Combinations of Rajayogas and Dhanayogas occurring in trik houses acquire a new meaning in today’s day and age. If we apply the same principle as written in shastras we can go wrong. Therefore, as said by Sh. K.N Rao apply principles from classics liberally and not literally.
Lets us understand this with an example:
Chart of a businessman born in 1964
Notice the following yogas:
Sasha Yoga: Saturn in own house(mooltrikona) in 10th
Malavya Yoga: Venus in own house in lagna as lagna lord. Notice the degrees of Venus and ascendant
He has concentration of planets in the 12th House: Mer(R), Jupiter and exalted Sun
This concentration of planets in the 12th house forms rajayoga and multiple dhanayogas aspected by a yogakaraka Saturn which is in turn in its mooltrikona sign. Also, notice the exchange of 11th and 12th lords. This makes the 12th house very powerful.
Let us look at the dasha pattern along with navamsa:
Career: Second half of Dasha of Rahu was uneventful for him as he did a lot of hardwork but had very little to show for it. He was doing a business related to educational materials.
Jupiter Mahadasha: Post 2000 as he was in the beginning of the dasha of Jupiter he started to get contracts for exports. Notice this Jupiter participating in all the dhanayogas and rajayogas and in the 12th house of exports.
For Taurus lagna, Jupiter is a malefic as it owns the eighth and the eleventh houses and placed in the twelfth. Throughout the Jupiter dasha he got one contract after another and built a high sustaining business around it and has earned in millions.
The blemish of Jupiter came to him as a health issue in Jupiter Venus period which was very serious for a couple of years, but he overcame that and now is in good health. Therefore, Jupiter did give its effects as the eighth lord and Venus AD is the sixth lord as well.
He continues to do better in his Saturn Mahadasha which is also the yogakaraka.
This is an example of Dhanayogas and Rajayogas in the 12th house giving extremely positive results for the native.
