Pitra Dosh Nivaran Puja is a special ritual performed to alleviate the negative effects of Pitra Dosh, which is believed to occur due to the unsettled souls of ancestors. This dosh can bring various obstacles and difficulties in a person's life, affecting health, wealth, and overall well-being. The puja is often conducted by a knowledgeable pandit who chants mantras and performs the necessary rites to honour and satisfy the ancestors.
