[BPL: pari-varta-amsha]	If there be an exchange between a Lord of a Kendra and a Lord of a Kona, or, if a Lord of a Kendra is yuti with a Lord of a Kona in a Kendra, or in a Kona, or, if a Lord of a Kona is in a Kendra, or vice versa, or, if there happens to be a full Drishti between a Lord of a Kendra and a Lord of a Kona, [BPL: Mutual Reception] they cause a Yoga . One born in such a Yoga will become a king and be famous.
Dainya Parivartamsha Yoga Kahala Parivartamsha Yoga Maha Parivartamsha Yoga	Parivartamsha vs. Mutual-Aspect Case of Indira Gandhi: triple Parivartamsha gives extraordinary good and bad results Case of Marriage Violence: Exchange of Two Malefics gives Significantly Negative Results
	Parivartamsha yoga increases the power of the two bhava involved. It will also increase the power of the two graha involved. Increasing the power of these two bhava and these two graha may be helpful for the success of the nativity. If the bhava or the graha are inauspicious, the parivartamsha yoga may increase the negativity of results. If the graha involved are natural or temporal benefics; expect increase of ease and comfort in matters for which these graha are "karaka" or action-agents. For temporal benefics, effects of the exchanged two bhava are also smooth and relaxed. If the exchanged graha are are natural or temporal malefics; results may be emphatically more difficult than the graha might separately produce.
When Malefic graha = Benefic bhava-pati	If one or both of the graha are natural malefics that rule benefic houses(e.g., Yogakaraka Shani for Vrishabha or Thula lagna ) then results will be much increased in the style of that lagna. E.g., Shani is Yogakaraka for Thula lagna , but this fact does not make Shani an "easy results" graha! Thula natives have such a favorable prognosis for both cultural education (4) and individual intelligence (5) because Shani provides the lifetime discipline to shape, polish, and perfect the process. When Shani enters into a parivartamsha with another graha, Shani will add the empowerments of the exchange rashi to His birth-rashi empowerments. This means that He will become a "double-Shani" - doubly slow, doubly delay-causing, doubly persistent, and doubly-hard-working. Results of His efforts may be excellent, but the results are likely to take even longer, and require even more discipline, than if Shani did not enjoy the parivartan! Results depend entirely on the characteristics of the Graha which are exchanging their rashi.
Three varieties of parivartamsha yoga: good, bad, and great. Dainya Parivartamsha Yoga	If one of the Graha in the parivartamsha yoga rules a dushthamsha (bhava 6, 8, or 12), then the other graha will be damaged. According to K.S. Charak (p 637) : "This combination leads to a wicked nature, persistent trouble from opponents, and ill health." However, the dushthamsha lord will be strengthened by its interaction with the other non-dushthamsha partner.
Kahala Parivartamsha Yoga	If one of the exchange partners= lord of bhava-3, kahala yoga applies. Note: The non-L-3 partner cannot be also a dusthamsha lord. (If the non-L-3 partner would be a dusthamsha lord, the yoga would be Dainya, above.) The non-L-3 partner = lord of 1, 2, 4, 5, 7, 9, 10, or 11. The L-3 partner infuses the parivartamsha with courage, competitiveness, communications enthusiasm, and all of the powers of L-3. This yoga is considered beneficial with some limits. The limits on benefits is that L-3 gives mentalization, which can be superficial and repetitive as well as distracting from wisdom. Kahala yoga will energize the talking, scheming, competing mind to go out and get stuff done.
Maha Parivartamsha Yoga	When the lords of 1, 2, 4, 5, 7, 9, 10, or 11 get exchange of signs, Maha Yoga results. K.S. Charak (p 630) says, "This combination promises wealth, status, and physical enjoyments, plus beneficial influences from the houses involved."
