Shad means six. Bala means strength. Hence Shadbala means six fold strength.
Why it is important?
Consider that you have a friend or relative who has no power. Will he be good for you? He is still your friend or relative. So it is very important to know who your favourable friends are and how strong they are.
If you have a Mahadasha and an Anthardasha the resultant effect will be the effect of the strong planet amongst the two.
The Bhava result will also be influenced by
1) The grahas in the Bhava
2) The grahas viewing the Bhava
3)The lordship of the Bhava
4)The significators or Karakas of the Bhava
Here also the strength of the planet will influence.
Sthana Bala -Positional Strength
This is the strength which a planet get as a result of occupying a particular sign in a horoscope. A planet gets its positional strength in its exaltation. Moola Thrikona, own house, friendly house, Swa Shadvargas etc. in debility the sthanabalam is zero.
We all know that we get respect and power in our own house or positions. There will no bala in an enemies house. Positional strength is the most important. It is further divided into 5 items namely.
Saptha vargaja Bala
This is obtained through the exaltation of planets.
Deduct Neecha from Grahasphudam. Divide it by 3, you get Uchabal. The maximum is 60 shashtyamsa or 1 rupa.
Maharishi Parashara supported for mathematical calculation of different strength.
Saptha vargaja Bala
The above 7 vargas or classifications are called Saptavargaja bala.
If a planet is in Moolathrikona, it gets 45 shashtyamsa, Swakshethra – 30 shashtyamsa and friendly house – 15 shashtyamsa .
Swagrahopagathaischa Varaha Acharya tells us that female planet get strength in female rasi, while male planet get strength in male signs.
Hence Venus and Moon get 15 shashtyamsa strength in female rasi and navamsa.
The first, fourth, seventh and tenth signs are called Kendras.
Very important among positional strength. If in the centre, planet gets 60 value while in panaparam meaning 2, 5, 8 and 11, they get 30. In 3, 6, 9 and 12 they get only 15 points.
Ojayugma bala(sthana bala -positional strength)
Mercury and Saturn the Shanda Graham, get strength in the Madhya Drekkana, Moon and Venus get strength in last Drekkana while others get strength in first Drekkana . Points is 15 only. A total of all the above Socha Suhrud Swa Drigaana Navamsair is the sthana bala.
Digbala -Directional strength
This is the directional strength.
In lagna, the ascendant(East), Mercury and Jupiter are powerful. In 10th Bhava (North) Sun and Mars are powerful. In 7th Bhava (west) the Saturn is powerful. In 4th Bhava (south) Moon and Venus are powerful.
Sage Parashara has detailed mathematical calculation of Digbala. Deduct Balasoonya Dig Sthana sphudam from the graham and divide by 3.You get directional strength in points. Maximum is 60.
Cheshtabala- Motional strength
From Makara (Capricorn) upto Midhuna is Uttarayana (Sun’s Northenly course). Sun and Moon are powerful in this period. Mars, Mercury, Jupiter, Venus and Saturn in retrogression or in conjunction with full Moon get Cheshta bala.
In order to find out Cheshtabala mathematically, we have to find a result namely Cheshta Kendra and divide it by 3.
Dina Rathri Bala
It means temporal strength. the Moon, Mars and Saturn are powerful during night. Sun, Jupiter and Venus are powerful in day. Mercury is powerful in day and night it is called Dina Rathri Bala
The maximum bala is 60 shashtyamsa. For Moon, in midnight bala will be 60, so is for Sun in midnoon.
It means for benefic planets, the end of Sukla Paksha is powerful. But for malefic end of Krishnapaksha is powerful.
If we divide day time into 3, Mercury is the lord of first part, Sun the lord of second part and Saturn is the lord of 3rd part. Similarly night time is given to Moon, Venus and Mars. Guru is always powerful. A maximum of 60 is given.
Abda bala, Masa bala, vara bala, and hora bala
There are Abdabala for the starting day of the year, similarly Masa bala for the month starting vara lord, Vara bala for the Vara lord and Horabala for Kaala Hora lord.
Hora bala is the maximum in Kalabala and is with 60 points
This means natural strength. each planet is supposed to produce a particular measure of strength permanently irrespective of its position. Sun, Moon, Venus, Jupiter, Mercury, Mars and Saturn are strong in order. Sun is the most powerful and Saturn the least.
The strength of planets are numerically calculated as follows.
There will not be any change for this values in any horoscope.
Drigbala is calculated as a result of the aspect to which each planet is subjected to by the other. The planet which is aspected is called Drishya Graham. The aspecting planet is called Dreshta Graham. The angle between the two is called Dhrushti Kendra.
The aspect of benefics give full Drigbala or strenghthen aspect of malefic take away the Drigbala.
It means that all planets view their 7th position. Saturn views 3rd and 10th have .Other planets have a quarter aspect to 3rd and 10th. Guru have aspect to 5th and 9th . Other planets have half aspect to 5th and 9th, Mars have aspect to 4th and 8th . Other planets have 75% aspect to 4th and 8th.
Sage Parashara has found out total numerical value of all strengths. He has identified individual optimal strength also. Yavanacharya has instructed optimum strength of 360 points for each. Jyotish is knowledge mixed with sadhana. Then we can identify the strength without numerical support. Albert Einstein was having mercury in debility. Einstein was one among the best knowledgable person. Seeing the debility, we cannot tell, mercury is powerless. Hence knowledge as well as sadhana is required to assess the strength of planets.
