Astrology Yogas

Bheri "kettle drum" Yoga
Venus and the lagna lord in angles to Jupiter, and the 9th lord strong.
"One is lordly, of good birth, a king, famous, eminently heroic, long-lived, of great experience in the affairs of the world, exempt from diseases and danger, possessed of much wealth, lands, sons and wives, and enjoying much happiness on account of their virtuous lives."
    This yoga offers the protection, character, and merit of Jupiter, and the worldly wisdom and enjoyment of Venus, supported by the fortune and dharma of the 9th lord.

Gaja Kesari "elephant lion" Yoga
1.    Jupiter in an angle from the Moon, and joined or aspected by a benefic, avoiding at the same time debilitation, inimical rasi, or combustion.
2.    Jupiter in an angle from the Moon.
"One will be splendorous, wealthy, long-lived, energetic, renowned, intelligent, endowed with many laudable virtues, pleasing the king, and having great money and grains. One will destroy, like a lion, all his enemies and conquer everything by his own valor."

    This is a well-known yoga that indicates intelligence, a happy attitude, and protection from adversity. It is particularly noted for wealth, and the houses involved will indicate sources of wealth. The first version, requiring Jupiter to be under benefic influence and not in a bad dignity or combust, is much more significant and effective. In this case it is Jupiter that is the significant planet in the yoga and the planet that will give the greater rise, success and wealth. The version that is formed simply by Jupiter's placement on an angle from the Moon is very common, occurring in one out of three horoscopes and is not very significant by itself, though if Jupiter and/or the Moon are involved in other yogas their formation of this simple Gaja Kesari Yoga will be a contributing factor for success and wealth.

Kahala "large drum" Yoga
The 4th lord and Jupiter in mutual angles, while the lagna lord is strong.
"One will be learned, of high moral training, energetic, adventurous, handsome, charming, well-balanced, obedient, having the best pleasures of life, lording over a few villages, and endowed with a complete army consisting of chariots, elephants, horses, and infantry."

    This good placement of the 4th lord in reference to Jupiter in the first version of this yoga indicates a happy native who feels that their life has purpose and who is, therefore, energetic and inspired. .

Kahala "large drum" Yoga
The lords of the 4th and the 9th in angles to each other, and the lagna lord strong.
"One will be learned, of high moral training, energetic, adventurous, handsome, charming, well-balanced, obedient, having the best pleasures of life, lording over a few villages, and endowed with a complete army consisting of chariots, elephants, horses, and infantry."

    This good placement of the 4th lord in reference to the 9th lord in the first version of this yoga indicates a happy native who feels that their life has purpose and who is, therefore, energetic and inspired.

Sankha "conch shell" Yoga
The 5th and 6th lords in mutual angles, and the lagna lord strong.
"One will be endowed with wealth, spouse, sons, and land. Having a life of enjoyment, one is also kindly disposed, compassionate, propitious, intelligent, meritorious, beneficent, and long-lived. One has knowledge of the sacred scriptures, is well conducted, and may live one year after the tale of eighty is completed. One has the authority to discipline or to punish."

    The Sankha Yoga formed by the first condition of the 5th and 6th lords in mutual angles supports self-employment or authority and rids the native of performing service. It also indicates a healer or doctor very capable of removing disease in the event that other factors in the horoscope indicate a healer.

Chandra "Moon" Yoga
The 10th lord in an angle, trine, or 2nd from the Moon.
"One becomes a king having special kinds of gems, diamonds and jewels."

    This common yoga indicates the importance of the relationship between one's mind and one's karmas. The 10th lord in an angle, trine, or in the 2nd from the Moon indicates harmony between one's mind and karmas. The native's actions will correspond with their mentality and they will be more comfortable with their works. On the other hand, the 10th lord not in these places indicates a lack of harmony, or conflict in the case of the 10th lord being in the 6th or 8th from the Moon, between one's mind and karmas. In this case the natives actions don't necessarily correspond to their mentality, and they don't feel as comfortable with their works. This yoga, by itself, is not a very powerful success producer but it does exert an important influence upon the native's relationship to not only their career, but to all the deeds they are required to perform.

Budha Aditya "Mercury/Sun" Yoga
Mercury conjunct the Sun.
"One is highly intelligent, skillful, of good reputation, personal respect and surrounded by comforts and happiness."

    This is a simple and common yet important yoga. The house that the Sun and Mercury both fall in will be an area where the native will make progress through their skill, intelligence, productivity, and practicality. If Mercury is combust this yoga will still indicate skill, intelligence, etc., however, the results of a combust planet's avastha, Kopa- angry, will cause frustration to the house these planets fall in as well as to the houses that Mercury rules, so the happiness will be marred.

DASA INDEPENDENT FOUNDATION YOGAS
Kemadruma Yoga
If Anapha, Sunapha or Durudhara Yogas are not present, Kemadruma Yoga is formed.
"One born in Kemadruma Yoga, though born in a princely race, becomes obscure, inimically disposed, miserable, reproached; and bereft of intelligence and learning. Given to base ways and wickedly inclined, one falls from his religion. One is reduced to penury and perils, drudging as a menial and wandering, as well as being deprived of livelihood, wife, children, residence, robes, friends, food and drink. The native will suffer extreme difficulties, sickness and filthiness."

