Doshas in Vedic astrology: what they are and what they are not

The word dosha is Sanskrit for a fault or defect. B.V. Raman's Muhurtha glosses it as 'dosha (evil)', and Wikipedia renders mangala dosha as 'mars defect'.

In astrology, a dosha is a named chart condition that some texts or traditions treat as unfavourable. The definition says nothing about what a condition does to a person, because this page does not make such claims.

Six named doshas are covered here: Manglik (Kuja) dosha, Sade Sati, Shani dhaiya, Kaal Sarp dosha, Pitra dosha, and Nadi and Bhakoot dosha in kundali matching. Each has its own lesson with the calculation, the sources and the cancellations.

The table below lists the six doshas in this module, what each one checks, and where it comes from. Read it as a map: each row has a source you can check for yourself.

Take the first row. Manglik (Kuja) dosha checks Mars in certain houses, counted from the lagna (the Vedic ascendant, the sign rising on the eastern horizon), the Moon or Venus.

Its sources are Brihat Parashara Hora Shastra (BPHS, R. Santhanam's translation) chapter 80 and a Kerala verse quoted by B.V. Raman.

The second and third rows are Saturn transits counted from the Moon. Phaladeepika (Mantreswara), chapter 26, describes Saturn's transit through signs counted from the Moon; Sade Sati and Shani dhaiya are later names for parts of that cycle. The counting from the Moon is classical; the popular labels are later.

The fourth row is the plainest. Kaal Sarp dosha, where all seven planets sit on one side of Rahu and Ketu (the north and south nodes, two shadow points), is not found in the classical texts used here.

The fifth row shows a split. BPHS chapter 83 speaks of a 'curse of the father' from a previous birth; the popular Pitra dosha, usually defined as the Sun or Moon with Rahu, Ketu or Saturn, is a modern definition that differs from BPHS.

The last row comes from matching. Muhurta Chintamani (Rama Daivajna), chapter 6, is the source for Nadi and Bhakoot dosha, which compare two people's Moon nakshatras (lunar star positions) and Moon signs.

BPHS chapter 80, verse 47, counts the Mars condition only 'without aspect by, or association with any benefic'. In plain words: if a benefic planet (a traditionally favourable one, like Jupiter or Venus) aspects or sits with Mars, the condition is not counted as the text states it.

Verses 48 and 49 add that it ceases to have any effect when both partners in a match have it. The text that names the condition also limits it.

Muhurta Chintamani chapter 6, verses 32 to 33 and 36, lists exceptions to Bhakoot and Nadi dosha in matching. In both texts, conditions come with cancellations, and a fair reading includes both.

B.V. Raman, in Muhurtha, wrote of Kuja dosha: 'much is made of the so-called Kuja Dosham and this bugbear has been the means of destroying the happiness of many families by preventing marriages otherwise very eligible'. He added: 'Kuja Dosha does not deserve that consideration which is now being paid to it.'

On matching, in the Marriage chapter of the same book, Raman wrote: 'The kutas or the units of agreement should be considered only when there is general sympathy between the horoscopes of the parties to be brought together.' He called the practice of rejecting horoscopes only because certain kutas do not agree 'highly defective'.

The May 2012 newsletter of the Journal of Astrology (Institute of Astrology, Bharatiya Vidya Bhavan, New Delhi, whose research K.N. Rao guided) reported that the Institute's statistical research showed 'Kaal Sarpa dosha, Sade Sati and many such common prescriptive approaches were exploitative', used as tools 'by self-styled, unscrupulous astrologers for selfish gains'.

Wikipedia describes the belief around mangala dosha as 'a Hindu superstition, prevalent in India'. That is Wikipedia's characterisation, quoted and attributed, not Skybond's verdict on anyone's chart.

P.V.R. Narasimha Rao (PVR), author of Vedic Astrology: An Integrated Approach, writes in section 25.2 that standard transit results 'are given only for reference. In reality, not everyone with the same janma rasi (moon sign) experiences the same results'.

He adds that 'the results given by planets depend on what they stand for in the natal chart'.

B.V. Raman makes a similar point in Hindu Predictive Astrology, chapter 34: 'There is no denying the fact that the birth horoscope directly affects Gochara results.' Gochara means transits.

On the natal chart itself, PVR writes in section 34.1 that planetary positions at birth decide 'the basic pattern and not all the minute details'. And: 'Though the basic pattern cannot be easily altered, the exact details can be altered by exercising free will.' A named condition is one feature of a pattern, not the pattern.

Skybond's chart engine does not compute or label doshas, and Skybond does not sell remedies, gemstones or rituals. Learn pages make no predictions about the reader and give no remedies.

The four cards above are the questions to carry into every dosha lesson: which text, how calculated, cancelled or not, and how it sits with the whole chart.

Every lesson in this module follows the same shape: the calculation, what the classical texts say, the cancellations and where schools differ, and what the dosha does not mean.

If someone has already named a dosha in your chart, start with the lesson on reading dosha claims. It walks through the four questions in the cards above with worked examples, so you can check any claim against its own source.
