Kala Bala

Kala Bala is the temporal strength the planets, i.e. it is a collection of different sources of strength at the time of birth.

Kala Bala consists of 6 parts.

No. Kala Bala Type Description
1 Nathonatha Bala Diurnal/nocturnal strength
2 Paksha Bala Strength related to Lunar phase
3 Tribhaga Bala Related to portions of the day/night
4 Varsha-Masa-Dina-Hora Bala Astrological year (Varsha), month (Masa), day (Dina) and hour (Hora)
5 Yudhdha Bala Strength caused by planetary war
6 Ayana Bala Equinoctial strength. Some see Ayana Bala as a separate source of strength.

1. Nathonatha Bala

Nathonatha Bala relates to diurnal resp. nocturnal strength of the planets.

  • The Moon, Mars and Saturn are strong in the night and weak in the daytime.
  • The Sun, Jupiter and Venus are strong in the daytime, weak in the night.
  • Mercury has always maximum strength.


2. Paksha Bala

Paksha Bala is related to Lunar phase at the time of birth. Benefics get high Pakasha Bala near Full Moon, low Bala near New Moon. Reverse for malefics.


Paksha Bala in Virupas depends on the angle between Moon and Sun. The formula is

pakshabala = ( moon - sun ) / 3

The Bala must be deducted from 120 if the value exceeds 60.

This method yields a small value if birth takes place near New Moon (irrespective of placement before/after New Moon). Birth near Full Moon will result in high Paksha Bala (~60). Birth near Half Moon will have 30 Virupas.

This method is extended to all planets in Paksha Bala. Benefic planets (Jupiter, Venus) get Paksha Bala Virupas according to this method.

The method of calculation is reverse for malefics (Sun, Mars, Saturn) i. e. the value must be deducted from 60.

The Moon is benefic if birth takes place in the bright half of the month, i.e. birth is between New Moon and Full Moon. Reversely Moon is malefic for birth in the dark half of the month (between Full Moon and New Moon).

Mercury is regarded as malefic if conjunct with a malefic, benefic otherwise.

3. Tribhaga Bala

Tribhaga Bala is about portions of the day/night at the time of birth.

Each portion of the day resp. night has a lord as its ruler. The lord of the birth time will get full strength (60 Virupas). See table.

Day/Night Part Lord
Day 1 Mercury
Day 2 Sun
Day 3 Saturn
Night 1 Moon
Night 2 Venus
Night 3 Mars

Jupiter always gets 60 Virupas, i.e. each chart will have two planets with 60 Virupas Tribhaga Bala: the lord of birth time and Jupiter. Other planets will have nil Tribhaga Bala.

4. Varsha-Masa-Dina-Hora Bala

This Bala is about the astrological year, month, day and hour in which birth takes place.

Astrological fundaments and calculation of this Bala are described on the Hora page.

The strength of this Bala are

  • The lord of Varsha (year) gets 15 Virupas.
  • The lord of Masa (month) gets 30 Virupas.
  • The lord of Dina (day) gets 45 Virupas.
  • The lord of Hora (hour) gets 60 Virupas.

5. Yudhdha Bala

Yudhdha Bala is about planetary war. Planetary war takes place if 2 planets (Mars ... Saturn) are within one degree of each other.

The planet with the higher longitude is the winner. The difference of Kala Bala points aquired so far will be redistributed and must be added to the winner's amount and reduced from the loser's amount.