An important difference: Parivartamsha vs. Mutual-Aspect.	The Yoga of Pari-varta-amsha ("re-versal of amounts") strengthens both planets even if they are both malefics - possibly increasing their evil capacity, but always dignifying both. Mutual Aspectby contrast does not normally dignify the two planets. Any two planets in opposition, 180 degrees apart, will provide mutual aspect to each other. If those two planets are friendly, the mutual aspect is a good thing, but then they will need to both rule favorable houses and occupy good signs in order to really help each other. The mutual aspect of Saturn and Mars which can occur when those two Graha occupy at 180 deg or 90/270 deg (4/10) angle to each other, is nearly always a disaster, causing intensely repressed anger which consumes most of the person's life force, eventually blocking the very accomplishments this person works so hard for. A Parivartamsha yoga of Shani and Kuja, no matter how much it might repress the animal vitality, will give full discipline from Shani and full productivity from Mangala. the native will definitely accomplish something in life despite a personal propensity to take the longer, harder road toward nearly every goal.
B. V. Raman: A Catechism of Astrology, 4th Ed., p. 28.	"Qu. 34: When Saturn falls in Mars' Sapta Vargas, and Mars in Saturn's Sapta Vargas, do they become strong?" "Ans: You cannot lay down any hard and fast rules in judging the strength or otherwise of planets when there is an exchange of vargas between two natural malefics. If it is a case of Parivarthana Yoga(interchange of places), this considerably strengthens it. In cases other than a parivarthana, due weight must be given to their lordship and similar factors. When Mars is a Yogakaraka and Saturn happens to be in Mars' vargas, then Saturn is automatically rendered strong. As to whether such strength expresses itself in good or bad respects depends on the horoscopic disposition of Saturn, though by virtue of Saturn's inherent malefic nature, a measure of evil is bound to predominate."
Q: During my current mahadasha, Budha occupies 12th from the mahadasha-pati Mangala, and it looks as if a pattern of retreat (12th) from the main business of the mahadasha (Kuja yogakaraka 4-9 and I am in the education industry) will cause a loss of energy for professional development. Even though Budha normally produces an upswing in my mental activities, it looks as if that mentalistic period of Budha will produce mainly interior thought and not too much result on the professionally visible level. But Budha enjoys (as you say) a parivartamsha with Guru, and Guru occupies the 10th from Mangala. That means "virtual" Budha should display some effects in that place, the 10th from Mangala. That means (I think) the obscurity and interiority of the Mangala-Budha 2-12 angle that normally would reduce the visibility of Budha won't be serious or maybe won't even happen due to the parivartamsha with Budha. Am I thinking correctly here? Can the "virtual" position acquired through parivartamsha cause Budha who is normally in a poor placement 12th from the mahadashapati to obtain a 10th effect?	A: In my experience, the bhukti of a graha which is engaged in parivartamsha yoga with another graha gives two different but simultaneous sets of results. The first set of results = what we would expect normally:  the outcome predicted by the distance of the graha from the mahadasha pati (in this case, Budha 12th from Guru) the social-material effects of 2 bhava from radical lagna as well as the psycho-emotional effects of 2 bhava from Chandra lagna. Then, to complicate matters, there is usually a second set of results measured from the 'virtual' position acquired via the parivartamsha. The second set of results may strongly evoke the 2 bhava ruled by the parivartamsha partner. For example, USA President GW Bush-43 ("junior") enjoys a parivartamsha of Budha-Karkata in lagna + Chandra-Kanya in bhava-3. When Bush entered the Budha-Budha swabhukti about 2/3 of the way through his 8-year term, he should have suffered obscurity caused by dissolution-of-identity L-12 Budha and overload of petty administrative tasks like meetings and schedules due to Budha's L-3 function. But that didn't happen. He attended fewer meetings than ever, and accomplished just as much == by delegating most of his decisions to his VP Cheney. His approval ratings did drop but he didn't disappear from view at all. The lagnesha Chandra in parivartamsha with Budha kept Bush's presence very strong. He continued to look fit and capable, bumbling no worse and no better than before. Observers had the sense that it was the same old George (lagnesha) not impaired in any way, and he wasn't looking as exhausted even as presidents typically look during their final years in office. Even with transiting Ketu moving over his Karkata lagna during the final 8 months of his term, the virtual Chandra-Karkata kept him looking vital (lagnesha) not burned out with mental tasks like we might expect from an inauspicious Budha period for the predominantly emotional Karkata lagna. Clearly a parivartamsha yoga can mitigate some of the worst effects of a difficult bhukti . However a parivartamsha is probably not a strong enough mitigant to reverse an entire unfortunate mahadasha. As soon as the subsequent Ketu period started, the protective effect of Chandra-Budha parivartamsha dissolved, and he left office in a state of surrender, with the worst approval ratings of any president in US history. He didn't re-emerge into public life for years after that.

