The yoga is considered one of the bad yogas which can create trouble to the native if the influence is strong. If Sun or Moon is placed with either Rahu or Ketu in one’s horoscope, a Grahan Yogais said to be formed which is not good. The native has to face struggle in various spheres. The literal meaning of the Grahan is to eat up completely. The Rahu or Ketu in the Horoscope can make your life hell.
Grahan Yoga Effects:
The astrology science says there are 12 houses in horoscope and all the planet among navagraha are placed in one or 12 houses. Rahu and Ketu moves in retrograde motion and they stay in one Zodiac sign for around 18 months. So, it may possible that the Yoga is made in your Rashi.
Remember, the combination of benefic Sun with Benefic Rahu and malefic Sun with benefic Rahu don’t cause the Yoga. But if the both are malefic or benefic Sun with malefic Rahu, the combination can form the Grahan Yoga.
