Jaimini astrology defines the Chara Karakas. These Karakas depend on the planetary
positions in the horoscope. Most important is Atma Karaka (Karaka of self), see Parasara Hora Shastra
Out of these Karakas, Atma Karaka is the most important and has a prime say on the native,
just as the king is the most famous among the men of his country and is the head of all affairs
and is entitled to arrest and release men.
Eight Karakas are defined
2nd Karaka for self
Stree or Dara Karaka
Spouse and husband
In Chara Karaka calculation only the traversed longitude of the planets in their specific sign is considered.
So the planet with the highest longitude in his sign is Atma Karaka, the second Amatya Karaka etc.
Rahu is always considered in reverse manner: the order of Rahu depends upon the distance from the end of his sign
because Rahu is a regrograde planet.
Raman and Shastri use only the seven planets for Chara Karaka calculation. Dara Karaka is missing in this system.
Arudha Padas are one of the most important features in Jaimini astrology. Each
house of a chart has its Arudha Pada as a second point of influence.
Special Arudhas are
The Arudha of the 1st house is called Arudha Lagna.
The Arudha of the 12th house is Upapada Lagna.
Remark: Arudha Padas are defined for all Vargas.
Calculation of Arudha Padas
The rule for Arudha calculation: count so many signs from the lord of a sign
as the lord is away from the basic sign.
Example: Second house is Capricorn, Saturn is in Pisces. So the distance
from the underlying house (Cp) to Saturn is 3 signs. Count 3 signs from Pisces, so
Taurus will be the Arudha of the second house.
The Role of the Nodes
Rahu and Ketu play a special role in Jaimini astrology: they are co-lords of
Aquarius (Rahu) and Scorpio (Ketu).
So Rahu must be taken as lord of Aquarius if Rahu is stronger than Saturn.
Same for Ketu: Ketu is the lord of Scorpio if Ketu is stronger than Mars.
Parasara establishes that there are some exceptions from the above rule (fourth
Rule: if the lord of the house is in the 1st, 4th, 7th or 10th house,
4 houses must be deducted from the result.
Saturn is in the Ascendant in Capricorn. So the 1st house Arudha (or Arudha
Lagna) will not be Capricorn but Libra.
4th house Arudha for Cancer Ascendant and Venus in Aries: Cancer will be
the Arudha and not Libra.
Raman and Shastri do not apply the fourth house rule for Arudha calculation.
This rule can be configured in the configuration dialog
(vedic calculation tab) of Maitreya.
