Our ancestors are known as Pitra in Hindi. Pitra are those people who died unnatural death or our ancestors who did not get salvation and create problems and want to get relief from Pitra Yoni..Pitras are our own ancestors, they are considered to be more important to a person than any other devata, as they are having blood relationship with their successors.As this body of ours has come into existence because of our ancestors, pitra dosha nivaran is considered to be a very important duty of a person. If the pitras are satisfied and happy with your shraddha they can bring joy and clear your path to success in all spheres. Success is almost not possible if one has pitra dosh in ones life. As our pitra are ethereal beings Pitra Dosh is not a curse of the Ancestors for sure but the ethereal debt which has to be paid back that is the reason we do shraddha for full fifteen days to appease our ancestors. It is the duty of a learned astrologer see whether the native has pitra dosha or not . In the horoscope the pitra dosha can be judged from the afflictions to the 10th lord and the 10th house from the lagna(ascendant) and the Moon. If simultaneously Sun is also afflicted by Saturn, Rahu or Ketu, the karmic issues get further enhanced. If, simultaneously, Moon also gets afflicted, the problem becomes more complicated.Pitra dosha can cause many problems like:-a) Childlessness b) Repeated miscarriages c) Family disputes d) Health issues in the family e) Obstacles in career and education without any apparent reason f) Inability to get married g) Addictions h) Birth of mentally challenged children i) Demise of children at young age. Prescribed methods for dealing with the issues related to forefathers are available in our religion. The successors should take steps prescribed in religious texts for the mukti of the souls of ancestors.Few of them are as follows:(1)Your pitra will get satisfied if you will do Pinddaan, worship and Tarpana on the date of death of pitra with sesame, couch grass, flowers, raw rice and Ganga water or pure water.( 2) People who dont know the date of death of their pitra can perform all these activities for pacification of their pitra on the day of Amavasya. (3) Worship of the Peepal tree also removes this dosha. Offering Kheer to his pitra on the day of Somvati Amavasya..(4) Give respect your parents and other senior members of family and take their blessings to strengthen the position of Sun.(5) Stand on a mat and look at the Sun during Sunrise, chant Gayatri Mantra to strengthen the position of Sun in your horoscope.(6) Donating Ruby Gomed are also very beneficial in warding of this problem.
