchabala of the Graha in Virupas.
If a Graha is placed in its deepest exaltation point, then the difference will be 180, when divided by 3, it gets
60 Virupas.
Visual estimation: Count the number of signs from the debility sign and subtract by 1, where the Graha is
placed. Add 10 virupas for each sign elapsed. For instance, for Sun, Libra is its debility sign. If Sun is placed
in Leo, counting from Leo to Libra, we arrive at 3 signs. Subtracting 1, we get 2. Multiplying 10 with 2, we get
20 virupas as the approximate stanabala for Sun.

Shadbala

SthanaBala.SaptaVargaja
This strength is dependent on the Placement of a Graha in one of the 6 states defined by the
compound friendship and enmity (Panchadha maitri) and its own sign. There is a 7th state,
which is placement in its Mulatrikona Rasi is only applicable in the Rasi chart (D1).
The SaptaVargas consists of divisions D1, D2, D3, D7, D9, D12, D30.
First we need to determine the Composite Friendship of the Planet under consideration with
other Planets from their Placement in the Rasi chart. Then we check whether the planet it
placed in its friend’s or enemy’s sign in various Vargas.
In this computation, there is no concept of Mulatrikona in the Varga chart. Also, exaltation sign
has utility in any Varga, as only thing to look for is the relationship of the Graha with other
Grahas as per the 5 point composite friendship.

Mitra 15 15
Sama 7.5 7.5
Shatru 3.75 3.75
Adhishatru 1.875 1.875
The maximum strength possible for any Graha to attain here is 45 (in Rasi) + 30 (in other vargas) * 6 = 45 +
180 = 225 virupas. The minimum possible is 1.875 * 7 = 13.13

BPHS 27.2-4. SaptaVargaja Bala.
When a Graha is placed in its Mulatrikona Rāśi, it gets
45 Virupas, in its Swakshetra (Svastha) it gets 30
Virupas, in its Great Friend’s Sign (Pramudita) it gets
22.5 Virupas, in a Friendly Sign (Shanta) it gets 15
Virupas, in its neutral Sign (Dina) it gets 7.5 Virupas, in
its Enemy’s Sign (Duhkhita) it gets 3.75 Virupas and in
its Great Enemy’s sign (Khala) it gets 1.875 Virupas
Ref: Bhava & Graha Balas by Dr. BV Raman.
29

BPHS 3.55. Naisargika Sambandha. Note the Rāśis, which are the 2nd, 4th,
5th, 8th, 9th and 12th from the Mulatrikona of a Graha. The Graha is friendly
towards the Grahas ruling such Rāśis, and also to the Lord of its exaltation Rāśi.
The Graha is inimical towards the lords other than these. If the Graha becomes
friend as well enemy towards someone, then it becomes neutral to that Graha.
BPHS 3.56. Tatkalika Relationships. The Grahas, posited in the 2nd, 3rd, 4th,
10th, 11th, or the 12th from another, become mutual friend. There is enmity
otherwise.
57-58. Panchadha Sambandha. Should two Grahas be both naturally and
temporarily friendly, they become Adhimitra (extremely friendly). Friendship on one
count and neutrality on another count make them Mitra (friendly). Enmity on one
count combined with friendship on the other turns into Sama (neutral). Enmity and
neutral-ship cause only Shatru (enmity). Should there be enmity in both manners,
Adhishatru (extreme enmity) is obtained. The Jyotishi should consider these and
declare horoscopic effects accordingly.

