What is Pitra Dosh?
The word "pitra" means father. In Hindu vedic astrology Sun is the karak of father. And if in our kundli sun is present at the 9th house then due to the malefic effect of lord Rahu, a person may suffer from the Pitra Dosha. Because the 9th house of our kundli is always having the influence of lord Rahu. For these are 3 ways how a person will suffered from Pitra Doshas. 1st is, if you are not doing the required rituals of your ancestors properly. 2nd is, if the outside or unknown person is affected by your ancestors. 3rd is, if you are living the aged people of your family to fend for themselves then.
