As all of the belivers in astrology know transition of grahas is a major subject to be studied.Every Graha on certain rashies will give good and bad according to the rashie it occupies.Usually some astrologers consider the transition of Shani,Guru,Rahu,Shukra;they neglect other grahas transition.But surely we have to consider the transition of all grahas to come to the effects of transiton on certain person.Somebody calculates the transition from lagna but it has to be from Rashi though there is difference of opinion about it between astrologers I think it is from Chandras position that is rashi.
                                          I am sure that the predictor should be able to give remedies according to the textures and not according to his will.I have seen many giving remedies according to his will.or to do some gods of his choice but surely for each graha there is certain gods to be worshipped for eg.for Kuja thosha you have to worship Subrahamanya.He may be called in other names but the pooja should go to him.
                                             I seek peoples view in this subject.