SthanaBala.OjaYugmaBala
Female (Venus & Moon) planets in female signs and male
(Sun, Mars, Mercury, Jupiter & Saturn) planets in male signs
are given this strength. This is to be judged in both Rāśi and
Navāńśa charts.
In each of Rāśi and Navāńśa charts a Graha gets 15 Virupa,
so maximum strength possible is 30 Virupa.
31
Max = 30, Min = 0

SthanaBala.KendraBala
Planets in Kendra are strongest (60 virupas)
and in Apoklima (15 virupas) are weakest.
Those placed in Panaphara (30 virupas) have
middling strength.
32
Max = 60, Min = 15

SthanaBala.DreshkanaBala
Male grahas (Sun,Mars,Jupiter) get full strength in first
Drekkana. Eunuch planets (Saturn, Mercury) gets full
strength in the middle Drekkana of the sign. Female planets
(Moon & Venus) get full strength in last Drekkana.
Maximum possible Drekkana Bala is 15 virupas while
minimum is Zero.
33
Max = 15, Min = 0

Sthana Bala Summary
Maximum Minimum Average
Uccha 60 0 30
Saptavargaja 225 13.13 119
OjaYugma 30 0 15
Kendradi 60 0 30
Drekkana 15 0 7.5
Total 390 13.13 201.5

DikBala
When A Graha is placed in the Dika (Direction) where they belong to, the
attain 60 Virupa of strength. In the opposite sign, they attain 0 Virupa of
strength. In other Bhavas, their strength is proportionally allocated based
on their placement with regards to the Bhava where they attain Dikbala.
The Bhava Graha combination where dikbala is attained are:
Lagna: Guru/Budha | 4H: Chandra/Shukra | 7H: Shani | 10H: Surya/Mangal

Shadbala

BPHS 27.7-7½. Dikbala.
Deduct Sukha Bhava (Nadir) from the longitudes of
Sūrya and Mangal, Saptama Bhava from that of
Guru and Budha, Karma Bhava from that of Śukra
and Candra and lastly Lagna from that of Śani. If the
sum is above 180 degrees, deduct the sum from
360.
The sum arrived in either way be divided by 3, which
will be Dikbala of the Graha.
36

KalaBala.NathonnataBala
Sūrya, Guru and Śukra are strong during the day with Peak at the Noon. On the other hand
Chandra, Mangal and Śani are strong with their peak at the Midnight. Mercury is strong
throughout the day. At other times, their strength is proportionally reduced.
The Maximum attainable strength here is 60 virupa which is during the peak time. Mercury has
always 60 virupa of strength.
37
The Day-Night strength
Max = 60, Min = 0

Shadbala

KalaBala.PakshaBala
The Pasha Bala is derived from Shukla and Krsna Paksha of Moon
phase. Subha Grahas are Jupiter, Shukra, Waxing Moon and Mercury
devoid of Papa conjunction. On the other hand Papa (Krura) grahas
are Sun, Mars, Saturn, Waning Moon and Papa conjoined Mercury.
Shubha Grahas get 60 virupa during Purnima and 0 during Amavasya.
The reverse is true for Papa Grahas. The Sum-total of the Subha and
Papa Graha Pasha Bala is always 60 virupas.
38
Max = 60, Min = 0

KalaBala.TribhagaBala
A Graha gets Tribhaga Bala at Certain portion of day and
night when each of them is divided into 3 portions (Bhagas).
The highest achievable bala is 60 when the Graha is placed
in their own portion (Bhaga). Guru always gets 60 virupas as
Tribhaga Bala.
39
Max = 60, Min = 0

KalaBala.HoraVaraMasaAbdaBala
The abda bala of a Graha is 15, Masa Bala is 30, Vara Bala is 45 and Hora Bala is 60 virupas.
A Graha gets this strength when it gets to rule over the mentioned Time periods i.e., Year,
Month, Day or Hour.
The Maximum strength that can be gained here is 60 + 45 + 30 + 15 i.e., 150 virupas. It is
possible, only when a Graha rules all the 4 period at one time.
40
Max = 150, Min = 0

KalaBala.AyanaBala
The Ayana Bala depends on the Declination (Kranti) of the Graha. When the Graha
move up in Declination, it is called Uttarayana and on the Reverse is called
Dakshinayana.
The Ayana Bala at Zero Declination is 30.
For Moon and Saturn, at lowest Declination, Ayana Bala becomes 60 and in highest
Declination, it becomes Zero. This is reverse for all other Grahas viz., Shukra, Surya,
Mangal and Guru.
Ayana Bala** = (240 + Kranti)/ 48 * 60
41
Max = 60, Min = 0

