Naga Dosham and Marriage, How It Is Read in Matching

Naga dosham, also called sarpa dosham or Rahu-Kethu dosham, is the name Tamil and Kerala astrologers give to Rahu or Ketu sitting in certain houses of the jathagam, most often the 1st, 2nd, 7th or 8th counted from the lagnam. In marriage matching, most jothidars handle it like chevvai dosham: a jathagam with naga dosham is matched with another that has a similar dosham.

It is a chart dosham, read from one person's horoscope. It is not one of the 10 poruthams.

What Naga Dosham Means

Rahu and Ketu are the two shadow planets, always opposite each other in the chart. In Tamil they are called the naga grahas, the snake planets. When either sits in a house linked with marriage, family or long life, many jothidars call it naga dosham.

The houses most often named:

Since Rahu and Ketu are always 180 degrees apart, Rahu in the 1st means Ketu in the 7th, and Rahu in the 2nd means Ketu in the 8th. So these four houses come in two pairs.

Some astrologers add the 4th and 5th houses. Many also check the same houses from the moon (chandra lagnam) and from Venus. Two jothidars may disagree about the same chart, because they use different lists. That is normal, and it is the first thing to ask about: "Which houses did you count?"

Naga Dosham and Kala Sarpa Dosham Are Different

Families often mix up the two.

Our page on doshas in kundli for marriage explains kala sarpa dosham and the other chart doshas.

How Tamil Jothidars Read It in Matching

The rule most Tamil jothidars follow is dosha samyam, balance. A naga dosham jathagam is matched with another naga dosham jathagam, the same way a sevvai dosham jathagam is matched with a sevvai dosham one.

Many jothidars do this as part of papa samyam, the wider check of malefic planets in both charts. Rahu, Ketu, Mars (Sevvai), Saturn (Sani) and the Sun are counted in the sensitive houses of both charts and compared. If the boy's chart carries as much dosham as the girl's, the match is treated as balanced.

So a girl with Rahu in the 7th is usually matched with a boy who has Rahu or Ketu, or sometimes Mars, in a similar position. A boy with no malefics in those houses is, in the strict view, not matched with her. Many jothidars relax this when the rest of the porutham is strong.

Our page on jathagam porutham in Tamil shows how papa samyam fits into the full match.

How Kerala Astrologers Read It

Kerala jothishis give the dosha check a lot of weight, as they do with chovva dosham. Rahu and Ketu are counted along with Mars, Saturn and the Sun when the papa (malefic) points of both charts are compared.

Kerala also uses sarpa dosham in a second sense. Many families link it with the snake worship of their tharavadu (ancestral home), for example a neglected sarpa kavu, the sacred grove for snake deities, or harm done to snakes in the past.

In that sense, an astrologer reads it through prasnam (a question chart), not only from the birth chart. The remedy is then a puja for the family's snake deities, not a change in matching.

Exceptions Jothidars Apply

Before writing "naga dosham undu", most jothidars check a few things. The ones quoted most often:

1. Rahu or Ketu in a friendly or strong sign, which many consider to soften the dosham.
2. Jupiter (Guru) aspecting the house or the planet.
3. The age of the person. Some jothidars treat the dosham as weaker after a certain age, the way some treat chevvai dosham after 28.

These rules differ widely. Ask the jothidar who wrote the jathagam which ones he applied, and get it in writing if a proposal depends on it.

Naga Dosham Pariharam and Temples

Families with naga dosham often do a pariharam (remedy) before or during the match search. These are the temples families name most often.

The Tamil Nadu temple details are from the TN Temples Project pages on Thirunageswaram and Keezhperumpallam.

Other common pariharams are milk abhishekam to the naga idols under a peepal tree, prayers on Tuesdays or during Rahu kalam, and fasting on Naga Panchami or Naga Chathurthi.

A pariharam is done in faith. It does not move Rahu or Ketu in the chart, and most jothidars will still look for a matching dosham afterwards. No temple visit should be sold to a family as a guarantee.

Can a Naga Dosham Girl or Boy Marry a Non-Dosham Partner?

Under the strict rule, jothidars prefer a partner with a similar dosham. Many still allow a match if the dosham is mild, if one of the exceptions applies, or if other malefics in the partner's chart balance it in papa samyam. Ask two jothidars if the first answer worries you.

The worry should be the same for a boy and a girl. In practice, girls' families feel it far more, and that is a habit worth breaking. Families who have a long wait for a match because of a dosham may find our page on sevvai dosham useful too, since the same balance rule applies there.

Writing It on the Biodata

Tamil biodatas sometimes add a line like "Dosham: Rahu-Kethu (naga) dosham undu" or "Dosham: Illai". Many families leave it off and send the jathagam separately.

Our maker has a Chevvai / Manglik field with No, Yes, Partial and Don't Know, but no field for naga dosham. Use Add Your Own Field in the Horoscope section, with "Dosham" as the field name and your jothidar's words as the details.

The maker fills rasi, nakshatra with pada, and lagna from the birth details and prints them as text. It does not draw the rasi kattam, so send your jothidar's jathagam along if the other side wants to check the dosham. The jathagam biodata format shows how the horoscope rows look.
