Sonu ji,
Are you quite sure that Ketu is the karak for mistakes? I knew Rahu to be the karak for mistakes - by being too clever by half.
I don't know how to use Narayana Dasha. So what kind of mistakes do you foresee? Work related, marriage or affair related? (10th being the 4th fr 7th) And how long does this Cancer-Cancer last?
Btw, I was a bit surprised that you made such a brilliant deduction but you missed the connection to politics. I was heavily into politics, taking a bit of a sabbatical for now. But will resume again.
Thanks a ton.
