Causes of Pitri Dosha
Pitri dosha is traced to the ninth house and the Sun, and the ninth house is dharma, including the bond with the father and the ancestors. A weak Moon is a different dosha and should not be folded into this one.

Cause is a chart condition
The ninth house is dharma. The Sun stands for the father. Popular practice names Pitri dosha when Saturn, Rahu, or Ketu pressures the ninth or the Sun. The exact combination is not identical in every manual, so the cause is that family of placements, not a story about a forgotten ritual you cannot verify. The sixth house is conflict and debt. Ordinary loans are not this dosha. The eighth is longevity. A death in the family is not, by itself, the cause. The lagna, the first house of the self, shows whether the native carries the ninth or is crushed by it.
Effects stay inside the ninth
The effect, when the condition is real and the period is open, is strain in dharma: trouble with a father or a teacher, a duty that will not resolve, a belief that keeps breaking. It is not a catalogue of diseases, and no medical effect is stated here. It is not a block on the seventh house of marriage unless the seventh lord is also involved. Navamsa can soften or repeat the ninth. Vimshottari of the Sun lasts 6 years. The ninth lord's period may be longer. Outside those clocks the natal condition can be quiet.
Remedies are duties
Remember the father accurately. Keep the ancestral offerings your own family already practices. Give food on those days. Clean the second house of speech, which is where elders are often harmed with sentences. Do not curse a relative, living or dead, and do not buy a rite that claims to bind an ancestor. If Jupiter aspects the ninth and the lord is strong, you may not have the dosha at all. Lahiri positions decide. A remedy for a dosha that is not present is anxiety with incense.
Frequently asked questions
What causes Pitri dosha in the chart?
Pressure on the ninth house of dharma or on the Sun, often from Saturn, Rahu, or Ketu. Manuals differ on the exact combination. Life events alone do not prove it.
What does it affect?
Dharma, father, teacher, duty. It is not a disease list and not automatically a marriage block. The seventh is a separate house.
What remedy is acceptable?
Filial remembrance, the family's own offerings, and cleaner speech. Nothing here targets a person. The Sun mahadasha lasts 6 years if timing is the question.
