Rahu is probably the most dreaded planet of all and the irony is that it is not even a planet but a mere shadow. It is associated with many things and people interpret its results variedly. No two astrologers will be giving the same prediction usually for the same placement of Rahu or Ketu. I am going to talk about the placement of rahu and ketu with respect to the horoscope of time i.e. kaalpurusha's horoscope where Aries will fall in the first sign, Taurus in second and so on. One can correlate with his natal chart the effects of these two in his horoscope in houses and signs.
Rahu in Taurus will make ketu in Scorpio. The speech of the native can be venomous. He could be very selfish, cunning and very negative in thinking. The person invites troubles for himself and then blames others for the same. One is always in the panic mode even for small things. The native is ever confused and in process confuses others. One may be very helpful too and may disrupt the peace of life he is going through and invite trouble in the process. The person is never satisfied and always complaining about life and people. He will like foreign lands and people. He may not like his relatives and near ones.
