Ju-mer own rashi kendras???????..
Virgo lagna in rashi chart and Ju is in leo (it means its 12th house) and Me is in aquarious (it means 6th house). You are right their aspect is good.
In rashi chart sat-mer exchanging their place. Retro Sat is in lagna(virgo).
In another rashi chart where Jup-ven exchanging their place. It is the exchange of 6th and 8th lord. Is it good for beneficial planet? (tauras ascendent)
All People laugh on me because I am Different but I laugh on them because They all are Same. This is my attitude. So "Think Different, Do Different and Be Different"!
