Pitru Dosh Puja is a significant Hindu ritual performed to appease ancestors (Pitrus) and mitigate the negative effects of 'Pitru Dosh' in one's horoscope. Pitru Dosh is believed to arise when ancestors are displeased, have unfulfilled desires, or have not attained moksha, leading to various misfortunes for their descendants. This puja seeks their blessings and liberation. It is typically performed during Pitru Paksha (Shraddh Paksha), Amavasya tithis, or on specific auspicious days recommended by an astrologer. The puja involves key rituals such as Pind Daan (offering rice balls), Tarpan (offering water with sesame seeds), Havana, and feeding Brahmins. Mantras are chanted to invoke and appease the ancestors, seeking their forgiveness and blessings. Performing this puja helps remove obstacles, brings peace, prosperity, good health, progeny, and overall well-being to the family. It also aids in the spiritual liberation of the ancestors. The concept of ancestor worship and the importance of Shraddh Karma are deeply rooted in ancient Hindu scriptures like the Garuda Purana and Agni Purana, which describe the consequences of Pitru Dosh and the remedies for it. This puja helps solve problems like financial instability, marital discord, progeny issues, chronic illnesses, and a general lack of peace.
