what is grahan yog
What is Grahan Dosha? Whenever, Rahu or Ketu come together with the Sun or Moon then it results in Grahan Dosha or Grahan Yoga. Surya Grahan Dosh or Surya Grahan Yoga in Kundli (Birth Chart/Horoscope) is a malefic effect which arises when Rahu (Dragonâs head) sits with any planet in horoscope. For example, if Rahu is sitting with Moon then âRahu Moon or Chandra Grahan doshaâ is present. Likewise, if Rahu is sitting with Sun then âRahu Sun or Surya Grahan doshaâ is present and so on. In simple words, when Rahu forms negative formation in kundli or horoscope, it is called Grahan Dosh. There are several other cause for Grahan Dosha in a Kundli or Horoscope: 1  Rahu sits with Sun or Moon in any place/house in Kundli.  Ketu is sitting with Sun or Moon with the same rashi (zodiac sign).
