Check for Pitra Dosha (ancestral debt) in your Kundli. Identifies the degree of affliction, causes, effects on life, and Vedic remedies.

Pitra Dosha (also spelled Pitru Dosha) is not a curse someone put on you — it is the chart’s way of marking unfinished ancestral karma, a debt (rina) carried down the paternal line. Classical Jyotish reads it from two places at once: the 9th house (father, ancestors, dharma, fortune) and the Sun (Surya, the karaka of father and lineage). When both are shadowed — usually by Rahu or Ketu, sometimes by an afflicted Saturn — the tradition says the ancestors’ business is still open, and part of your life’s work is to close it with remembrance.

We compute your Sun, your 9th house and its lord, and the Rahu–Ketu axis from Swiss Ephemeris positions with the Lahiri ayanamsa — the same engine behind every AskSoma chart. The calculator flags the classical combinations; it does not pronounce a verdict. Pitra Dosha is a spectrum, not a switch: a Sun tightly conjunct Rahu in the 9th reads very differently from a mild aspect softened by a benefic like Jupiter.

We will say this plainly, because the field is full of people who won’t: Pitra Dosha is never a reason to buy your way out of fear. The classical response is remembrance — tarpana, shraddha, feeding those who cannot repay you — acts of gratitude to the people whose lives made yours possible. Done in that spirit they steady the 9th house. Sold as panic-priced "dosha removal," they help no one but the seller.

Where Pitra Dosha shows in a chart

No single placement is a sentence — the tradition looks for the Sun or the 9th house shadowed by the nodes or a hard Saturn. The more of these that stack, and the tighter the contact, the stronger the reading.

Sun conjunct Rahu

The classic signature — the father-karaka eclipsed by the shadow planet. Often a story of an absent, idealised, foreign, or complicated father, and a sense of lineage that feels interrupted rather than passed on cleanly.

Sun conjunct Ketu

The Sun dimmed by Ketu reads as an inherited detachment — a father who was present but unreachable, or spiritual leanings that pull you away from worldly ambition the family expected.

Rahu or Ketu in the 9th house

The node sits directly on the house of ancestors and dharma. Fortune arrives on a delay and by unusual routes; belief systems get rebuilt rather than inherited.

9th lord in a dusthana (6th, 8th, 12th)

The ruler of your fortune house tucked into a house of debt, upheaval, or loss — a sign the ancestral thread runs through difficulty before it steadies.

Saturn afflicting the Sun or 9th lord

Saturn’s pressure on the father-significators reads as duty, delay, and a lineage marked by hardship or unpaid obligation more than by curses.

Moon–Rahu contact (maternal echo)

Not Pitra Dosha proper, but many charts carry a parallel Matru (maternal-line) strain here. Worth reading alongside, because family karma rarely runs down one side only.

The classical remedial observances

Every one of these is an act of remembrance, not a transaction. They are strongest when done with attention and gratitude, and traditionally during Pitru Paksha (the fortnight the ancestors are honoured).

Tarpana (water offering)

The simplest, most repeatable rite — offering water to the ancestors, especially during Pitru Paksha and on the new-moon (Amavasya) tithi. A daily discipline more than a one-off.

Shraddha & Pinda Dana

The annual death-anniversary rite, offering pinda (rice balls) and feeding brahmins or the needy in the ancestors’ name. The core observance the 9th house responds to.

Tripindi Shraddha

Performed where three generations’ rites were missed or incomplete — a way of catching up on unpaid remembrance. Traditionally done at Trimbakeshwar and similar tirthas.

Gaya Shraddha

The pilgrimage rite at Gaya, considered the most complete way to settle ancestral debt in the classical texts. A once-in-a-life journey, not a monthly fee.

Feeding crows, cows, brahmins & the needy

Crows are held to carry offerings to the ancestors; feeding those who cannot repay you is the everyday, low-cost form of the same gratitude.

Reading a stacked Pitra Dosha

1. Say the calculator shows the Sun conjunct Rahu, and that pair sitting in the 9th house.
2. That is two signatures at once: the father-karaka eclipsed (Sun–Rahu) AND the node on the house of ancestors (9th) — they reinforce each other.
3. Now check the 9th lord: if it sits in the 12th (loss/foreign lands), the reading strengthens again — fortune arrives late and often far from home.
4. Finally look for relief: a Jupiter aspect on the 9th, or the Sun in its own sign Leo, softens the whole picture considerably.

Three afflicting factors with no benefic relief reads as a genuine ancestral theme worth honouring with regular tarpana. The same Sun–Rahu with a Jupiter aspect is a gentle note, not a life sentence — context is everything.

What this tool can NOT tell you

• This tool flags classical combinations from your chart — it cannot confirm actual events in your family’s history. Only your relatives and records can do that.
• Pitra Dosha strength depends on the whole chart: dignity of the Sun, benefic aspects, and the running Dasha all change how much it matters. A flag is a starting point, not a diagnosis.
• It is never a medical, legal, or financial ruling, and it is never a reason to buy fear-priced "removal." Remedies here are remembrance, not payment.
• A quiet chart with no flags does not mean your ancestors are forgotten — honouring them is good practice regardless of what any calculator says.

Free Pitra Dosha Calculator — frequently asked

What causes Pitra Dosha in a birth chart?

Pitra Dosha forms when the 9th house (house of father, dharma, and ancestors) is afflicted — typically by Rahu conjunct Sun, Rahu in the 9th house, affliction to the 9th lord, or Sun-Saturn combinations in specific houses. It indicates unresolved ancestral karmic debts that manifest in the native's life.

What are the effects of Pitra Dosha?

Common manifestations include delays in progeny, repeated obstacles in career or finances despite talent, unexplained health issues, difficulty in marriages, and a pattern of things falling through at the last moment. The specific effects depend on which planets and houses are involved.

Can Pitra Dosha be completely removed?

Vedic tradition holds that consistent remedial measures can significantly reduce the effects. Key remedies include performing Pind Daan at Gaya (Bihar), regular Shraddh rituals on Pitru Paksha, feeding Brahmins on Amavasya, and donating to the needy on father's or grandfather's death anniversary.

Is Pitra Dosha the same as ancestral curse?

Not exactly. Pitra Dosha is better understood as unresolved ancestral karma that the native carries forward, rather than an active curse. It reflects duties or karmic debts from the paternal lineage that need to be addressed through specific spiritual practices and good deeds.