Q:Hi Barbara: I am Computer Science professional specialized in AI. I was born in traditional Brahmin family and in childhood I learnt Jyotish as a legacy. Parivartan Yoga is kind of my research and interest and today I read your webpage on Exchange houses and I must say you did a really good job and put lots of ref. I want to know more about Kendra and Trikona exchange ( eg. exchange between --> 5th house and 10th house or 5th house and 9th house or 5th house and 7th house etc.) and any help from you would be highly appreciated.... Once again I must appreciate your effort in making and maintaining your wonderful website.	A: Namaste, Thanks very much for your compliments on www.barbarapijan.com Your research area is intriguing! You probably know more than I do about parivartamsha effects between kendra and trikona lords. Some possible examples of the kendra-trikona exchange might be: USA Pres-3, Thomas Jefferson (L-5/10 neechcha-bhanga Kuja with L-1 neechcha bhanga Chandra), PM India, Indira Gandhi (exchange of L-1 with L-7/8 And exchange of L-4/11 with L-6/9). = triple-parivartamsha! Involves lagnesha Chandra. USSR-dictator supreme leader Josef Stalin - L-3/6 with Yogakaraka L-4/5 (apparently parivartamsha applies; however, BT is uncertain) USA Sec State Hilary Clinton - exchange of Yogakaraka L-4+L-5 Shani with L-10 Chandra USA Pres-1, George Washington (BT uncertain) Other parivartamsha power-leaders: Richard Nixon = Shukra + Shani Fidel Castro = Budha + Chandra Napoleon Bonaparte = Chandra + Shani Vladimir Putin = Guru + Mangala G. H. W. Bush-41 ("Sr.") = Budha + Shukra G.W. Bush-43 = Budha + Chandra Please keep me apprised of your research! Fascinating subject! Sincerely, Barbara Pijan Lama, Jyotisha
Q: Hi Barbara, I am trying to learn bits and pieces of astrology and have been going through your website which is very resourceful. I have a question on parivartamsha yoga. In a known chart, from the lagna house there is parivartamsha between 2nd house and 10th house ....However if you look at it from Moon it is between 1st house and 9th house. Do I take it as parivartamsha only between houses 2 and 10? i.e should parivatana be considered only from Lagna? Thanks, B	A: Great question! Just about everything in a Jyotisha nativity needs to be examined from both the Chandra lagna AND the radix lagna. For unknown birth times, the Chandra lagna alone can be used, but this view alone is not nearly as detailed. In general, I read material effects, such as money in the bank, bodily health, houses and vehicles, from the radix lagna. I read psycho-emotional effects such as family relationships, spiritual progress, and positive or negative expectations, largely from the Chandra lagna. Since our normal life is governed by a combination of 5-senses material perception and 70+ senses of more subtle psycho-emotional perception (including thoughts) it is really beneficial to go through the material implications first, then read AGAIN for the emotional implications. For example, in marriage, there is a social, legal, and property relationship between the spouses which is best read from the radix lagna and navamsha lagna. But there is also an emotional interaction, which is very definitive of the marriage experience, and that level of reality can only be revealed by angles from Chandra. The short answer is, examine the parivartamsha yoga from both perspectives. Start with the material reading since that is simpler.Then consider the psycho-emotional perception. This double-assessment method potentially involves relationships between as many as eight separate houses. That is a lot to keep in mind at once! But humans have complex perceptions, and a yoga which benefits a person materially can harm one emotionally, or vice versa. Also remember that the parivartamsha effects are likely to manifest mainly during the Vimshottari periods of the exchanged graha. For predicting the effect of a parivartamsha graha during its Vimshottari Dasha period, consider lordship of each graha from radix lagna lordship of each graha from Chandra lagna ( lordship of each graha from the mahadasha pati. Best wishes for your success in Jyotisha studies, Sincerely, Barbara Pijan Lama, Jyotisha
Practical advice for reading a nativity with parivartamsha yoga	If one of the exchange graha = Lord of Lagna, the lagnesha function is much emphasized (for good or ill.) [Indira Gandhi ] It may be helpful to construct two different nativities in order to visualize the full effects of a parivartamsha nativity.
