Grahan Dosha Shanti Puja In Ancient astrological books, many works have been prohibited during the eclipse. The importent thing is that there is a solar or moon eclipse in your Janma Kundli as well. It is considered one of the worst yogas/Doshas of astrology.
If Sun and Rahu planets are together in the kundli then it is not considered good for the person. The conjunction of Sun and Rahu in the kundli is known as Grahan Dosha. Even if Rahu's vision on the house in which the Sun is located, then it is considered an Grahan dosh. Some astrologers also consider this yoga of Grahan dosha as Pitridosh in the kundli.