    Kemadruma Yogas are amongst the worse yogas that ruin a horoscope, making it difficult for the native to actualize anything of benefit in their lives. Amongst Kemadruma Yogas this one is perhaps the worst and one of the two of greatest importance. The Moon is a very fickle and unsteady planet that rules the mind. It is important that a planet besides the Sun, Rahu or Ketu is in the 2nd or 12th from the Moon in order to lend some firmness, stability and direction to the mind, which is necessary in order for the native to succeed with any vision that they may have. Failing this, the mind remains unanchored and becomes a source of trouble. Fortunately there are several factors that cancel this terrible form of Kemadruma Yoga, which are being given in order of significance:

A planet, other than the Sun, Rahu or Ketu in an angle (including the 1st) from the Moon.
    This is the most significant Kemadruma Yoga cancellation. The planet on an angle from the Moon serves to stabilize and focus the mind. A planet in the 4th or 10th from the Moon does this particularly and is the next best thing to having a planet in the 2nd or 12th. In fact similar effects as Anapha, Sunapha and Durudhara Yogas are said to occur if the 4th and 10th houses from the Moon are occupied by any of Mars, Mercury, Jupiter, Venus or Saturn, and some astrologers actually consider these yogas to be formed by planets in the 4th and 10th from the Moon, though they are not considered authoritative. These planets in the 4th and 10th house from the Moon will influence the native less than when in the 2nd and 12th from the Moon, but if there are none of these planets in the 2nd or 12th from the Moon, then any of these planets in the 4th or 10th become very significant and important.
    In all cases when there is Kemadruma Yoga and its cancellation, it is not as beneficial as having one of Anapha, Sunapha or Durudhara Yoga. When one of these yogas is present the native maintains poise and equilibrium when confronted by new experiences, the Lunar Yoga forming planets in the 2nd and 12th from the Moon ground and stabilize the native. When there are no planets in the 2nd and 12th from the Moon the native has nothing solid to react upon when confronted by new experiences and it takes them a moment to get centered. In this case, if the resulting Kemadruma Yoga is cancelled, the planets canceling the Kemadruma Yoga are what the native relies upon in order to catch their balance. The norm and average is for Anapha, Sunapha or Durudhara Yoga not to be present, but for the resulting Kemadruma Yoga to be cancelled. When Anapha, Sunapha or Durudhara Yogas are found, consider them to be a benefit to the horoscope.

A planet, other than the Sun, Rahu or Ketu, in the 2nd or 12th rasi from the rasi of the Moon's navamsa.
    As an example, if the Moon is in the navamsa of Aries, one of Mars, Mercury, Jupiter, Venus or Saturn in Pisces or Taurus in the Rasi would cancel Kemadruma Yoga. Some sources actually consider the planets in the 2nd and 12th rasi from the Moon's navamsa to form Anapha, Sunapha and Durudhara Yogas. These planets will, however, give somewhat lesser Lunar Yoga effects than planets that are actually placed in the 2nd and 12th from the Moon.

When Anapha, Sunapha or Durudhara Yogas are found, consider them to be a benefit to the horoscope.

The Moon being full.
    In the event that the Moon is bright (when it is a benefic) the serious negativity of Kemadruma Yoga are avoided. The mind will be fickle and less focused than ideal, but it will not be so full of unfulfilled longings that it will completely disrupt life or not contribute to any growth.

Adhama "worst" Yoga
The Moon in an angle (1st, 4th, 7th or 10th) from the Sun.
The native's wealth, intelligence, knowledge, and skill shall be little.

    These are important yogas that must be used correctly or else they will be misleading. A casual observation of only a few horoscopes will reveal that there are wealthy, intelligent, and knowledgeable personages with the Moon in an angle from the Sun, and those of lesser abilities and wealth born with the Moon in an apoklima from the Sun. These yogas obviously, therefore, do not impose a restriction upon the native's wealth or intelligence. The Moon gives growth of all things and the light of the Moon is dependent upon the Sun, therefore, the growth and realization of any productive yoga, whether one that grants success, wealth, marriage, children, or anything else, is dependent upon the Moon's placement from the Sun, which indicates the level of preparedness with which the native meets the fructification of a productive yoga. These three yogas are not meant to indicate the full measure of the native's wealth, intelligence and skill, but only to indicate the measure of wealth, intelligence and skill the native has upon the initiation of a productive yoga with which to bring the results of the yoga to fruition.
    When Adhama Yoga (worst yoga) is present, the Moon is in an angle from the Sun. The angles represent initiation and the beginning of an activity. Therefore, in horoscopes with the Moon in an angle from the Sun, the yogas, etc. are being freshly initiated, the result being the native's is not prepared for what is to transpire. Practically, the native does not have the wealth, education or skill, at the time of the initiation of a good yoga, required to smoothly bring the results of the yoga to fruition. The result is difficulty and stress as they prepare themselves and their life for the good effects of the yoga to come.

Following are a few important yogas from the book Core Yogas that Kala is not smart enough to find yet, but which are well worth checking for manually:
Kalpadruma "tree of plenty" Yoga
The lagna lord, its dispositor, the dispositor of that, and the navamsa lord of the last must be in an angle, trine, own rasi or exaltation rasi.
"One will be a pious, strong, and merciful king endowed with all kinds of wealth, and fond of war."

    This yoga further illustrates the concept of dispositors, including the navamsa dispositor. The more times a dispositor of a dispositor is well placed, the more auspicious the original planet in question becomes. Kalpadruma yoga, like Parijatha Yoga, helps the native to fulfill every desire.

Parijatha "celestial coral tree" Yoga
The dispositor of the lord of the lagna lord, and the navamsa lord of that dispositor, must be in an angle, trine, own rasi or exaltation rasi.
"One will be a sovereign attentive to their duty and engagements, of compassionate disposition, destined to be happy in the middle and latter portion of life, respected and obeyed by other kings, fond of war, and possessing elephants and horses."

    The Parijatha is a celestial tree that has the power to grant wishes. This yoga, therefore, helps the native to fulfill every desire. This yoga emphasizes the importance of the navamsa dispositor of a planet, which is just as important as its rasi dispositor.
