Ayana Bala

Ayana Bala

In this article, I will be writing about Ayana Balas which is part of the topic of Shadbhala. Shadbhala represents 6 fold strengths of a graha. The shadbhala is divided into 6 parts which is known as Stana Bala, Dig Bala, Kala Bala, Drik Bala, Naisargika bala, Chestabala.

Out of which Kalabala (Temporal Strength) can be further sub divided into catergories such as Ayana Bala, Varshadi Balas (Varsha, Masa Dina and Hora Balas), Divaratri Bala, Paksha Bala, Thribhaga Bala and Yuddha Bala.

Ayana Bala is based on the Kranti/Declination of grahas with respect to the Earth’s Celestial equator. Basically, its the angle between the celestial equator and the graha revolving on the ecliptic plane. Example for the Sun, the Kranti is 0 when it cuts the celestial equator at the vernal Equinox or Autumn Equinox during Mar 21 or Sep 21 respectively. Take note, for calculations of Kranti, we actually refer to the Sayana/Tropical Longitudes instead of the Niryana/Sidereal Longitudes.

To calculate Ayana Bala following steps are to be taken.

Grahas below with their longitudes. Take note for Ayana Bala, need to include Sayana Longitude (Nirayana Longitude + Ayanamsha value) So below table is based on Sayana longitudes.

Take note:

For Sun, its Ayana Bala = Chesta Bala

For Moon, its Paksha Bala = Chesta Bala

After calculating Sun’s Ayana Bala, the final value is to be multiplied by 2

Parashara Method:

1. Calculate nearest distance to Equinox. (0 deg Aries or 180 deg which is start of Libra of Zodiac Sign)

Eg: Sun 10 deg 22 Min Taurus. Therefore nearest distance to Equinox = 40 deg 22min.

Eg: Jupiter 06 deg 57 min Cancer Therefore nearest distance to equinox is 83 deg 38min.

At any point the degrees calculated will always be < 90 deg.

• There are 3 Khandas.

1^st 30 degrees/sign = 45

2^nd 30degrees/Sign = 33

3^rd 30 degrees/Sign = 12

Total adds up to 90 degrees.

Sun:

Say sun is on 40 Deg 22 Taurus. Therefore = 30 deg + 10 deg 22min

First 30 degrees Khandas = 45

Subsequent 10 deg 22min à (10 +22/60) ÷ 30 X 33 = 11.4033

Total Khandas = 56.4033

Jupiter:

Say Jupiter is on 83 deg 38 min Cancer.

(23 + 38/60) X 12 + 45 + 33 = 87.4533

Venus:

Say Venus is 26 deg 28min Piesces.  Nearest to equinox = 3 deg 32 min. (Within 1^st Khanda)

(3 +32/60) ÷ 30 X 45 = 5.30

• Rules for Specific planets

Moon and Saturn gets addition 90 if between Libra and Pisces. Otherwise, 90 – value

Sun, Mar, Jupiter Venus gets addition 90 if between Aries and Virgo. Otherwise, 90- value

Mecury always add 90.

• Final value ÷ 3 = Ayana Bala

Sun: 56.4033+ 90 (Since sun is between Aries and Vigo. At Taurus)

= 146.4033

Value ÷ 3 = Ayanabala = 48.80

For Sun Multiply by 2. = 97.6

Jup since its between Aries and Virgo. Apply rule 3.

 (87.4533 + 90 )  ÷ 3 = 59.15

Venus since it’s between Libra and Piesces apply rule 3;

90 – 5.30 = 84.7

84.7 ÷ 3 = 28.20

Method 2:

ayanabala = 30 * ( eps +- kranti ) / eps = 1.2793 * (eps +- kranti)

where eps is the obliquity of the ecliptic (23:27)

where eps is the obliquity of the ecliptic (23:27). The rules for addition/subtraction of the Kranti value are

Where Kranti = Declination provided in emphermeris

• Moon and Saturn: the value must be added for southern Kranti (From Libra to Piesces), deducted for northern Kranti.
• Sun, Mars, Jupiter and Venus: the value must be added for northern Kranti, deducted for southern Kranti.
• Mercury: the value must be added for northern and southern Kranti

Formula:

Ayana Bala = 30 X (23.45 +/- Kranti) ÷ 23.45

For Sun;

Ayanabala = 30 X (23.45 + 14 +56/60) ÷ 23.45 = 49.10

Muliply by 2 = 98.20

For Venus = 30 X ( 23.45 – (2 + 29/60)) ÷ 23.45 = 26.82

Note: Shri jyothi Star App uses this method.

Method 3: BV Raman Sir Method based on Bhava Balas and Graha Balas Book

Lets calculate for Chandra/Moon Graha.

Sayana Longitude = 332 deg 33min

Nearest Equinox = 0 deg Aries.

Distance to nearest equinox based on longitude = 27 deg 27min

BV Raman Formula: Bhuja Calculation

1st 15 deg elapsed (1st 15 deg) : 362min Arc

Subsequent 15 deg elapsed (2nd15 deg): 341 min Arc

Subsequent 15 deg elapsed (3rd15 deg): 299min Arc

Subsequent 15 deg elapsed(4th15 deg): 236 min Arc

Subsequent 15 deg elapsed (5th 15 deg): 150 min Arc

Subsequent 15 deg elapsed (6th 15 deg): 52 min Arc

Total = 362 + 341 + 299 + 236 + 150 + 52 = 1440 min = 24 deg which is the maximum kranti/Declineation of the ecliptic belt with the celestial equator. Take note that grahas revolve along the ecliptic belt.

Referring back to Moon Sayana longitude = 27 deg 27min

Therefore 1st 15 deg elapsed : 362min Arc

Subsequent 15 deg (2nd 15 deg) or part thereof

In this case balance is 12 deg 27min. (27 deg 27min – 15 deg)

(12 deg 27 min ÷ 15 deg) X 341min Arc = 283.03 min Arc

Total = 362 + 283.03 = 645.03 Arc Min = 10.75 deg = Kranti

To find Ayanabala Formula;

(24 deg +/- Kranti ) ÷ 48 X 60 = Ayanabala

Note: For Moon and Saturn: the value must be added for southern Kranti (From Libra to Piesces), deducted for northern Kranti.
Sun, Mars, Jupiter and Venus: the value must be added for northern Kranti, deducted for southern Kranti.
Mercury: the value must be added for northern and southern Kranti

Since Moon is in between Libra to Pieces at Southern Kranti, value to be added.

Ayanabala = (24 deg + 10.75) ÷ 48 X 60 = 43.44
