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.
When Rahu will be in Sagittarius, ketu will be in Gemini or in 3rd house. The native gets over excited from time to time. This is the worst placement for one to be a media reporter. The native relies more on logic then intuition and is proven wrong many times. He misses the larger perspective completely. The native usually is of flickering mentality and does not stick to one thing for long. The native basically does not have belief in his beliefs and this makes his standing dubious in front of others.
