Vesi Yoga

A planet, not including the Moon, Rahu or Ketu, in the 2nd from the Sun.
"One born in Vesi Yoga will be even sighted, soft-spoken, firm in word, truthful, happy, bold, dear to his men, and popular among relations. Long-bodied, and indolent he will walk slowly, and have a bent body. He will be well balanced in his earning and spending and be endowed with some wealth. Malefics forming this yoga will give contrary effects."

Planets forming Vesi Yoga rise after the Sun; therefore, these planets are those that the native applies to that which they have in their lives, as compared to planets forming Vosi Yoga, which are used for purposes of initiation. Planets forming Vesi Yoga are not as activating and initializing as planets forming Vosi Yoga, rather they are what the native uses to benefit from and take advantage of that which they do have. The traits of these planets will become more noticeable as one gets to know the native. Since the Sun is a very activating and initializing planet, Vosi Yoga is a bit more powerful than Vesi Yoga. Classical texts, therefore, give Vesi Yoga slightly less influential results than they give Vosi Yoga.

Classical texts also give very different results to Vesi Yoga being formed by benefics vs. malefics:

"The person born in a Suvesi Yoga (Vesi Yoga formed by benefics) will be very handsome, amiable, happy, a store of merit, brave, triumphant over his foes, liberal, intelligent, intrepid, virtuous, eloquent, a king, delighting in scientific pursuits, and possessed of comfort, fame, wealth, and strength."

Benefics forming Vesi Yoga indicate that the native takes care of, uses, and benefits from the things in their life in a well to do fashion, which includes fairness, kindness, balance, gentleness, care, etc. As one gets to know the native, enjoyable, kind, fair and comforting qualities, in accordance with the nature of the benefic, will become evident in their nature. Benefics forming Vesi Yoga, which are debilitated in the rasi or navamsa, however, indicate troublesome character qualities that harm the native's capacity to take care of and benefit from the things they have in their life.

"The person born in an Asubhavesi Yoga (Vesi Yoga formed by malefics) is bereft of riches and comforts, very stupid, afflicted with lust, ugly faced, and will lose his splendor. Evil minded and wicked, he is fond of the bad and low, delights in murder, unjustly vilifies others, and may have to go into exile."

Malefics forming Vesi Yoga indicate that the native takes care of, benefits from and uses things in their life in a more stressful manner, which include pushing, taking things to the limit, putting things to hard use, etc. As one gets to know the native, tough, determined, opinionated, etc. qualities become evident in their nature. Malefics forming Vesi Yoga do indicate greater stress and difficulties with those things in the native's life, however, they also become more productive, so any other good yogas they are forming become more powerful and success producing.
Like Vosi Yoga, Saravali gives different results for the different planets that may be forming Vesi Yoga:

Mars"The native will resort to base means, but be helpful to others."

Mars forming Vesi Yoga by being in the 2nd from the Sun indicates natives that are logical, strong and willful with managing and taking care of the things in their lives. The people and things in their lives are utilized for purposes of achieving their objectives and they do not spare more time than necessary to relax with and maintain these things. These natives' strength, focus, strong-mindedness and strong opinions become more noticeable as one gets to know them.

Venus"The native will be timid, will face obstacles in his missions, will have pleasant movements, and be defeated."

Venus forming Vesi Yoga by being in the 2nd from the Sun indicates that the native very much enjoys the things they have in their life and that they recognize the importance of taking care of these things. Qualities of diplomacy, grace, charm, care, passion and enjoyment become more noticeable as one gets to know the native.

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.

Any planet, other than Rahu or Ketu, on an angle from the lagna.
Any planet on an angle serves to focus and direct the native; therefore, these planets can avert the troublesome effects of Kemadruma Yoga. Mentally, however, the native will be somewhat fickle and unfocused.

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.
