Doshas

Pitra Dosha is a popular label, usually for the Sun joined or afflicted by Rahu or Saturn, often tied to the 9th house. This app does not compute it. Here is what BPHS, Saravali and the Bhrigu Sutras do and do not say, how often the popular condition occurs, and a worked chart showing only the positions.

In short

This app does not flag Pitra Dosha. The name does not occur in any searchable astrology text in its corpus; the nearest classical material is a BPHS rule about the Sun as indicator of the father and a BPHS chapter on childlessness attributed to previous births. With no single sourced rule, the app shows the underlying positions and leaves the label alone.

This app does not flag Pitra Dosha. No calculator returns it, no report lists it, and the birth chart calculator will never print the words. This page explains why, with the same care the app gives to the doshas it does compute: what the popular label means, what the classical books in this app's source library actually say, how often the popular condition turns up, and a worked chart that shows only the positions underneath it.

What Pitra Dosha is in popular usage

Pitra (also written Pitri or Pitru) means the ancestors, and in particular the father's line. A dosha is a named fault in a chart. In current popular writing, Pitra Dosha is the label given to a Sun that is joined or afflicted by Rahu or by Saturn, and the condition is often tied to the 9th house, the house of the father and of fortune. This repo's own feasibility research summed up the market version as "a Sun afflicted by Rahu/Saturn in or from the ninth house" read as a sign of ancestral karma. Versions differ on the details: some count only a shared sign, some count aspects, some look at the 9th house from the ascendant, some at its lord.

That description is popular usage, not a classical rule. It is reported here so the reader knows what the name refers to. It is not quoted from any book this app uses, because none of them contains it.

The condition used for this page's numbers

To give the page real figures, the content tooling searched this engine's charts for the simplest common form: the Sun in the same sign as Rahu, or in the same sign as Saturn. That test is used below for two things only, a frequency count and the choice of a worked example. It is not a rule the app runs on anyone's chart, and it is not offered as the correct definition.

What the classical texts say

A search of the corpus for "pitr" finds three lines in the Brihat Parashara Hora Shastra translation and none in Saravali, the Bhrigu Sutras, Advanced Predictive Astrology or Daivajna Vallabha. (The corpus holds two BPHS files, but they are the same Santhanam/Sharma translation set differently, so they count once.) None of the three BPHS lines names a dosha:

  • Ch. 29 Sl. 1-3 lists the names of the twelve Arudha Padas, and "Pitru" is the Pada of the 9th house. It is a name for a computed point, not a fault.
  • Ch. 32 Sl. 13-17 names a Pitru Karak among the seven Chara Karakas, the "inconstant significators" ranked by degree. Any graha can hold the role; this app computes it on the Chara Karaka calculator.
  • Ch. 70, in the Ashtakavarga chapter, says the Sun is the PitraKarak, so matters of the father are read from the Sun's Ashtakavarga.

The phrase "Pitra Dosha" (or "Pitru Dosha") occurs nowhere in the searchable corpus. The word "dosh" itself occurs once in the whole BPHS translation, as "Rikta-Bhadra Dosha", a term for an unsuitable day in the remedial chapters, not a chart condition. Jyotisha-Siddhanta-Sara is held only as page images, so it could not be searched and is not cited here.

BPHS on the Sun as indicator of the father

The nearest classical rule to the popular idea is BPHS Ch. 9 Sl. 43-45. It says the Sun is the indicator of the father for all beings, and the Moon of the mother. If the Sun receives a drishti from one or more malefics, or is hemmed between them, the text reads "evils to father"; malefics in the 4th, 6th or 8th from the Sun are read the same way. The sloka closes by asking the reader to estimate the strength of the grahas involved. BPHS Ch. 3 Sl. 11 counts the Sun, Saturn, Mars, the waning Moon, Rahu and Ketu as malefics, so Saturn and Rahu are both covered.

Three things separate this from the popular label. First, it is a rule about the father as a person, not about ancestors or inherited karma. Second, it does not mention the 9th house at all. Third, it sits in a chapter, Ch. 9 "Evils at Birth", whose surrounding slokas (Sl. 34-42, headed "Evil to Father") time the father's absence or death from particular placements. This page does not reproduce those; it notes only that they exist and that this app does not use them.

