The Pitru dosh word is a combination of two words "Pitru" which means forefather and "Dosh" means imbalance in person's Kundali. Pitru dosh occurs when Rahu and Ketu are both misplaced in a person's birth chart, and sometimes this dosh occurs when the soul of the ancestors is not satisfied. To get rid of this dosh one must perform rituals. It is a person's duty to respect and make donations to satisfy their ancestors.