Case of Indira Gandhi: Triple Parivartamsha gives extraordinary good and bad results Indira Gandhi =  remarkable **Triple Parivartamsha Yoga involving Lagnesha Chandra** .
The basic kundali reveals a strong and disciplined personality. Yet in its original condition, before examination of the parivartamsha empowerment, the nativity appears rather fixated on work, attractive but not gifted, and perhaps -- with dark and tantric L-8 Shani in lagna - even hostile to social life. Guru	But there is much more to her story! Indira Gandhi was am extremely unusual woman. One of the fascinating features of her life was her surprising popularity with the people. She had a strange charisma which was absolutely unprecedented in her cultural era, when women had extremely limited permission to be involved in activities outside the home - let alone leading a huge nation through several cycles of political and economic crisis! Note that the TRIPLE parivartamsha effects place the lords of 1, 2, 4, 5, 6, 7, 8, 9, 10 and 11 all in swakshetra. The multiplicity of Parashari drishti caused by the triple parivartamsha is mind-boggling. rising Moon in any nativity gives doubled emotional sensitivity/reactivity Shani, Kuja, and Guru will each cast drishti to six houses (not their normal three each). Rahu amplifies BOTH benefics, Guru AND Shukra. Separation from spouse due to professional duties+ L-8 Shani in bhava-7 Politics always has an undertow of extreme physical danger (Kuja), and in the end politics is fatally violent. Psychological Control fixation in politics, Mangala-Vrischika-5 (add to the existing reptilian manipulate-and-control fixation from Azlesa lagna) Death by performance of duty+ L-8 Shani in leadership-Makara-kendra death by bullet, Mangala drishti to bhava-8 killed by countrymen+ L-8 Shani drishti to bhava-4 abundance of enemies - Guru+ Rahu, 6th from lagna AND 6th-from-Chandra regal political family, Ravi-2 Only Budha is not helped by the parivartamsha - yet even Budha, an adolescent, absorptive graha, get strengthened oratorical speech by proximity to a highly pro-active and even war-like swakshetra Kuja. Note the signification for violent death of children which comes with Vrischika Mangala in putra bhava.
triple parivartamsha nativities are rather complex and require much reflection to sort out the two sets of effects. It may be helpful to construct a second nativity which visually shows the exchanged graha in their "virtual" places. Creating a parivartamsha visual map will reveal a second narrative which underlies the primary ego social narrative and may provide clues to otherwise mysterious events or behaviors of the native .
Case of Marriage Violence: Exchange of Two Malefics gives Significantly Negative Results multi-millionaire male, whose life is (by self-report) wracked by suffering due to animosity of the spouse, anger in marriage, and a financially catastrophic divorce followed by self-inflicted financial losses. He claims no responsibility in the violence of his marriage, and yet his spouse calls him angry and abusive. Who is right? It is easy to see the commercial acumen of uchcha Mangala in bhava-3, the house of meetings, calendars, reports, and business administration. It is easy to see the complex, passion-driven work-identity (and potential for mental illness) of Shani + Rahu in lagna.	However, the it may not be easy to see the Rahu-amplified Kuja Dosha, disruption of home life, or severe depression without creating a new map representing the exchanged positions. In the special parivartamsha chart, the virulent Rahu-magnified L-6 Mangala is revealed to give extreme Kuja Dosha upon yuvati bhava. Clearly the native is responsible for his share of the reported marital violence. Shukra + Kuja gives the marital dilemma of never connecting satisfactorily with the spouse, and being unable to validate the spouse's material beauty or attractiveness due to the distancing behaviors of Ketu mixing with Shukra, karaka for wife. This dilemma is not part of the exchange but the dilemma is much negatively impact by the malefic exchange, since the effect of parivartamsha is to cast an evil Rahu-enflamed vindictive Vrischika Kuja drishti upon the marriage house. Results of this aggression will clearly harm the wife. Parivartamsha Kuja drishti also harms bhava-4, the home life, although not enflamed by