BPHS is also not consistent about who signifies the father. Ch. 32 Sl. 18-21 says the stronger of the Sun and Venus indicates the father, and lists Ketu among the significators of the father too, and Sl. 22-24 says the father is read from the 9th counted from the Sun, not from the ascendant. Saravali Ch. 8 Sl. 27-28 makes the Sun the father's planet for day births and Saturn for night births. So the classical sources give at least four candidates for the father's significator and no rule for choosing among them. The 9th house page covers what BPHS Ch. 20 says about the 9th itself; that chapter names no dosha.

BPHS Ch. 83: the chapter usually cited

The classical passage most often connected with Pitra Dosha is BPHS Ch. 83, which the translation titles "Effects of Curses in the Previous Birth". Here is what the chapter itself contains, read from the translation.

  • Its subject is narrow. Maitreya asks (Sl. 1-3) what causes a person to be without a son, and the chapter answers in terms of the 5th house, its lord, Jupiter as significator of children, and the ascendant lord. The translator adds a note that "childlessness" in the chapter should be read as want of male issue.
  • It lists several groups of combinations, each attributed to a different relation in a previous birth: a serpent, the father (Sl. 20-30), the mother, a brother, a maternal uncle, a Brahmin, the wife, and, in Sl. 95-105, the failure to perform the Shraddha rites for a parent. The father group and the Shraddha group are the closest the text comes to the modern "ancestral" idea.
  • Every group is a set of compound conditions. The father group, for example, involves a debilitated Sun hemmed by malefics in the 5th, exchanges between the 5th and 10th lords, malefics in the ascendant and the 5th, and similar multi-part combinations. None is the simple "Sun with Rahu" or "Sun with Saturn" of popular usage, and none is located in the 9th house.
  • Every group is followed by a remedy: for the father group, Shraddha at Gaya, feeding Brahmins, Kanyadana and the gift of a cow (Sl. 31-33); for the Shraddha group, Pinda Dana, Rudra Abhisheka and gifts (Sl. 106-108). Ch. 84 continues with remedies for every graha. The text prescribes propitiation; this app does not.

Saravali, the Bhrigu Sutras and Advanced Predictive Astrology

Saravali Ch. 15 gives a reading for every pair of the seven classical grahas in one house (Sl. 2-22). Its Sun-Saturn entry (Sl. 7) is a mixed list of traits and family circumstances; it says nothing about ancestors. Rahu and Ketu do not appear in that chapter at all, so Saravali has no "Sun with Rahu" reading to cite. The Sun-Saturn conjunction page covers the pair in full.

The Bhrigu Sutras come closer in one place. Under the Sun in the 5th house (Sutras 51-58, p. 22) they say that if the Sun is with Rahu or Ketu, loss of children is attributed to the Serpent God, and then add that this does not happen if a benefic, Jupiter or Venus, aspects the combination. The same book reads Rahu or Ketu in the 9th (Sutra 24, p. 113) bleakly, and its editor's notes immediately quote two later works that disagree; one of them, Chamatkar Chintamani, reads Rahu in the 9th as kind-hearted and fond of pilgrimage. See Rahu in the 9th house for that placement on its own.

Advanced Predictive Astrology, a modern case-study book, says on p. 154 (Vol. II, "Determination of good time and bad time") that a Sun-Saturn conjunction is "never welcome" and that the native "often maintains a distance from the father", and calls the combined influence of the Sun, Saturn and Rahu "separative" for whatever house it falls on. On p. 25 it lists Saturn-Rahu and Jupiter-Rahu among "controversial planetary groups" and reads them as coming from the previous birth. It never uses the name Pitra Dosha.

