There are 12 houses & 9 planets in the horoscope. The incision Rahu & Ketu positioned is at 1800. Rahu & Ketu are the only planets that move clockwise where the rest of the planets move anti-clockwise. When all other planets are sandwiched between Rahu and Ketu or say mouth and tail of the dragon, that conjunction is called as Kaal Sarp Dosha. There are different theories on the Kaal Sarp Dosha concept. As per some, Kaal Sarp Dosha is when it is in 2nd or 12th house of the horoscope; some consider the 5th and 11th house of the horoscope to declare Kaal Sarp Dosha where some also say that if planets are either side of Rahu & Ketu that result in Kaal Sarp Dosha. Some of these theories are based on myths and some on half-knowledge of the concept. In numerology, there is a life pattern grid or LPG. If you cross check the pattern, the missing number in LPG will represent the same area that is polluted in the house and the same planet troubling in the horoscope. You see, every planet represents a chakra & element. Balancing the LPG merely could balance all the planets in the horoscope. You can easily balance the planets using some simple remedies.
