Dr. Shanker Adawal

1. Introduction
1.1 There are various ways in which one planet influences another or gets influenced in return. The simplest way is of being together in a house/ sign. When two or more planets join together in one house, they influence each other and modify each other’s results in a significant manner from what they would have produced singly. We have discussed such cases in Chapter No. 4 on “Conjunction of Planets”.

1.2 Another important method of one planet influencing the other is by aspect. The aspect may be mutual or singly. In mutual aspect, the two planets mutually transfer their characteristics to each other in proportion of their strength and thus modify each other’s results. A planet may aspect the other/ others singly or the planet may aspect others without getting aspected in return. This unilateral aspect transfers the characteristics of the aspecting planet to those it aspects. In this method the aspecting planet influence the aspected planet/ (s) without getting influenced itself.

1.3 There is also a third method by which two planets mutually influences each other; this is called Parivartan Yoga. The “Parivartan” is a Hindi word meaning exchange. This yoga takes place when two planets exchange their houses. By doing so, they tend to closely link two different houses, besides linking themselves. In this yoga, not only the planets share their characteristics, but the two concerned house also influence each other modifying each other’s characteristics. The planets undergoing exchange modify and gain some strength and behave as if they are located each in his own house.

1.4 The Parivartan yogas are an important feature of Vedic astrology. Any delineation of a horoscopic chart must include an identification of any Parivartan yoga present therein. Benefic yogas are produced if the exchange involves the lords of benefic houses. However, if the lords of adverse houses are involved, the results will also be adverse. Sometimes the exchange takes place between a benefic and a malefic lord; in such a case, the result will show the nature of the stronger of the two lords. The results in general are indicated by the nature, strength, and mutual friendship between the two lords. Any other planet conjunct/ associated or aspecting either of the two lords also modify the results.

1.5 Shri Mantreshwar, author of “Phaldeepika”, have divided the Parivartan yogas into three categories, depending on the nature of the houses involved.

i.) Maha-yogas: They involve exchange between benefic houses-1st, 2nd, 4th, 5th, 7th, 9th, 10th, and 11th lords. These are 28 in number. They promise wealth, health, status & physical enjoyments.

ii) Dainya Yogas: They involve exchange of Trika (6th, 8th, & 12th) lords with lords of other houses. They are 30 in number and generally produce adverse results regarding health, troubles from enemies & wicked nature.

iii) Khal Yogasa: These yogas are produced when 3rd lord exchanges place with lords of houses other than Trika houses. They are eight in number. They indicate fickle & wicked nature, fluctuating fortunes and temperament.

1.6 However the author is of the opinion that in addition to three group of exchange mentioned above, there are two more groups. One is exchange of lords of houses within Trika house, called Vipreet Raj Yoga. These are three in number. The other group is between lords of auspicious lords of houses (1st, 5th, 9th & 10th) on the one hand and the lords of houses 3rd, 6th, 8th, & 12th, on the other hand. These yogas are 16 in number and produce good results if the lords of auspicious houses are strong. It is proposed to discuss Maha yogas, Vipreet Rajyogas and yogas of auspicious yogas in this chapter. The other dainya and Khalyogas will be discussed in a separate chapter later.