Why the app does not compute Pitra Dosha

Every dosha this app flags rests on a rule it can state, cite and test. For Pitra Dosha there is no such rule. This repo's feasibility research, and an adversarial review of that research, both concluded that it should not be built, for reasons that hold independently:

  1. The name, the 9th-house location and the ancestral-karma meaning appear in none of the searchable sources. Building it would mean inventing all three at once.
  2. The one sourced ingredient, the Sun as father, is contradicted inside BPHS itself (Ch. 9 against Ch. 32) and again by Saravali, with no rule for choosing between them.
  3. Even the narrow BPHS Ch. 9 rule depends on "hemmed between malefics", and the corpus gives no general definition of hemming that could be coded without choosing a threshold the text does not state.
  4. The chapter usually cited, Ch. 83, is about a person's sons, not their ancestors, and is built as condition followed by ritual. A feature built on it would be a fear-then-remedy product, which this app declines to make.

The result is a deliberate gap. The app would rather show the positions and say plainly that the label is not computed than print a verdict it cannot trace to a text.

What the app does compute that touches the same placements

  • Positions and houses. The birth chart gives every graha's sidereal sign, degree, nakshatra and, with a birth time and place, its whole-sign house. Two grahas in the same sign are visibly together; the app has a learn page for each pair, such as Sun-Rahu conjunction.
  • Combustion. Each graha carries a combust flag when it is within its limit of the Sun, using Kannan's orbs (Moon 12 degrees, Mars 17, Mercury 14 or 12 when retrograde, Jupiter 11, Venus 10 or 8 when retrograde, Saturn 15). See combustion.
  • Aspects. The app's whole-sign aspect table gives every graha the 7th aspect, Mars the 4th and 8th, Jupiter the 5th and 9th and Saturn the 3rd and 10th; Rahu and Ketu get the 7th only. See graha drishti.
  • The doshas it does flag. The dosha list on a full chart holds Kendradhipathya, Mangal, Kaal Sarp and three Dhan Bhava caution checks from BPHS Ch. 42, each with its source in the code. Pitra is not among them.

How common the popular condition is

The content tooling walks through 3,000 birth moments from 1985 to 2060 at New Delhi, nine days and a few hours apart, and counts how many meet a condition. These are sampled birth moments, not people.

Condition (popular form, not computed by the app)Moments of 3,000

Sun in the same sign as Saturn273
Both at once19

Sun in the 9th house249
engine-facts.mjs pitra-dosha and scratchpad facts.mjs, run 2026-10-13. Sidereal (Lahiri), whole-sign houses, New Delhi.

About one sampled moment in six meets the simple shared-sign version. The reason is plain arithmetic: the Sun passes through all twelve signs in a year, a month or so in each, while Rahu and Saturn move slowly, so in most years there is a stretch of weeks when the Sun is in Rahu's sign and another when it is in Saturn's. A condition that common cannot single anyone out, which is one more reason not to print it as a verdict.

Worked example: the positions only, 20 April 1985

The first moment in the walk that meets the example condition is 20 April 1985, 13:24 IST, New Delhi. Anyone can enter that date, time and place in the birth chart calculator and see the same positions. The table shows the positions only; the app attaches no Pitra Dosha verdict to them.

The positions only. engine-facts.mjs pitra-dosha, run 2026-10-13. Ascendant Cancer 26.31. Sidereal (Lahiri), whole-sign houses.

What the positions show, read plainly:

  • The Sun shares Aries with Rahu, 19.18 degrees apart. That is the only reason this chart was picked. Saturn is not with the Sun; it is in Scorpio, 153.56 degrees away.
  • The Sun is exalted in Aries and sits in the 10th house. The Moon is 1.13 degrees from it: the engine's lunar day for this moment is the 1st tithi of the bright half, a new Moon, and the Moon is flagged combust.
  • In the app's aspect table the Sun's house receives one aspect, Ketu's 7th from the 4th. Saturn's 3rd, 7th and 10th aspects from the 5th fall on the 7th, 11th and 2nd, not on the Sun.
  • The 9th house is Pisces. It holds Mercury (debilitated) and Venus (exalted, retrograde) and receives no aspect. Rahu is not in it, and neither is the Sun.
  • The 5th house, the one BPHS Ch. 83 is concerned with, holds Saturn in Scorpio and receives Mars's aspect.

So the same chart meets the shared-sign popular test and fails the 9th-house version, and the BPHS Ch. 9 Sl. 43 test would turn on whether Ketu's aspect counts and how much weight an exalted Sun deserves, which the sloka leaves to the reader's estimate. That is the problem in miniature: three readings, three answers, and no text that says which is right.

