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.
With Rahu in Capricorn, Ketu will be in Cancer in 4th house.
The native suffers due to emotional issues rather than practical ones. The native has a fear of rejection and it usually results in opportunities being missed by him. He is usually depending on others for fulfillment of his tasks. His past keeps coming to his mind and childhood days matter too much to him. The native does not come to the "take charge" position usually. The native is not able to set a balance between his emotionality and work tasks and this usually hinders his growth.
