Introduction
2

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

Section 1
Concept
5

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.

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 Sthanabalais based
on the placementof
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.
9

SthanaBala.SaptaVargajaBa
la
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 Dikbalais 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.

The Kalabalais based on the
period of timesuch 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.HoraVaraMasaAbdaB
ala 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.HoraVaraMasaAbdaB
ala 2
Hora Lordis the Graha ruling the hour. It is strongest among all.
Vara Lordis the Hora Lord at the moment of Sunrise. It is 2nd in
strength.
Masa Lordis 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 Lordis 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

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

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

Section 2
Computation
26

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.
27
Max = 60, Min = 0

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 Planetunder 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.
30

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
35
Max = 60, Min = 0

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

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.HoraVaraMasaAbda
Bala
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 minwhich equals to 24 degof maximum declination.

Steps for determining Ayana Bala (2/3)
(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.

Steps for determining Ayana Bala (3/3)
(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.

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.

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.

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.

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.

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.

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.

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.

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.

Conclusion
71

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
Phaladeepika 4.9 (b)
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
Phaladeepika 4.5 (b)
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.
