There are very many Raja yogas but it is essential to know as to when those Raja yogas would yield their assigned results. If the Raja yogas are loosely knit their results collapse at the prime of life, as was in the case of Napoleon Bonaparte who born in Libra lagna had Saturn, the Raja yogakaraka, conjoining with Mercury, the lord of the 12th house, in the 10th house but ten degrees apart, which afflicted Saturn and destroyed Raja yogas. N. Sundarajan states that the astrological factors required for success in politics are the strong lagna, the 5th house, the 10th house and the 4th house and their respective lords; a combination or association or aspect between these four factors (as was in the case of Jawaharlal Nehru), what is yoga and failure results only when they are weak and mutually unconnected but occupy the evil trika-bhavas or associate with the trika-lords in the Rasi-chart or Navamsa-chart (as was in the case of Morarji Desai). 3. Make a case for the mother being the real hero in the movie. Mercury aspected by the lord of the lagna and the lord of the 5th house can make a person a minister.

A powerful Raja yoga is caused if at the time of birth, Chandra lagna, Navamsa lagna and Drekkana lagna and the 7th house from these three are aspected by one planet (Sutra I.3.25). According to the Jaimini system of prognostication, when Janma Lagna, Hora Lagna and Ghatika Lagna are simultaneously aspected by a planet, the person becomes a ruler or one equal to him (Sutra I.3.24). Mercury aspected by the lord of the 9th house and occupying a kendra or a trikona from the lagna makes one a highly influential politician. A person becomes a leader, gains great political power and mass following if Mercury situated in a kendra or a trikona happens to be aspected by the lord of the 9th house, and the person born with Saturn situated in an Aquarius has four planets occupying their exaltation sign becomes a powerful ruler. A very powerful Raja yoga is caused if the Moon, Saturn and Jupiter are in the 10th, 11th and 1st respectively, Mercury and Mars in the 2nd and Venus joins the Sun situated in the 4th house in which event the Full Moon in the 10th will be aspected by Mars and be in mutual aspectual relationship with Venus and the Sun.

There are some Raja yogas described by texts which simply cannot occur, e.g. Varahamihira states that if exalted Mercury occupies lagna, Venus occupies the 10th, the Moon and Jupiter join in the 7th and Saturn and Mars occupy the 5th, the person becomes a ruler, this yoga cannot occur because Mercury cannot be in a kendra from Venus, certainly not 77 degrees apart for this yoga to arise, or if the Moon, Saturn and Jupiter are in the 10th, 11th and lagna respectively, Mercury and Mars in the 2nd and Venus and the Sun in the 4th, which event cannot take place because Mercury can never be in the 3rd house counted from the Sun. The lord of the 10th situated in the 6th house from the 10th, or either the lord of the 8th or the lord of the 11th associating with the Raja yoga formation or the Sun in its deep debilitation or Venus occupying the 5th house, the 12th or the 2nd house and the lord of the bhava of its occupation weak and afflicted or when all papagrahas occupy the kendras in their inimical or debilitation signs and are aspected by a benefic from a trikasthana ('cadent house'), are a few of the many factors that indicate Rajayogabhanga.

For instance, there will be Rajayogabhanga if there be along with Raja yoga-formation the simultaneous presence of a planet/planets (other than those involved in the Raja yoga-formation) in debilitation signs or debilitation navamsas, or of planets defeated in planetary war (Grahayuddha) or occupying inimical signs or in bhava-sandhi or planets that are weak, combust or retrograde, or if any one of those planets happens to be in conjunction with Rahu or with the lord of the 6th or the 8th or the 12th, or with the lord of a kendra, a functional malefic.(Source: Uttara Kalamrita) Also, if the Lagna (Ascendant) is neither in vargottama nor aspected by a benefic, and if Trishanku Nakshatra is rising and Saturn is in lagna then too Raja yogas will get nullified.(Source: Saravali) In any Raja yoga formation if the lord of the 10th house happens to occupy the 6th house counted from the 10th the impact of that yoga wiil be slight or for a short period only, there will be no permanent yoga.