Maximum declination is
23 deg 27 min and this
is rounded to 24 by
Vedic savants for ease
of computation.
42

Steps for determining Ayana Bala (1/3)
(1) Sayana Longitude: Convert Nirayana to Sayana Longitude by adding
Ayanamsa
(2) Bhuja: Bhuja is the distance from the nearest Equinoctial point. The
Equinoxial points are at 0 deg (Aries) and 180 deg (Libra).The
maximum attainable Bhuja is 90 deg.
(3) Portion of Declination: The highest declination of 24 deg (approx. of
23 deg 27 min) is divided into 6 portions, each measuring 15 degrees
of Bhuja. The Bhuja should be divided by 15 to determine the portion
in which the Bhuja falls. Here the Quotient represents the portion of 15
degrees and the Reminder represents the extent of progress of the
Graha within the Portion. So Portion = Quotient, Deg Elapsed = Remainder.
(4) Declination Associated with the Portion: Each portion of 15 degrees is
associated with a Declination value. They are 1st portion: 362 min,
2nd portion: 341 min, 3rd portion: 299 min, 4th portion: 236 min, fifth
portion: 150 min, Sixth portion: 52 min. When the declinations
allocated to various portions are added up, we arrive at 1440 min
which equals to 24 deg of maximum declination.

(5) Declination within the Portion: The Maximum declination within a portion
is given before. So declination within a portion can be ascertained by
Declination with the portion (in minutes) = (Portion.Declination * Elapsed) / 15
Portion.Declination = 362 (1st), 341 (2nd), 299 (3rd), 236 (4th), 150 (5th), 52 (6th). The Figures inside the bracket represent
the portion while those outside are the max. declination in that portion.
(6) Total Declination: The total declination is the sum of Declination arrived in
15 deg portion of the Bhuja and the total declination of previous portion.
(7) North Vs. South Declination: If the Sayana longitude is below 180 degree,
it is Northern declination. On the other hand, if the longitude is more than
180 degree, it is Southern declination.

Uttarayana (Northern Course) Dakshinayana (Southern Course)
By knowing the Sayana Rasi and Longitude of a Graha, the computation can be easily performed using the table mentioned below.

(6) Determine the Ayana Bala: According to Keshava Daivagna, the Ayana
Bala can be found using the following formula
Ayana Bala = (24 deg +/- Declination value) / 48 * 60
Whether the Declination value is added or Subtracted in the formulas
depends on the Graha and their south or north declination. Moon and
Saturn are strong in Southern declination, hence their declination value is
added when they are in south (Libra to Pisces in Sayana chakra). If they are
in the Northern declination (Aries to Virgo), their declination value is
subtracted. This is reverse for the remaining Graha. Mercury’s declination is
always added irrespective of whether it is in South or North.

KalaBala.YuddhaBala (1/2)
Two planets are supposed to be in Planetary War when distance between
Two Grahas is less than 1 deg. The one in the North is victorious.
Only the Tara Graha (Mars, Mercury, Jupiter, Venus and Saturn) get into
war. Planets conjoining Sun get into Combustion and those conjoining
Moon get into Samagama.
The quantum of Yuddha Bala = Difference in the total of Tri-balas (Sthana,
Dik, Kala) / Difference of disc circumference.

KalaBala.YuddhaBala (2/2)
The YuddhaBala has to be deducted from the Kalabala of
the defeated planet and added to that of the Victor. The
resultant Kalabala is the final Kalabala used for all purposes.
In the Kalabala, Natonnata, Paksha,Tribhaga and Abda-
Masa-Vara-Hora bala are included. Here Ayana Bala is
excluded.

Chesta Bala
The Chesta Bala can be known from the speed of the Grahas. The
computation involve determining the mean position and the true position and
identifying the difference to determine the speed. The computation is complex,
hence an approximate method is suggested. The Approximation will introduce
only a small error in Shadbala as its maximum contribution is only 60 virupas.
The rate of change of longitude can be determined from any standard
ephemeris of astrological software and compared with the average speed.

