In your birth chart Saturn is indeed in the 8th sign in the rasi chart. But in the bhava chart, he moves to the 7th. Saturn is a good planet for you – in fact a yogakaraka. And 8th house does not always indicate bad things. Saturn in the 8th gives you a long life. He can give sudden success and wealth as well. There is a big angular difference between Saturn and Rahu. They are in different nakshatras as well. So don’t focus your energies on being fearful of Saturn.
Do things the right way. Don’t shirk work or take short cuts, whatever be the provocation. It can give you breaks in profession, but all breaks may not be bad.
