Sage Kalidas in Classic Uttarkalmitra -Kanda 4 sloka 22 has mentioned that “if the lords of the houses 6, 8 and 12 occupy either jointly or individually the houses 6, 8 and 12 or if they are in any manner connected with the houses 6 or 8 or 12 if they mutually interchange their places, provided these planets do not have any connection with other planets not owning 6 or 8 or 12, then the person will be a king and he will command much wealth. He will establish a good name and enjoy his life.”
The term vipareeta imply reversal of something. Hence, these rajayogas are formed due to downfall of someone, based on which the native's fortune is reversed. The downfall can be of an enemy or a someone near to the native, however the combinations are somewhat different for both circumstances.
This is akin to a boomrang coming back at you if not caught in time it can either hit you or fall down harmlessly ,
Vipreet Raj Yoga is created. For instance, if the lord of the eighth house is in twelfth house or sixth house, and lord of the sixth house is in eighth house, lord of the twelfth house is in sixth or eighth house, and the lord of the trine houses are in conjunction or have a aspect on each other, then the person will be very rich and happy. According to the Vedic Astrology scriptures, if a planet which gives malefic results is placed in a malefic house, then its malefic influence is cancelled.
:-- If the two or more lords of malefic houses (Dusthanas), namely, 3rd, 6th, 8th or 12th houses stay in conjunction in 6th, 8th or 12th houses or have exchange yoga (stay in each other’s house), the person enjoys royal comforts and affluence in life during the main-periods of those planets.. No malefics should be related to these planets, which ruin the raja-yogam. Also other planets should not conjunct with these 2 or 3 planets; then the yogam is ruined. So It implies the collection of power or gains coming together due to another's ( or ones own) down fall or death of another.
1. The direct benefit from the loss or misfortune of another. Many call out the down-fall of an enemy due the malefic house (dusthanana) influence, yet this is not always the case and therefore;
2. The rise or benefit to the native based upon the downfall of a friend or ally.
Generally a key role is played by Saturn, as Sani is the natural karaka (significator) of malefic houses (dusthanas).
Saturn . It is evident from the above that the giver of Vipareeta Rajyoga is Saturn, more so since he is the natural significator of the Dusthana. Thus, VRY can also be caused if Saturn becomes a Yogakaraka (for Taurus & Libra Lagna) and is placed in a Dusthana in debility/weak. However, it is important that other planets should not conjoin this, else their significations could be destroyed.