The strengths, allotted due to such 8 motions are 60 (Vakra),
30 (Anuvakra), 15 (Vikala), 30 (Manda), 15 (Mandatara), 7.5
(Sama), 45 (Chara) and 30 (Atichara).

BPHS 27.21-23.
There are eight kinds of motions are attributed to
Grahas. These are Vakra (retrogression),
Anuvakra (entering the previous Rāśi in retrograde
motion), Vikala (devoid of motion), Manda (slower
than usual), Mandatara (even more slower), Sama
(neutral motion), Chara (faster than Sama) and
Atichara (entering next Rāśi in accelerated
motion).
The strengths, allotted due to such 8 motions are
60, 30, 15, 30, 15, 7.5, 45 and 30.

NaisargikaBala
The natural strength of Grahas is called Naisargika Bala. The Grahas
are progressively stronger in the order of Śani, Mangal, Budha, Guru,
Śukra, Candra and Sūrya, respectively.
Saravali 4.40. Saturn, Mars, Mercury, Jupiter, Venus, Moon and Sun
are stronger than the other in the ascending order. Should there be
similarity in other strengths, then the one with greater natural strength
prevails.

Drg Bala
When a Natural Benefic (Jupiter, Venus, Waxing Moon and Benefic Mercury)
aspects a Graha, it adds to their strength.
On the other hand, when Natural malefic (Saturn, Mars, Sun, waning Moon
and Malefic Mercury) aspects a Graha, it reduced their strength.
The computation of this strength is time-consuming, hence an approximation
has been suggested. This will introduce some insignificant error, which can
be ignored.

When the Aspecting “Benefic Graha” is placed in a
certain house from the aspected Graha, Add figures
mentioned in the House in the diagram.
Instead, when a “Malefic Graha” is aspecting a Graha
from another Bhava, Deduct figures mentioned in
House in the Diagram.
Rider: Guru’s 5/9 aspect should be taken as 7.5.
Saturn’s 3/19 aspect should be taken as -11.25 and
Mars’s 4/8 aspect should be taken as -3.75.

600 - 900 (DK - 600) / 4 + 3.76
300 - 600 (DK - 300) / 8
1. Determine the Drsti Kendra
Drsti Kendra = Aspected Graha Longitude - Aspecting Graha Longitude
2. Based on the Drsti Kendra, determine the Drsti Bala
Depending on where the Aspecting Graha is situated (from the Aspected Graha), different
formula is applied to determine the Drsti Bala.
3. Add the Drsti Bala of Natural Benefics and Subtract that of Natural Malefics
Rider: Guru’s 5/9 aspect
should be taken as +7.5.
Saturn’s 3/19 aspect should
be taken as -11.25 and
Mars’s 4/8 aspect should be
taken as -3.75.

Using the formula provided in the previous
slides, the drsti bala is derived for various
Drsti Kendra (DK: longitudinal difference
between the aspecting and aspected planet).
Usage: Determine the 30 range where the DK
is falling. Determine the column associated
with that range.
After the range has been identified,
determine the DK elapsed from the
beginning of the range. Then, for the
combination of the Row and Column,
determine the Drsti Bala value
Example: Lets try determining, the Drsti Bala
for Surya who is aspected by Guru from 7th
house at192 from the Sun. 192 falls in the
range of 180-210. It is 12 degree away from
the beginning. So looking at 12 in Row
under, the 180-240 Column, we arrive at
+13.5. This is the Drsti Bala of Surya due to
Guru’s aspect.

Assessment of
strength

Assessment of Strength
The Stanabala and Kalabala individually
contribute to strength that is more that
combined strength of Dik, Chesta, Naisargika
and Drg.
The highest strength attainable under
Sthanabala and Kalabala is the same i.e., 390
virupas. The combined strength of the other four
balas are 240.

