Laghu Parasari says
" 41. If the lord of the Ascendant and that of the 10th mutually
exchange places, i.e., the Lord of the Ascendant is posited in the
10th and that of the 10th in the Ascendant then they form a Raja Yoga.
They signify position, power and reputation."
IN KAS WE STUDY THE SAME AS
10th house is D for 1st so it will give good name fame to person. 4th
house is 4th from 10th so like a helper or subordinate. 10th is that
of authority.
Now when the 2 exchange so 1st lord goes to 10th hosue means LoB has
gone into House D. Just check Parvez Musharaf's chart. Sco lagna and
Mars is in 10th house of the chart so its in House D.
Next, if 10th lord goes into 1st house so itself is becoming a
subordinate. Now as per KAS we go one step further and if the 1st
lord goes into 10th house with less than 4 bindus and lord of 10th
goes into 1st house with more than 4 bindus then the lord becomes very
powerful means such a person has very good personality and powerful
lagnesh. The power given will be that of 10th lord of the chart.
10th hosue is again special where malefic planets i.e. <>
good.
Now in some case Ju might become 10th and 1st lord so Pisces lagna and
Virgo lagna so 10th and 1st lords are same. So if Ju is in lagna then
such a person might get good name and reutation but at the same time
it will affect the 7th house 9th house and 5th house with malefic
aspect. Now if that is the case then the multiplication factor i.e
sign backing will also be high for Mercury it would be 1.6 and for Ju
it would be 1.4.
So one can study like that.
