Have you ever felt that for no apparent reason, you are constantly suffering . You are a pious, God-fearing person, you do not indulge in back-biting or wrong doing consciously, yet you or or your family members are always undergoing one or the other type of problems.
Astrology has a perfect explanation to this problem. It is due to the fact that the soul of our ancestors & departed forefathers does not get peace (Shanti). If knowingly or unknowingly our ancestors have done some mistakes, they are reflected in our Horoscope as Pitra Dosh or Pitra Rina and being their off springs we are destined to suffer from their bad effects.
Pitru Dosha is due to any of the following main reason, and there may be others.
Bad deeds ( bad karma ) of our ancestors in earlier life, knowingly or unknowingly, are embarrassing their souls.
Bad deeds ( bad karma ) of children, knowingly or unknowingly, are embarrassing the soul of ancestors
Lack of fulfillment of parental desires of our ancestors
A sudden and unnatural death of any relative ancestors in early age
If someone fails to remember and honor the ancestors properly
If certain wishes are remained attached with the soul of the ancestors, etc.
Pitru Dosha occurs if any ancestors up to the 7th generation on the fathers side and up to the 4th generation on the mothers side have expired at an early age or have had an unnatural death.