In a horoscope, if the strength of “a Graha” is low due
to its position in Bad Avastha, such as sign of Debility,
sign of enemy or great enemy, in Apoklima etc., it can
be compensated by Birth in a auspicious time when the
Graha under consideration is strong.
In general, it is excellent if the Lagnesha (LL),
Mantresha (5L) and Dharmesha (9L) are endowed
with Great strength either through Stanabala or
Kalabala, if not all the other strengths.

BPHS 27.34-36. Minimum Prescribed Strength
Guru, Budha and Sūrya are strong, if each of
their Sthanabala, Dikbala, Kalabala, Cheshtabala
and Ayanabala are, respectively, 165, 35, 50,
112 and 30 Virupas. The same required for
Candra and Śukra are 133, 50, 30, 100 and

If the strength exceeds the above-mentioned values, the
Graha is deemed to be very strong. If a Graha has the
required Shadbala, it will prove favourable to the native by
virtue of its strength. However, Śani’s extreme strength will
give long life as well as miseries.

It is always not possible to mathematically determine the
strength of the Grahas. However, a good understanding
of the conditions in which different Grahas attain strength
can help in quick visual estimation of strength.
The Authors of Jataka Parijata and Phaladeepika provided
their views on the circumstances in which Grahas attain
strength which is same as Parashara’s Shadbala model,
however, the focus is more on getting a sense of the
strength through quick visual estimation.
When one attains proper understanding of 6 sources of
strength, one does not need to rely upon complete
computation.

Special Strength of the Moon
Phaladeepika 4.21
It is said that Pakshabala (fortnightly strength) is of special importance to
the Moon, while the Bala arising from Sthana (position) is important for the
other planets.
This strength when added to the other varieties of strength of a planet will
greatly increase the strength of that planet. There are many such types of
strength.
75

Strength of Planets from Phaladeepika (1/2)
Phaladeepika 4.2(a)
The Moon gets Cheshtabata when she is full. The Sun gets it when he is
in his northern course; the other planets, when in their retrograde motion.
In planetary war, those that are posited in the north and who have got
brilliant rays should be considered as victorious.
Planets have their full Uchchabala when in their highest exaltation.
76

Strength of Planets from Phaladeepika (1/2)
Phaladeepika 4.2 (b)
As regards directional strength, the Sun and Mars are strong in
the 10th; Venus and the Moon in the 4th; Mercury and Jupiter in
the 1st and Saturn in the 7th.
Mercury, Saturn and the Moon have their Ayanabala in their
southerly course. The rest have the same in their northern.
77
Comments: According to Maharishi Parashara, only Moon and Saturn attain Ayanabala when in Southerly
course (Dakshinayana) and Mercury is strong in both the Ayanas. In my view Maharishi Parashara’s view
should be considered authentic in this regard.

Vargabala and Kendrabala
Phaladeepika 4.9 (a)
The strength accruing to a planet in the six Vargas (viz., Rasi, Hora,
Drekkana, Navamsa, Dwadasamsa and Trimasamsa) on a consideration of
its being posited in its exaltation, its own and its friendly signs etc., is
termed its positional strength.
That arising from its being in Kendra and other Bhavas (i.e., Phanapara and
Apoklima) will be one 1, ½ and ¼ Rupa respectively.
78

Drekkana bala and Naisargika bala
The hermaphrodite planets are strong in the middle, the male
ones at the initial and the female ones at the concluding portions
of a Rasi.
Saturn, Mars, Mercury, Jupiter, Venus, the Moon and the Sun are
in their order increasing in their natural strength.
79

Chesta Bala compensating for Stana Bala
Phaladeepika 4.4
A planet is said to possess strength when he is retrograde or when his rays
are full and brilliant, though posited in a depression or inimical Rasi or
Amsa.
Like the Moon, a planet though occupying an exaltation, friendly or his own
Rasi or Amsa becomes weak, should his rays be overpowered or eclipsed.
80