Rahu, it is nevertheless a sign of fighting in the childhood home, which the native is likely to carry forward into adulthood. Finally Kuja's 8th drishti to bhava-8 suggests a violent death, quite likely through aggression. Shani cast drishti into bhava-3 the bhava of mental health, from the original Kundali, but a Shani drishti is not enough to overwhelm the positive dynamism of a captain-of-industry graha such as the birth-placed uchcha Kuja. However in the parivartamsha view, it is clear that Shani occupies the mental-health house with skeptical and depressive strength, a case of excess realism or worst-case thinking general with Shani/Makara/3. As this couple explained their narrative, delay in having children emerged as a major stress point. The male claimed that this delay was imposed entirely by the female. Is that true? Parivartamsha exposes Shani drishti to putra bhava, an indicator of delay for "practical reasons" (Shani) and often a depressed negativity (Shani) about children, emitting from virtual Shani in bhava-3. The third and tenth drishti of parivartamsha Shani is strong. Shani's virtual seventh drishti to bhava-9 would indicate trouble with the native 's father. While the native praised his father as a successful academic and virtuous parent, his contentious wife claimed that the native 's father was angry, depressed, and short-lived. Again it is not either-or, but both layers are true. The original chart shows uchcha Guru in bhava-9, surely the mark of a gifted professor. Yet the professor's personal life may well have been depressed and public record shows he was short-lived. Finally a block-and-delay Shani drishti to bhava-12: the native cannot remember his dreams. In the original Kundali, swakshetra L-12 Shukra should give luscious and sensual dreams albeit Ketu can devalue the guidance from spirit guides. (An ironic consequence of spiritual Ketu who devalues everything, associated with L-12 so Ketu promptly devalues one's dreams!). But the block against dream learning is very deep, the native has not remembered dreams for 60 years, and this is surely Shani. Shani/3 is nearly always a karaka for mental depression. the native enjoyed a very successful business life and built an enormous fortune, but he was never happy with his life. The L-6 which is already super-strong by uchcha status, as Kuja owns and aspects Ripu bhava, gains even additional malefic strength in the exchanged position: in lagna, swakshetra, with Rahu. There is tremendous animosity in his life, borderline criminal activity (highly activated L-6), and the spectacular wealth from a Laxmi yoga (swakshetra Shukra in 11th-from uchcha Guru-9) . Sadly the wealth was destroyed in mid-life by consequences of extreme angry aggression toward the wife. Mangala super-strengthened in bhava-1, a house of dissolution of stored wealth, 12th-from-dhana bhava. For wealth purposes, it may be said that the Amplified parivartamsha Kuja increases wealth in its role as L-1 casting identity-forming drishti with the major wealth karaka (swakshetra Kuja) and the uchcha wealth-expander Guru in bhava-9. the native projects the lion's share of his social identity into having millionaire status and lavishly entertaining his friends, especially women. Although the male native claims he is a victim of spousal aggression is appears that indeed the opposite is true. The natal Shani+ Rahu is a karaka for mental disturbance and a feeling of deep betrayal. However despite the ego conviction he holds that he is such a sober and hard-working man that he could not be the perpetrator of violence in marriage, parivartamsha shows that he is very much the agent of his own demise.
Q: Namaste Barbaraji, Hope you are doing great. I was reading about parivarthamsha yoga on your website. Its a fascinating subject to study and research. Does this yoga also apply when planets exchange Nakshatra instead of signs? For eg. sun in rohini and moon in krittika. Keep writing on your site. Great stuff!! Thanks.	A: Namaste, Great question! The answer, so far as I know, is that parivartamsha (parivartana) yoga applies only to sign-exchange between rashi lords. Thanks for your compliments on the website. I'm delighted to know that the sample materials available here are helping Jyotisha students to learn more of the vidya.div> Sincerely, Barbara Pijan Lama, Jyotisha -
