According to astrology, problems or difficulties in the life of every person come due to one or the other planet. Due to inauspicious and sinful planets in the horoscope, any person may have to face many problems and challenges in life. In Vedic astrology, Rahu is considered a sinful and shadow planet. If its position is not correct in the janam kundli, then the life of the person can be very difficult. Rahu and Ketu have 5th, 7th and 9th vision and it also affects the house in which it sits. Thus, if Rahu is in an inauspicious position in the horoscope, then it can directly affect 8 out of the 12 houses of the horoscope.