Special Strength of Moon and Sun
Phaladeepika 4.5 (a)
All planets are strong when they are in exaltation. The moon is
strong and auspicious when she has her full Paksha bala and the
Sun when he has his full Dikbala.
The other five non-luminous planets (Tara Graha) are strong when
they are retrograde (Chesta bala).
81

Strength of Rahu and Ketu
Rahu is strong in Karkataka, Vrishabha, Mesha, Kumbha and
Vrischika.
Ketu is strong in Meena, Kanya, Vrishbha and the later half of Dhanus.
It is also strong in Parivesha and Indra-chapa (through conjunction)
and at night when there is conjunction of the Sun and the Moon.
82

Bhava strength
Phaladeepika 4.6a
If the first Bhava be a Human sign (Manushya Rasi), 1 Rupa has to be
allotted to it; if it be Vrischika (Keeta Rasi), the Bala is ¼; if it be any
other sign, the strength is ½.
The strength of the Lagna is equal to that of its lord and is very powerful
when the lord occupies an Upachaya (3rd, 6th, 10th or 11th) house.
83

Day signs and Night signs
Phaladeepika 4.6b
The same is also the case when the Bhava is occupied or
aspected by Venus, its lord, Mercury or Jupiter, and is at the
same time without the conjunction or aspect of any other planet.
The day signs possess strength in day-births, while night signs
are declared powerful in night-births.
84
Comments: According to Phaladeepika 4.11, the strength of Guru is 1 rupa,
Budha is 1/2 rupa and that of Shukra is 1/4 rupa to ward off evil.

Positional strength in different signs (Avasthas)
Phaladeepika 4.7
A planet gets 1 Rupa as positional strength when he is in his
exaltation Rasi. The strength is ¾ when he is posited in his
Moolatrikona Rasi. It is ½ when the planet occupies his own Rasi.
When the planet is in a friendly house, his strength is only ¼. In an
inimical sign, he gets only very little. The strength is nil when he is in
his depression sign or eclipsed by the Sun’s rays.
85

Difference in strength between the Kendras
Phaladeepika 4.8
The strength of the planets occupying the 4 Kendras (1st,
4th, 7th and 10th) has been distinguished by the astrologers
in the following manner; It is ¼th in the 4th house; ½ in the
10th, ¾ in the 7th and full in the 1st or Lagna, thus increasing
it by ¼ in each stage
86

Strength of Aspect
Phaladeepika 4.9
The aspect from the 7th house is the only one that should be
declared as most effective in all cases; not so, the rest. But
there are others who opine that the special aspect (of Saturn,
Jupiter and Mars) is in no way less efficacious in producing
full effect in all Yogas and the like.
87

Stronger between Naisargika & Tatkalika
Sambandha
Phaladeepika 4.10
Natural enmity or friendship between two planets is more fully
effective than and preferable to their corresponding temporal ones
as the latter is only a variable quantity and not a permanent one.
88

Special power to block Inauspicious Results
Phaladeepika 4.11
In completely warding off evil and in promoting prosperity, Jupiter is the most
powerful of all the planets. Mercury and Venus have a ¼ and ½ respectively of
that power.
The Moon’s strength serves as a basis as it were for the strength of all the
planets.
89
Comments: Moon’s strength in any horoscope is paramount as when Moon is
endowed with strong Paksha Bala, it all the Grahas in the horoscope gain
strength to fight evils.

When a Graha considered strong?
Phaladeepika 4.22
The Sun is declared strong when his
strength is 6½ Rupas. In the case of the
Moon, it is 6½ Rupas. Five Rupas are
assigned to Mars and 7 to Mercury.
Jupiter's Purnabala is similar to that of
the Sun, that is 6½ Rupas. Venus is
strong when he gets 5½ Rupas.
Phaladeepika 4.23
Saturn should have 5 Rupas. These are
the figures representing the total
Shadbala for the several planets. If the
respective figures are less than the
mentioned, the planets should be
considered as weak.
90
It is only after a minute examination of the several kinds of strength (Shadbalas)
of the several planets, one ought to declare their effects.