What the app does say about this chart: its dosha list returns Kendradhipathya Dosha (Mild), with Mangal Dosha and Kaal Sarp Dosha absent, and its yoga check finds Durudhura, Ubhayachari, Pasa, Argala Raj and Raj Yoga (Kendra-Kona). Each of those is a coded rule with a source; the Pitra label is not.

Exceptions the texts themselves state

Because there is no Pitra Dosha rule, there is no list of its cancellations either. The nearby classical rules do carry their own qualifications, and they point the same way:

  • BPHS Ch. 9 Sl. 43-45 ends by telling the reader to estimate the strength of the grahas involved before judging. An afflicted but strong Sun is not, on the text's own terms, read the same as an afflicted weak one.
  • The Bhrigu Sutras' Sun-with-Rahu-or-Ketu reading in the 5th is withdrawn in the same sentence if Jupiter or Venus aspects the combination.
  • Advanced Predictive Astrology places most of its Sun-Saturn remarks in a chapter on good and bad times, as readings of the two grahas' joint dasha periods, and its Sun-Saturn-Rahu remark depends on which house the influence falls on.

What Pitra Dosha does not tell you

The house view on doshas, set out in Mangal Dosha: what it is and is not and Kaal Sarp Dosha explained, is that a named rule describes positions and is not a verdict on a life. For a label with no fixed rule, that applies with more force.

  • It does not describe your family. No text in the corpus links a Sun-Rahu or Sun-Saturn placement to ancestors, and BPHS Ch. 9 Sl. 43 itself asks for the strength of the grahas to be weighed before anything is read.
  • It is not one thing. Different writers mean different conditions by the name, so two sites can disagree about the same chart without either making an arithmetic error.
  • It is common. By the simplest version, about one sampled birth moment in six has it.
  • It does not time anything. There is no period, transit or dasha attached to the popular label.
  • It is not a reason to buy anything. Ch. 83 pairs every condition with a ritual; this app reports that and prescribes nothing.

For the grahas themselves, read Rahu in Vedic astrology and Saturn in Vedic astrology. The other popular labels this app does not compute have their own pages: Guru Chandal Dosha, Shrapit Dosha and Grahan Dosha. How positions are computed is on the methodology page.

Does this app check for Pitra Dosha?
No. It does not compute or display Pitra Dosha in any calculator or report. It shows the positions the popular label is built from, so you can see them yourself.
Is Pitra Dosha mentioned in BPHS?
Not by name. The translation this app uses has "Pitru" only as the name of the 9th-house Arudha Pada, as a Chara Karaka rank and in the remark that the Sun is the PitraKarak. The closest rules are Ch. 9 Sl. 43-45 on the Sun as indicator of the father and Ch. 83 on childlessness attributed to previous births.
What does BPHS Ch. 83 actually say?
It lists compound combinations, mostly involving the 5th house, its lord and Jupiter, that it attributes to wrongs in a previous birth against a father, mother, sibling, uncle, Brahmin, wife or serpent, or to unperformed rites for parents. Its stated subject is want of a son. Each group ends with a prescribed ritual. This app reports the chapter and does not apply it.
Is the Sun with Rahu the same as Pitra Dosha?
Only in some popular definitions. In this app it is simply a shared sign. In the 3,000-moment sample it occurs 251 times. The Sun-Rahu conjunction page covers what the texts say about the pair.
Why does another website say I have Pitra Dosha?
Because it uses a definition of its own. The name has no single classical rule, so sites differ on whether they count Rahu, Saturn, Ketu, aspects, the 9th house or its lord. Compare the positions, which should agree, rather than the label.
What does the app show instead?
The Sun's sign, degree, house and dignity, whether it is combust, which grahas share its sign and which aspect its house, and the doshas and yogas it can source. Start with the birth chart calculator.
Does the app recommend remedies for Pitra Dosha?
No. BPHS Ch. 83 and Ch. 84 prescribe rites and gifts; this app prescribes no rituals, mantras, gemstones or donations for this or any other result.
