Pitru means ancestors. Pitru dosha is the traditional idea that unresolved obligations to one's forefathers, rites left undone or past wrongs in the family line, can show up as obstacles for their descendants: delays in marriage or children, family discord, or repeated setbacks. It is a matter of faith and family tradition as much as of astrology, and is best approached calmly.
Chart factors astrologers associate with it
There is no single classical definition. Astrologers commonly look for:
- The Sun, the karaka of the father and lineage, joined or closely aspected by Rahu, Ketu or Saturn;
- the 9th house (father, ancestors, dharma) or its lord afflicted by Rahu, Ketu or Saturn;
- Rahu in the 9th house, or the 9th lord in the 6th, 8th or 12th with affliction;
- an afflicted 5th house (children, past merit), which tradition links with ancestral blessings.
Brihat Parashara Hora Shastra discusses curses affecting progeny in its chapters on children; the broader modern idea of Pitru dosha has grown from such passages and from family tradition.
Reading it sensibly
- Most charts have some of these factors. Rahu or Saturn near the Sun or the 9th house is common.
- Look at the whole chart. A strong 9th lord, Jupiter's aspect, or good dashas outweigh a single affliction.
- Be wary of fear-based selling. Expensive rituals should never be bought in panic.
Traditional remedies
- Pitru Paksha: the sixteen lunar days in the dark half of Bhadrapada (around September–October), set aside for honouring ancestors with shraddha.
- Tarpan (offering water with sesame) on Amavasya, especially Mahalaya Amavasya.
- Feeding Brahmins, the poor, crows and cows in the ancestors' names.
- Pilgrimage to places such as Gaya, Varanasi or Rameswaram for shraddha.
- Caring for living elders, the simplest remedy of all.
See Amavasya and Purnima for the monthly days used for ancestral rites. If a family concern weighs on you, a private consultation can read it in the context of the whole chart.
